In geology, a dike or dyke 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 contiguous mass of rock.

Urk was then and is still today a fishing community and it served as a natural construction-island for both dikes as well as a base of operations for the later exploitation of the polder. Both ceased to be islands: Urk on 3 October 1939, when the dike reaching from Lemmer was closed and Schokland when the surrounding water was consequently drained.
