CATION SUBSTITUTIONS GOVERNING THE CHEMISTRY OF AMPHIBOLE IN THE SILGARÁ FORMATION METABASITES AT THE SOUTHWESTERN SANTANDER MASSIF
Amphibole-bearing parageneses from the Silgará Formation metabasites at the southwestern Santander Massif record evidence of prograding metamorphism. Optical and microprobe analyses, together with thermobarometric estimates on these rocks, show that the main variation in Ca-amphibole is the simultan...
