Caracterización de las rocas metamórficas localizadas entre el alto de Boquerón y el corregimiento de Palmitas, Antioquia

Abstract

The tectonic evolution of Colombia is marked by collision, subduction and obduction events that developed between the Paleozoic and Cenozoic. These events were building what is now the western margin of the Northern Andes. The continuous tectonic dynamism of this western region has resulted in compositional, geochemical and petrographic changes in the metamorphic rocks that outcrop in the Central Cordillera of Colombia. The main objective of this research is to characterize the metamorphic rocks that outcrop between the Alto de Boquerón and Palmitas, between kilometer 22 to 27 of the San Jerónimo - Medellín road, which are part of the Ayurá - Montebello Group, and that present geochemical, geochronological, petrographic and structural characteristics of high complexity and great importance in the construction of the regional geological framework of the country.
