Figure F4. Typical appearance of homogeneous equigranular orthopyroxene (Opx)-bearing olivine (Ol) gabbro in Unit II (Multitextured Layered Gabbro Series). A. Sample 345-U1415P-9R-2, 12–33 cm (Pieces 3, 4). B, C. Patchy distribution of two different lithologic domains which are distinguished by the amount of orthopyroxene, 0 in the left domain and 5% in the right domain, leading to the rock name “olivine gabbronorite” for the right domain (Thin Section 119; Sample 9R-2, 20–21 cm [Piece 3]). Cpx = clinopyroxene, Pl = plagioclase. B is under plane-polarized light; C is under crossed polars.
