Basalt: Mineral information, data and localities.

A mafite or basaltoid containing mostly calcic plagioclase, clinopyroxene +/- olivine, orthopyroxene, foids, oxides and rarely quartz. A general term for fine-grained, mafic (dark-colored) igneous rocks, commonly extrusive (volcanic) but locally intrusive (e.g., as dikes or pipes), composed chiefly of plagioclase and clinopyroxene; the fine-grained equivalent of gabbro.

Basalt is the result of partial melting of meteoritic material (Earth is made of a huge mass of meteorites!), so it forms on other terrestrial planets (which also accumulated from meteorites) as well as Earth, making basalt the “mother liquor” of volcanoes on terrestrial planets. It is found all over Earth, but especially under the oceans and in other areas where Earth’s crust is thin.

Dike (geology) Wikipedia

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 contiguous mass of rock. Clastic dikes are formed when sediment fills a pre-existing crack.
