Punta Maria's white limestone rock

As I mentioned in the previous post, the white beach of Punta Maria comes from the disintegration (or weathering as it is called in geology) of the white limestone rock. The photo shows that wave action has already dissolved or removed a large part of this large limestone rock. The softest portion of the rock was the first to be removed and the debris accumulated as white beach sand. If you visit the Songco beach, it is black colored because of the dark color of the igneous (volcanic) rocks from which the beach sand and gravels were derived.
