Petrography: (A. Irving, UWS and P. Carpenter, WUSL) This fresh specimen has a poikiloblastic texture with abundant very small olivine chadacrysts enclosed by larger low-Ca pyroxene oikocrysts. No recognizable chondrules are present. Accessory phase include sodic plagioclase, augite, taenite, kamacite, troilite and merrillite. Some thin dark shock veinlets are present.
岩石学:
(A. Irving, UWS 与 P. Carpenter, WUSL)本新标本具有斑状变晶纹理,包含大量极小的橄榄石晶核,被较大、低钙辉石包镶晶包裹。未观察到可辨认的球粒。微量组分包括钠长石、辉石、Taenite、KamAcite、Troilite 与 Merrillite。存在一些细薄的暗色冲击脉。
