Here's an example of a similar texture in Apollo rock 60017: http://ser.sese.asu.edu/cgi-bin/DPSC_Data.pl?search=1&rock=60017&piece=& size=&slide=&coments= Anyone recall seeing another meteorite with that texture? The following meteorites are described as having similar textures: NWA 1000, a highly shocked eucrite: "subophitic and slightly variolitic (fan-spherulitic) texture with laths of plagioclase (up to 4 mm long) and pyroxene (up to 5 mm)." NWA 1240, an anomalous, unbrecciated eucrite: "achondrite consisting of skeletal low-Ca pyroxene phenocrysts in a variolitic (fan-spherulitic) mesostasis of pyroxenes, plagioclase,...The rock resembles some Apollo 15 pigeonite basalts but mineral and bulk rock compositions indicate a relationship to eucrites."
