Figure F13 (continued) C. High-temperature microscopic vein (HTMV) along the grain boundary between plagioclase and clinopyroxene in olivine gabbro (Sample 176-735B-101R-1 [Piece 7, 106-108 cm]; cross-polarized light; field of view = 3.2 mm). The vein is running on the outer edge of the magmatic plagioclase grain. A very fine grained intergrowth of brown amphibole + orthopyroxene (Ig) was formed on the edge of the clinopyroxene contacted by the vein. In this figure, also shown is the intimate association of high-temperature microscopic veins and the interfingering clinopyroxene (IfIg). Ol = olivine, Cpx = Ca-rich clinopyroxene, Plag = plagioclase.
