TRACE-ELEMENT DATA OF STREAM-SEDIMENT HEAVY-MINERAL CONCENTRATE SAMPLES FROM

BRADFIELD CANAL QUADRANGLE, SOUTHEASTERN ALASKA

by

INTRODUCTION

A reconnaissance geochemical sampling program was conducted during 1978

and 1979 in the Bradfield Canal 1:250,000-scale quadrangle, southeastern

Alaska. The sampling was done to assist with evaluation of mineral resources

in the area as part of the Alaska Mineral Resource Assessment Program

(AMRAP). This report contains the analytical data for 219 stream-sediment

heavy mineral concentrate samples collected in the Bradfield Canal quadrangle

during the summer of 1979. These samples comprise all of the heavy mineral

concentrate geochemical samples known to have been collected by the U.S.

Geological Survey within the Bradfield Canal quadrangle through 1979. A brief

statistical summary of these analytical data is included in this report.

OTHER SOURCES OF DATA

Analytical data from rock and unconcentrated stream-sediment geochemical

samples collected within the Bradfield Canal quadrangle are contained in two

companion reports (Koch and others, 1980a, b). Geochemical data from rock

samples collected by U.S. Bureau of Mines engineers at selected prospects in

the Bradfield Canal quadrangle are reported in Koch and others, (1976).

Analytical data from rock and stream-sediment samples collected in the

Ketchikan and Prince Rupert quadrangles, south of the Bradfield Canal

quadrangle, are contained in several earlier reports (Koch and Elliott 1978a,

b, c). Data from all of the normal U.S. Geological Survey rock and stream-

sediment geochemical samples collected in the Ketchikan and Prince Rupert

quadrangles and from the rock, stream-sediment, and heavy-mineral concentrate

samples from the Bradfield Canal quadrangle are available on magnetic computer

tapes (Koch, Van Trump, and McDanal, 1978; Koch, O'Leary, and Risoli, 1980).

GEOLOGIC SETTING AND STUDIES IN THE BRADFIELD CANAL AREA

The United States portion of the Bradfield Canal quadrangle area is

dominated by amphibolite-facies schists and gneisses and Cretaceous to Miocene

granitic plutons of the Coast Range batholithic complex. A segment of the

Coast Range megalineament (Brew and Ford, 1978), a major structural and

topographic feature more than 500 km long, runs diagonally across the

southwestern portion of the map area from Nelson Glacier through the areas

near Eagle Bay and Eagle Lake. East of this zone, isolated roof pendants of

paragneiss and schist lie amid nearly continuous orthogneisses, spectacular

migmatites, and granitic plutons with compositions ranging from diorite and

quartz diorite to quartz monzonite (adamellite) and alkalai-feldspar

granite. Farther east, along the Canadian boundary, are roof pendants of

lower grade metasedimentary, metavolcanic, and carbonate rocks. West of the

megalineament, granitic rocks occur as discontinuous bodies within schist and

paragneiss.

The earliest comprehensive discussions of the geology of the Bradfield

Canal area are contained in reports by Wright and Wright (1908) and Buddington

and Chapin (1929). Buddington (1929) also described the Hyder mining district

located near the Canadian border 120 km northeast of the town of Ketchikan.

Recent geologic investigations by the U.S. Geological Survey in the Bradfield

Canal quadrangle began in 1968 with mapping in the Hyder area (Smith, 1977).

A mineral resource evaluation of the Granite Fiords Wilderness Study area,

which included a large portion of the eastern part of the Bradfield Canal

quadrangle, was conducted in 1972 and 1973 (Berg and others, 1977). Field

studies continued as part of the AMRAP program in 1978 and 1979. Other

discussions of Coast Range geology include reports by Hutchison (1970),

Roddick and Hutchison (1974), Brew and others, (1976), and Brew and others

(1977).

SAMPLING

Most of this recently glaciated study area is steep and rugged with

elevations ranging from sea level to 2300 meters. Rain- and snowfall are

heavy and precipitation continues year-round. Sediment in the resulting swift

streams is essentially all detrital material derived from mechanical erosion

of bedrock and, to a lesser extent, reworking of locally-derived glacial

deposits. The bulk of most sediment collected ranges in size from very fine

sand to pebbles. Samples from near the toe of a glacier may consist entirely

of very fine sand and rock flour. Otherwise, samples with a large percentage

of silt- and clay-size material are rare.

Standard procedures were followed in collection, preparation, and

analysis of the stream-sediment heavy-mineral concentrate samples. Those

collected from shoreline sites were obtained above highest high tide level

whenever possible, to eliminate contamination by sediment introduced by salt

water currents. Samples generally consisted of 7 to 10 kg of the finest, most

organic-free sediment in the active stream channel. If the sediment was

relatively coarse, it was passed through an 8-mesh (approx. 2 mm) stainless

steel screen before being put into cloth bags. In camp, where a smoothly-

flowing river was available, the samples were rough-panned in standard "gold

pans" to remove organic and clay-sized material, and to concentrate the heavy

minerals. Samples were then air-dried or oven-dried at low temperatures and

shipped to the lab for further preparation.

LABORATORY SAMPLE PREPARATION AND ANALYTICAL PROCEDURES

Laboratory preparation and analysis was performed by members of the

Branch of Exploration Research (BOER) of the U.S. Geological Survey. Samples

were dry-sieved and the -20 mesh fraction was settled through undiluted

bromoform (specific gravity 2.86). The light fraction was discarded.

Magnetic minerals, primarily magnetite and ilmenite, were removed from the

heavy fraction in the following manner. The sample was spread out over a flat

tray and passed under a powerful electromagnet. The magnet of a Frantz

Isodynamic separator, set at 1.8 amps, was shielded with a mylar sheet and

used for this purpose. The sheet could be removed for cleaning between

samples. The samples were not passed through the track of the Frantz

separator in the standard manner.

After the magnetic treatment, samples were ground with a mortar and

pestle. A split of this material was analyzed for copper, lead, and zinc by

standard atomic absorption spectrophotometry procedures (Ward and others,

1969). The samples were also analyzed for 31 elements by a rapid six-step

semiquantiative emission spectrographic method. The technique used for

spectrographic analysis is similar to that described by Myers and others

(1961) and Grimes and Marranzino (1968), with the following exception. To

limit spectral interference caused by high iron concentrations, 5 mg of ground

sample (half the normal amount) was added to 25 mg of a 4:1 mixture of

•'•Any use of trade names and tradmarks in this publication is for descriptive purposes only and does not constitute endorsement by the U.S Geological Survey

graphite and ground pure Arkansas quartz, to comprise a normal 30 mg

analytical load. Spectral lines were recorded on film and visually compared

to standards which are based on 10 mg samples. The resulting values were

doubled to produce the data reported here. Doubled values occurring between

six-step reporting values were "rounded up" to the higher reporting value

(example: 2 ppm X 2 = 4 ppm and is reported as 5 ppm). This procedure raises

the limits of analitical determination and may affect the analytical precision

as discussed below. The semiquantitative spectrographic analyses were

performed by D. A. Risoli and the atomic-absorption analyses by

R. M. O'Leary. Sample preparators were N. G. Courtright and G. G. VanGaalen.

GEOCHEMICAL DATA

Locations of sample sites are identified by 7 character station numbers

on plate 1. The analytical data for the samples are given in table 5 and are

identified by a sample number which consists of the station number, with the

letter "P" appended to it. Analyses are also identified in table 5 by a 6

character laboratory number; often called the "Tag Number". Locations are

indicated in table 5 by latitude and longitude coordinates as degrees,

minutes, and seconds.

Analytical Values

Analytical results are reported as percent of the sample (for

spectrographic analyses of Fe, Mg, Ca, and Ti) and as parts per million (ppm)

for all other analyses. The distribution of values for some of the

determinations is truncated at one or.both ends by the limits of

determinability for that analytical procedure. The limits of determination

and the units used for each analysis are listed in table 1 (page 7). Because

only half as much sample material is analyzed for heavy-mineral concentrates

as is used for spectrographic analyses of other materials (for example of rock

or unconcentrated stream-sediment samples), the determination limits are twice

the normal limit values; rounded up to the next six-step reporting value when

doubling produced a value not on the six-step scale.

A single-letter symbol is used by BOER analysts to indicate that no

analysis was performed for an element or that the analytical result is outside

the limits of determinability. These symbols (commonly called "qualification

codes") are used in the statistical summary but some are represented

differently in the data table. An explanation of both forms is listed in

table 2. The qualifier T does not appear in these data.

Because the original computer printout is used in tables 4 and 5, element

symbols are in capital letters; for example, the symbol for iron, Fe, is shown

as FE, magnesium, Mg, is shown as MG, and so on. In the tables, the prefix S

stands for spectrographic analysis, and AA for atomic absorption.

Results from semiquantitative emission spectrographic analyses (also

referred to as six-step spectrographic analyses) are reported as the

approximate midpoints of class intervals with 6 intervals per order of

magnitude. These class intervals are not evenly spaced when plotted on an

arithmetic scale. The values of interval boundaries and the widths (sizes) of

successive class intervals increase geometrically, with each succeeding

interval boundary and interval width being greater than the last by a factor

of the 6th root of 10 (about 1.4678). These class intervals have a constant

width when the data and interval boundary values are transformed to logarithms

(Miesch, 1967, p. B3-B4).

Use of geometrically-scaled class intervals is appropriate because of

characteristics of both the analytical techniques and of the normal

distribution of elements in geologic materials. Analytical variance tends to

be proportional to the amount of a contituent present; and tends to be

constant for the logarithms of the analytical data (Miesch, 1976, p. 58).

Variability at sample localities is similar, with the amount of variance at a

locality often being proportional to the mean of sample values for that site

and variance tending to be constant when the logarithms of the values are used

(Miesch, 1976, p. 58).

The spectrographic reporting values and the associated class interval

limits and widths are listed in table 3. Element concentrations are reported

as integral powers of 10 times one of the listed six-step reporting values.

Precision

Tests have been performed to determine the analytical precision of the

six-step semiquantitative spectrographic technique used by the Branch of

Exploration Research (Motooka and Grimes, 1976). These tests indicate that,

on the average, the frequency with which values from repeated analyses of the

same sample will fall within the class interval containing the "true" value

(as measured by the mean of a series of analytical runs), plus or minus one

and two consecutive reporting intervals is approximately 83 percent and 96

percent, respectively. For example, if a value is reported as 3.0, the

probability is 0.83 that a second analysis of that sample would be reported as

2.0, 3.0, or 5.0. Because the analysis of heavy-mineral concentrates involves

half of the amount of sample normally used in the six-step spectrographic

method, and because of the additional rounding-off of some values after

doubling, the precision of these determinations is probably less than that

found by Matooka and Grimes for the semi-quantitative spectrographic technique

following standard procedures. This would be especially true where values

tend to fall closer to the determination limits.

The Motooka and Grimes study found analytical variance (reported as a

number of steps of the six-step scale), to be consistent for a variety of

geologic materials and to show no appreciable difference among most elements

or concentration ranges; except near the limits of determinability where

"precision of the analysis is greatly diminished" (Motooka and Grimes, 1976,

p. 2).

An experiment with unconcentrated stream-sediment samples was conducted

by Johnson and others (1980) in similar terrane within the Coast Range, 180 km

north of Bradfield Canal. They determined the amount of variability

attributable to analytical procedures and to variation in sample spacing. For

spectrographic data from that area, which does not contain detected mineral

enrichment, analytical variance ranged from 22 percent (Ni) to 88 percent (Ti,

Mn, V) of the total variance. At the 95 percent confidence level, only four

spectrographically determined elements had analytical variance greater than

the two step average variation determined by Motooka and Grimes; Ti (3 steps),

Cu (3 steps), La (3.5 steps), and Zr (2.5 steps). This study suggests that

for data with a narrow range of values (approaching the level of analytical

variance for that element), the analytical component of total variance will be

responsible for a significant portion of the observed fluctuations but that

for data with a relatively broad range of values, analytical variability

should have only minor effect.

Data from analyses by the atomic absorption methods are not reported on

the six-step scale. They are more sensitive and considered more precise than

spectrographic analyses. Johnson and others determined analytical variance

for atomic absorbtion analyses of Cu, Pb, and Zn to be equivalent to

approximately 1.0, 1.5, and 0.5 steps of the six-step scale respectively, at

the 95 percent confidence level (Johnson and others, 1980, table 3, last

column).

STATISTICAL SUMMARY

The analytical data were processed using a computer to produce the

statistical summary presented in table 4. All distributions are treated in

terms of the six-step class intervals described above and thus the atomic

absorption data are regrouped into these intervals for the summary. The

program output consists of: a frequency distribution table, histogram,

summary of qualified values, range of values, arithmetic and geometric means

and deviations for each element. Table 4 entries are identified in an

explanation at the beginning of that table.

The histograms have a quasi-logarithmic analytical value scale because

they use the class intervals of the six-step semi quantitative scale. All

values qualified with N, L, G, or H were omitted from the histograms. The

resulting statistics are biased and the histograms incomplete.

The summary at the end of table 4 presents estimates of geometric means

and geometric deviations recomputed using a method devised by A. J. Cohen

(Cohen, 1959, 1961; Miesch, 1967) for treating singly censored

distributions. If an element has no qualified data values, the geometric mean

and geometric deviation will be the same in both this summary and on the page

within the table for the particular element. Cohen 1 s method is applicable to

distributions truncated on either the high or low end but, because low end

truncations (left-censored distributions) are much more common in geochemical

problems, the computer program used here was designed only to handle them. If

some values are coded "G", the estimates by Cohen's method where not made for

that element. The estimates of geometric mean and geometric deviation are

unbiased in a strict sense only where the data are derived from a log-normal

parent population, but it has been shown that the method gives satisfactory results

whenever the data are symmetrical about a single mode (Miesch, 1967, p. 85).

11

The geometric mean of N values is the Nth root of their product and can

be computed as the antilogarithm of the arithmetic mean of the logarithms of

the analyses. It is not an estimate of geochemical abundance but of "central

tendency" (or characteristic value) for a frequency distribution which follows

the exponential or "natural growth" law and is thus symmetrical on a

logarithmic scale. The geometric mean has a more stable value than the

arithmetic mean because it is not influenced as strongly by data at the

extremes of the distribution. The geometric deviation can be computed as the

antilogarithm of the standard deviation of the logarithms of the data

values. The geometric mean and geometric deviation are useful for

characterizing many geochemical distributions, which are often more nearly

log-normally than normally distributed. Histograms of the data contained in

this report are more nearly symmetrical on a logarithmic scale than when

plotted with a linear scale. Cumulative frequency plots of the data values

and of their logarithms also demonstrate that these data are distributed in an

exponential fashion. While the geometric mean is the best estimate or

predictor of values for individuals within a log-normal population, it is not

an estimate of geochemical abundance. It can not be used to predict the

amounts of elements present as the arithmetic mean can (Miesch, 1963, 1967).

For further discussion of geometric mean and geometric deviation see Kenny,

(1952) and Miesch, (1963, 1967, and 1976).

BIAS AND VARIABILITY AFFECTING INTERPRETATION

In reviewing the data in table 5 and the statistical summary in table 4,

several sources of bias and variability in the data must be considered.

Factors including time limitations, weather, snow and vegetative cover, type

and amount of sediment accessable, and availability of helicopter landing

12

sites prevented uniform sampling in all areas. Uneven sample density also

resulted from more concentrated sampling of some areas near evidence of

mineralization such as iron-staining or visible metallic minerals. This

practice has biased the data slightly in favor of samples containing values

above background levels. The requirement of truly random sampling—that all

potential samples have an equal likelihood of being selected—is not strictly

met. In addition, these samples were collected from a large area, where

lithologic units of various origins or rock types may comprise several

dissimilar geochemical populations. The samples are not grouped on the basis

of geological or geochemical affinity. The summary of values thus provides

only a general indication of the trends that may be present.

Variability of any value may be influenced by many factors, including the

difficulty of obtaining representative samples of inhomogeneous media,

variation in sample preparation, and variability inherent in the analytical

techniques. It is likely with any large data-set that errors have occurred in

recording, key-punching and editing the data and that some have remained

undetected. Because of these factors, high values for a single element or a

single site should be considered questionable indicators of bedrock

mineralization.
