Description
Photo 2: View toward the northeast of an approximately 1.5 meter wide, vertically dipping, porphyritic diabase dike cross-cutting layered metamorphic rocks of the Bucksport Formation (Sb). Diabase such as this represents the youngest rock type in the quadrangle (~200 million years old) and formed when hot silica-poor magma flowed rapidly through cracks in the surrounding older rocks and then solidified quickly. The locations of additional smaller dikes are shown on the map with red symbols. South of New Harbor, Bristol.
