Dolerite

From SCWiki

Dolerite is an igneous rock formed below the Earth's surface, a form of basalt, containing relatively little silica (mafic in composition). Dolerite is a medium-grained (hypabyssal) basalt and forms in shallow intrusions, such as dykes, which cut across the rock strata, and sills, which push between beds of sedimentary rock. When exposed at the surface, dolerite weathers into spherical lumps.

Climbing on Dolerite

Much of the Dolerite climbing in the cental belt is on quarried dolerite.
