Description
Photo 1: Contact of the Christmas Cove diabase dike (J2cc) on the right with previously deformed and metamorphosed biotite gneiss on the left. Diabase represents the youngest rock type in the quadrangle (~200 million years old) and formed when hot silica-poor magma flowed through cracks in the surrounding older rocks and then solidified quickly. This particular dike, the largest in the region (McHone and others, 2014), is discontinuously exposed across the quadrangle. The locations of additional smaller diabase dikes are shown on the map with red symbols. Off Birch Island Lane, Georgetown.
