About this document

Geochemical Homogeneity of Cerro Galán by Rene Yasmany Cobas Torres is a document available to read on EtoBox.

This study analyzes samples from the Cerro Galán caldera in NW Argentina to understand the long-term evolution of its large silicic magmatic system. The system repeatedly erupted rhyodacitic magmas over 3.5 million years, with nearly identical geochemistry. Two main clast types are found - dominant "white" pumice and subordinate "grey" pumice. Geochemical modeling suggests the ignimbrites crystallized from the same parental "grey" magma, with minor variations explained by differing crystal fractionation amo
