Corresponding author e-mail: elena@gl.fcen.uba.ar SUMARY Alkaline zeolite assemblage of mordenite, chabazite, heulandita, natrolite and analcime was found in amygdales and veins of basaltic rocks and their breccias at the top level of Ventana Formation. The microphenocrystals in basalts have been partially replaced by pumpellyite, albite, laumontite, chlorite/smectite mixed-layer, smectite, white micas, chalcedony, hematite and iddingsite. This assemblage indicates that the temperature reached was 200° - 260ºC. This temperature seems to be lower in cement of the breccias and amygdales where the zeolite assemblages occur.

Alkaline zeolites with other related minerals were found in amygdaloid basalts and

volcanic breccias at the top level of Ventana Formation. The outcrops are located in the

surroundings of the Nahuel Huapi Lake, Northern Patagonian Andes, Neuquén, Argentina

(41°02’14” S.L.; 71°12’55” W.L. and 41°02’42” S.L.; 71°13’56” W.L.). The age of Ventana

Formation is Paleocene-Oligocene and its top level shows petrographic characteristics of alkaline

magmas (Gargiulo, 2005) in these outcrops.

The basaltic rocks have amygdaloid (less than 2cm long) structure and were broke

through by hydraulic fractures infilled by successive events of zeolites and/or other secondary

minerals crystallization. The volcanic breccias were also cemented by zeolites. The zeolites in all

these domains are: mordenita, chabazita, heulandita, natrolita and analcima that were identified

by their morphology, optical properties and by XRD, SEM and EDS methods. Other secondary

minerals are: pumpellyite, albite, laumontite, chlorite/smectite (C/S) mixed-layer, smectite, white

micas, chalcedony, hematite and iddingsite.

Similar alkaline zeolites association has been found by Vattuone et al. (2001)

northeastward of the study area, where it was related to a very low temperature (150º - 200ºC)

hydrothermal event.

PETROGRAPHY AND MINERALOGY

The amygdales in basalts have concentric filling with hematite in the edges and, toward

the center, progressively crystallized fibrous pumpellyite, colloform banding of white micas and

spherulitic chalcedony. The pumpellyite is often partially or totally replaced by smectite. The

largest amygdales have the complete sequence of crystallization, with fibrous mordenite and

idiomorphic cubic chabazite or idiomorphic icositetrahedral crystals of analcime filling all the

space in the centre of the cavity. In some of them, zeolites are absent but massive calcite is found

instead. The veins have been symmetrically infilled by almost the same assemblages of the

smaller amygdales. As in those, the zeolites have no space to crystallize. The volcanic breccias

were cemented by the assemblage of white mica, heulandite, needle-shaped natrolite (with

parallel/radiated arrangement) and analcime. Massive calcite can also occur as a final product.

The primary relictic minerals in basalts are: fresh clinopyroxene, altered plagioclase, scarce and

altered olivine, lamprobolite and magnetite. Plagioclase microphenocrystals are partially replaced

by albite + laumontite + white mica; albite + pumpellyite + C/S; albite + smectite or albite +

calcite. Olivine microphenocrystals are partial or totally pseudomorphically replaced by hematite

with iddingsite in the edges and bowlingite or pumpellyite toward the center of the

microphenocrystals. In some of them pumpellyite is partially replaced by smectite.

DISCUSSION

The assemblage of laumontite + pumpellyite + albite + C/S is typical of the zeolite facies

and indicates that the highest temperature reached was between 200° and 260ºC and the pressure

was lower than 6Kbar (Frey et al. 1991). In amygdales and cement of the breccias, mordenita,

chabazita, heulandite, natrolita, analcime (+ white mica ± smectite) crystallized, suggesting that

the temperature was lower than 200ºC. The aCO2 of the system was variable and became more

important at the final stage of the crystallization sequence, when has only crystallized massive

calcite. The presence of hematite indicates a system with high ƒO2 conditions.
