Text Description:	Blocky, rubbly outcrop of Dome D at the top of Site 12. Fine grained, weakly porphyritic with a matrix of symplectic feldspar and quartz. Phenocrysts of feldspar are present. There are several small blue, green and brown microphenocrysts present. Electron microprobe analysis indicates that color is a poor guide to determining what the microphenocrysts are. The EMP analyses are amphibole-like, arfvedsonite? and astrophyllite?. Apatite needles are also present.
