Abstract

Precise determination of about 40 elemental abundances in 10 chondrites from China, which are Ningqiang CV3; Wuan H6; Qingzhen EH3; Suizhou L6; Zaoyang H5; Nantong H6; Zhaodong L4; Guangnan L6; Dontai LL6; Nan Yang Pao L6, are carried out by Instrumental Neutron Activation Analysis (INAA). The fractionation of all classes of chondrites relative to Cl tends to increase with the elemental volatility. The fractionation factors of REErelative to that of the type 1 carbonaceous chondrite are as follows: enstatite 0.67; oli-vine bronzite 0.78; hypersthene 0.83; type 2 carbonaceous (Murchison) 1.12; type 3 carbonaceous 1.29, thus showing a tendency to decrease in the order of C3, C2, C1, L, H, Egroups. Ningqian Chondrit is an anomalous CVchondrite containing a low abundances oFbulk refractory lithophiles.
