Cala Grande, Monte Argentario, Provincia di Grosseto, Toscana, Italia


The central sector of Cala Grande consists of rocks of the ophiolitic unit.

In particular, the area below Via Panoramica shows a variety of metasedimentary rocks in association with metabasites. The metasediments include pelitic material, hematitic chert, radiolarite, calcareous beds, graded beds of mafic detritus, and breccias containing a mixture of sedimentary and mafic fragments. Blueschist facies metamorphism is evident from mineral assemblages observed in the clastic rocks that contain gabbro-derived detritus, and from calcareous beds containing sodic amphibole (“blue marble”), and locally lawsonite. The range of metamorphic minerals in the gabbro-derived clastic beds is largely the same as in the metagabbros proper [see: http://www.mindat.org/loc-266493.html].
