Figure F48. Photographs showing textures from the lower impregnation horizon in Hole 1271B. These textures resemble textures in experiments on partially molten mixtures of olivine plus basalt. A. Close-up photograph of a large olivine crystal surrounded by impregnating material that contains rounded spinel grains (interval 209-1271B-19R1, 125–130 cm). B. Close-up photograph of interstitial impregnation textures and patchy, veinlike impregnation textures, indicating that multiple liquids of differing composition impregnated this dunite (interval 209-1271B-19R-1, 10
