Material assimilation in a shallow diapiric forceful intrusion: evidence from microstructures and csd analysis in a porphyritic intrusive body, “la línea” tunnel, central cordillera, colombia

The contact between the unit Porphyry Andesite and the Cajamarca Group is observed in the "Túnel de la Linea" section. The integration of petrographic, geochemical and textural (crystal size distribution, CSD) analysis allows description of physical and chemical processes that took place i...
