Petrografía, geoquímica, cristaloquímica y características de los fluidos asociados a una sección del metamórfico alflorante en Tierra Caliente, Estados de México, Guerrero y Michoacán
Main Article Content
Abstract
The metamorphic sequence of Tierra Caliente is discussed with respect to petrographic, geochemical, crystallochemical and fluid inclusion data. These rocks originated from iIIite clay sediments and show a mature sedimentation. Their transformation tobiotite and muscovite suggests an epizonal metamorphism. This is confirmed by the crystallochemical and fluid inclusion data. The temperature ranges from 300° to 470°C and the pressures range from 2.5 to 4 Kbar; the composition of the carbonic fluid inclusions suggcsts that they originated from dispersed organic material in the clay fraction.
