Andrew Alden/Flickr. Basalt is an extrusive or intrusive rock that makes up most of the world's oceanic crust. This specimen erupted from Kilauea volcano in 1960. Basalt is fine grained so the individual minerals are not visible, but they include pyroxene, plagioclase feldspar, and olivine.These minerals are visible in the coarse-grained, plutonic version of basalt called gabbro.
