X-ray color maps of the zoned garnets from silgará formation metamorphic rocks,santandermassif, eastern cordillera (colombia)

The metamorphic rocks of the Lower Paleozoic Silgará Formation of the Santander Massif, Eastern Cordillera (Colombia), were affected by a Barrovian-type metamorphism under low to high temperature and medium pressure conditions. These rocks contain garnet porphyroblasts, which show several kinds of c...
