Dolerite is a type of volcanic rock that is commonly coarse-grained, dark-colored, and intermediate in composition between basalt and gabbro. It is also known as diabase in some regions. Dolerite is composed mainly of plagioclase feldspar, pyroxene, and sometimes olivine, and is often associated with other volcanic rocks such as basalt and rhyolite. It is commonly found in sills, dikes, and other intrusions, and is also occasionally found in volcanic plugs and lava flows. Dolerite is widely distributed around the world and has a variety of uses in construction, road building, and as a decorative stone.
