Mineralogy and geochemistry of a dioritic intrusive rock in central Mexico
Abstract
In the center of Mexico (Hidalgo state), a horseshoe-shaped structure named Panales is located, 7 km in diameter, which exhibits in its center a small intrusive (Cerro Siete Minas of 0.5 km2 outcrop), whose age it has been considered as of the lower Tertiary. The mineralogical and geochemical characterization of the intrusive shows that it is an augite-enstatite diorite, with a moderate composition of potassium and sodium, metalluminous ((A / CNK = 0.95) and chalcoalkaline. The geobarometric and microthermometric data of clinopyroxene and plagioclase suggest that the depth of formation of this intrusive was between 11-12.5 km (3.3-3.8 kbars), and 900-800 ° C, later re-equilibrated temperature values indicate 500-600 ° C. It is suggested that the intrusive may represent part of the plutonic root of a collapsing volcanic structure emplaced in this sector of the Trans-Mexican Volcanic Belt.
