Figure F2. Photomicrograph of spinifex-textured xenolith in sample 142421. Larger, randomly oriented blades are olivine. The triangular spaces between olivines are occupied by radiating plates of pyroxene, with interstitial plagioclase laths that in places protrude into tiny miarolitic cavities. Large black grain is pyrite; others are ilmenite and chrome spinel. Width of view = 5.0 mm; ordinary transmitted light.
