Figure F298 (continued). I. Xenoliths of the host sheeted dikes (fine-grained gabbronorite) (Section 312-1256D-230R-1 [Piece 8, 49–83 cm]). J. Contact of a fine-grained granoblastic rock entrained in the host gabbro (Thin Section 107; Sample 312-1256D-230R-1, 49–54 cm). K. Contact of a fine-grained granoblastic rock included in the host gabbro (Section 312-1256D-230R-1, 59–63 cm). L. Contact in K, showing concentration of oxides along the boundary and weak shape-preferred orientation of plagioclase crystals in the host gabbro around the boundary (left = plane-polarized light; right = cross-polarized light).
