웹Volcanic Neck. Named for its resemblance to the silhouette of a sailing ship, Ship Rock is a volcanic neck located where the main feeder pipe for a larger volcano was once located. The wall-like rock feature radiating outward from the volcanic neck is a dike (see below). Image copyright iStockphoto / Emre Corbaci. A dike or dyke, in geological usage, is a sheet of rock that is formed in a fracture of a pre-existing rock body. Dikes can be either magmatic or sedimentary in origin. Magmatic dikes form when magma flows into a crack then solidifies as a sheet intrusion, either cutting across layers of rock or through a … 더 보기 A magmatic dike is a sheet of igneous rock that cuts across older rock beds.
