Summary

[edit]
Description

"Marinace Green Granite" - metaconglomerate from the Precambrian of Brazil. (~21.5 cm across)

This attractive decorative stone is a greenish, Precambrian-aged, polymict metaconglomerate from Bahia State in eastern Brazil. Available clast lithology compilations indicate that this rock is dominated by pebbles and granules of granite, gneiss, and mafic igneous rocks. Some clasts have been partially epidotized. The matrix is a pleasant greenish color, dominated by epidote, quartz, and tremolite.
