Figure F296. Textural bands and patches in gabbros. A. Textural banding is defined by a layer that continues from one end to the other end of a piece and has different grain size or texture (interval 312-1256D-223R-2, 35–55 cm). B. Textural and compositional patch wherein the plagioclase-rich domains are granoblastic and surrounded by pyroxene-rich ophitic domains (interval 312-1256D-214R-3, 5–13 cm). C. Thin section of the same piece (interval 312-1256D-214R-3, 6–10 cm) (cross-polarized light). The darker area in B consists of oikocrysts of clinopyroxenes. D. Textural patches and veins with white alteration zone in Section 312-1256D-220R-1 (Piece 3, 8–23 cm). E. Leucocratic magmatic patches cut by green veins with white alteration zone (whole thin section, Sample 312-1256D-220R-1, 24–29 cm).
