A new approach on the tectonometamorphic mechanisms associated with p–t paths of the barrovian-type silgará formation at the central santander massif, colombian andes

Metamorphic pressure and temperature trajectories are generally used as tools to interpret the tectonic history ofdeformed belts of rocks that record past activity along active plate margins. The pre-Devonian metamorphic sequenceof the Silgará Formation forms part of the ancient basement of the cent...
