Figure F57. A partially resorbed interstitial clinopyroxene crystal (middle left) in a plagioclase-rich xenolith in Sample 192-1183A-57R-3 (Piece 2, 15-17 cm), Unit 5B. Other interstices are filled with quenched glass (now devitrified and altered to clay). A. Plane-polarized light. B. Crossed polars. (Field of view = 2.8 mm; photomicrograph ID#s 1183A_13 and 1183A
