Structure:
Green Sea granite includes feldspar minerals and quartz. Feldspars are medium grained and they appear also up to 2-4 centimeter ovoid crystals wit bright greenish grey shine. Quartz is light blue in colour. The amount of quartz varies from 5-20%. Structure has no orientation. Te granite is very suitable to dimensional stone production. Deposit is even coloured and fracture distance is big enough to quarry large blocks.
