See Areopagite.

Pertaining to, or like, augite; containing augite as a principal constituent; as, augitic rocks.

rieties differing in color and composition, as diopside, malacolite, salite, coccolite, augite, etc. They are all silicates of lime and magnesia with sometimes alumina and iron. Pyroxene is an essential constituent of many rocks, especially basic igneous rocks, as basalt, gabbro, etc.

lized, but generally massive with rhombohedral cleavage like calcite; -- called also dialogite.
