Norite Wikipedia

Norite is a mafic intrusive igneous rock composed largely of the calciumrich plagioclase labradorite, orthopyroxene, and olivine. The name norite is derived from Norge, the Norwegian name for Norway. Norite also known as orthopyroxene gabbro. Norite may be essentially indistinguishable from gabbro without thin section
