Figure F3. Typical occurrence of clinopyroxene (Cpx) and orthopyroxene (Opx) in gabbronorite (Thin Section 3; Sample 345-U1415E-1R-1, 41–43 cm [Piece 5]). Both minerals form anhedral crystals in the interstices of the plagioclase framework. Orthopyroxene is generally larger than clinopyroxene and tends to form a poikilitic texture. A. Plane-polarized light. B. Under crossed polars.
