The study of fluid inclusions trapped in minerals of the Funtana Raminosa ore district permit reconstruction of the quite complex history of thermal metamorphic and hydrothermal events that preceded and accompanied ore deposition. On this basis, we have recognized a first thermal metamorphic, isochemical event, which produced garnet-pyroxene skarns in the Silurian rocks, followed by a long-lasting hydrothermal circulation. The latter caused the retrocession of anhydrous skarn parageneses, the ore deposition and the intricate relationships existing among the different alteration assemblages that affected magmatites and surrounding rocks in the area.

Abstract

The study of fluid inclusions trapped in minerals of the Funtana Raminosa ore district permit reconstruction of the quite complex history of thermal metamorphic and hydrothermal events that preceded and accompanied ore deposition. On this basis, we have recognized a first thermal metamorphic, isochemical event, which produced garnet-pyroxene skarns in the Silurian rocks, followed by a long-lasting hydrothermal circulation. The latter caused the retrocession of anhydrous skarn parageneses, the ore deposition and the intricate relationships existing among the different alteration assemblages that affected magmatites and surrounding rocks in the area.
