Thermal modeling of pluton emplacement and associated contact metamorphism:parashi stock emplacement in the serranía de jarara (alta guajira, colombia)

In the northernmost portion of the Serrania de Jarara (Alta Guajira, Colombia), low - medium grade metamorphic rocks from the Etpana Metamorphic Suite were thermally affected by emplacement of a small calc-alkaline intrusion (Parashi Stock). Detailed petrographic analysis in collected rock samples a...
