Figure F91. Photomicrograph showing vermicular spinel in harzburgite with protogranular texture (Sample 209-1270D-3R-1, 94–97 cm) (cross-polarized and reflected light: blue + dark gray filters; field of view = 2.75 mm; image 1270D_029). A similar texture is present in Sample 209-1270C-1R-1, 72–75 cm. This texture is characteristic of harzburgite that was not affected by intrusion and deformation of magmatic veins in Holes 1270C and 1270D. This texture suggests that the harzburgite has not experienced significant ductile deformation since formation of the protogranular orthopyroxene and vermicular spinel.
