WebMay 17, 2015 · These are basalts with columnar joints. Basalt is an igneous rock that forms when magma (liquid + crystals) erupts onto the surface as a lava flow or gets injected into cooler shallow crust and forms an intrusive dike or sill. Because basalt cools quickly, basalt commonly contains glass as well as crystals.
