n.
A rock consisting essentially of pyroxene.
n.
The change of pyroxene to amphibole by paramorphism.
n.
A common mineral occurring in monoclinic crystals, with a prismatic angle of nearly 90¡, and also in massive forms which are often laminated. It varies in color from white to dark green and black, and includes many varieties 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.
n.
An igneous rock consisting largely of chrysolite, with pyroxene and picotite (a variety of spinel containing chromium).
n.
A dark-colored, basic, igneous rock, composed essentially of pyroxene and a triclinic feldspar with magnetic iron. By many authors it is considered equivalent to a coarse-grained basalt.
n.
A greenish spotted porphyry, being a diabase whose pyroxene has been altered to uralite; -- first found in the Pyreness. So called from the colored spots which give it a mottled appearance.
n.
An orthorhombic mineral of the pyroxene group, of a grayish or greenish black color, often with a peculiar bronzelike luster (schiller) on the cleavage surface.
