Dikes/Intrusions

The light-colored bands of rock cutting across the monzogranite were formed when molten magma pushed through joints in the rock. Being of a harder material (aplite or pegmatite), dikes as they are called, are more resistant to erosion and weathering, and tend to protrude above the bedrock as low walls.
