Journal Article: Petrographic Study And Preliminary Conceptual Model Of The Lxtlan De Los Hervores Geothermal Zone, Michoacan, Mexico

Abstract
Petrographic studies of cuttings from the shallow well lxtlan 2, drilled in the lxtlan de los Hervores geothermal zone, State of Michoacan, Mexico, at a maximum depth of 159 meters, together with results of previous exploration studies, allow to delineate a preliminary conceptual model of the probable geothermal system. It is formed by a wide-fracture zone system, with low topographic relief and shallow water level. Its hydrothermal fluids are of sodium-chloride type, neutral pH, silica oversaturated in the discharge and with temperatures between 125 and 225 T, based on the geothermometry and the hydrothermal mineral assemblage encountered in the well. The assemblage of laumontite + quartz + calcite + chlorite/smectite + pyrite is typical for the zeolitic facies, beneath of which it is possible to encounter the epidote-wairakite facies, with higher temperatures. The favorable conditions of the zone allow to recommend continuation of exploration in the same.
