ophitic

Of or relating to ophite.

Having a texture composed of lath-shaped plagioclase feldspar crystals in a matrix of pyroxene crystals.

An epithet applied by various lithologists to a structure, especially characteristic of certain diabases and dolerites, in which the augitic constituent is separated into thin plates by interposed lath-shaped crystals of plagioclase, although the identity of the augite crystal is not lost, as is shown by the similar optic orientation of the separated portions.
