Chemical compositions and cassfication of Grove Mountains (GRV) 98003 and other Chinese iron meteorites
摘要
Abstract
Concentrations of Cr, Co, Ni, Cu, Ga, Ge, As, Sb, W, Re, Ir, Pt and Au of two ungrouped iron meteorites, Grove Mountains (GRV) 98003 from Antarctica and Ujimqin, were measured using instrumental neutron activation analysis. According to the bulk chemistry, GRV 98003 is classified as a member of lAB group,and Ujimqin as a unique one of IAB iron meteorite complex. The elemental abundance pattern and correlation between elements (e. g. Ni-Au, Co-Au, As-Au, W-Au, Cu-Au, Sb-Au) of GRV 98003 are similar with those of NAW 468 (IAB), but significantly depleted in refractory siderophile elements (Re, It) and moderate volatile elements (Ga, Ge) relative to the latter. In addition, we reclassify Nantan (Ⅱ-ICD) as a member of IAB main group (MG) and Yongning (IA) as a unique iron meteorite related with IAB iron meteorite complex.关键词
