Figure F23. Summary of core recovery and observations of segregation bands, grain size, degree of alteration, thin section sample locations, textures, and minerals from X-ray diffraction data for the upper igneous sill at Site 1276. Photomicrographs 2i, 13i, and 6i show the texture denoted in the texture column. Photomicrograph 4i shows the composition of a segregation band. The alteration is shown with gray shades, where dark gray is complete alteration and lighter shades are moderate. The recovery of the core is shown in red. Plag = plagioclase, cpx = clinopyroxene, mag = magnetite.
