Description
Photo 1: View towards the southwest of the northern contact of the Christmas Cove diabase dike (J2cc, darker colored rocks on the left) with the Bucksport Formation (Sb). At this location, the dike is about 80 feet wide and strikes approximately 075°. Diabase represents the youngest rock type in the quadrangle (~200 million years old). It formed when hot silica-poor magma flowed rapidly through cracks in the surrounding older rocks and then solidified. This particular dike, the largest in the region (McHone and others, 2014), can be traced across the quadrangle. The locations of numerous additional smaller dikes are shown on the map with red symbols. Christmas Cove, South Bristol.
