Las rocas de edad Permica objeto de este trabajo, se extienden espacialmente, en dos areas diferentes sobre el flanco oriental de la Cordillera Central en el departamento del Huila: Un primer afloramiento se localiza al occidente del municipio de Pacarni cerca al corregimiento de Rio Chiquito-Huila, donde se presenta un bloque de granofels con contactos fallados y un cuerpo de granito rosado intruido por charnoquitas de la Cuarzomonzodiorita de Paez (plancha geologica 344--Tesalia, Marquinez et al.

Presenta sectores con bandas decimetricas definidas y difusas, donde el contenido de minerales maficos y felsicos varia de una banda a otra, que corresponden a neises y granofels cuarzo--feldespaticos con anfibol y biotita o el equivalente metaigneo como metatonalitas, metacuarzodioritas y metagranodioritas (FIGURA 2C).
At higher regional metamorphic grade and around the margins of plutons, the more pelitic beds are composed of andalusite-garnet-sillimanite schist, granofels, and migmatite.

El Complejo Migmatitico de Mitu se subdivide en la plancha 443 en tres unidades que se denominan: Monzogranito de Mitu, Granofels de Pringamosa y Neis del Yi, esta separacion esta soportada en las caracteristicas macroscopicas, microscopicas y quimicas de las rocas que las componen y corresponden a unidades cartografiables.

As metamorphic grade increases, the Halifax Formation is characterized by the development of porphyroblastic staurolite and andalusite granofels and schist.
The northern margin of the pluton has an irregular outline due to the abundance of garnet-sillimanite granofels and schist xenoliths.
Overlying the basal quartzite and conglomerate, the Megunticook Formation is mainly comprised of quartz-mica schist, typically containing small garnet, calc-silicate rocks, chiastolitic quartz-biotite schist, and thin bedded quartzite and schistose quartz-plagioclase-mica granofels (Berry and Osberg 1989; Tucker et at.
