Geochemistry of volcanic series of the Los Azufres geothermal field (México)

The Los Azufres Geothermal Field (Michoacan, Mexico) is located in the Trans-Mexican Volcanic Belt (MVB). The volcanic series consists of a pile of andesitic flows, overlained by rhyolitic and dacitic domes and flows. Most of the rocks sampled from surface outcrops are of Late Pleistocene age. The m...

Sumario:The Los Azufres Geothermal Field (Michoacan, Mexico) is located in the Trans-Mexican Volcanic Belt (MVB). The volcanic series consists of a pile of andesitic flows, overlained by rhyolitic and dacitic domes and flows. Most of the rocks sampled from surface outcrops are of Late Pleistocene age. The mineralogy and the calcalkaline nature of the whole series show a good coherence with other suites of the MVB volcanoes, but an análisis of the magmatic chemical trends indicates complex and ambiguous relationships between the studied units.
