Abstract

Abstract

The concentrations of Fe, Ni, Co, Cu, Cr, Mn, Ga, Ge, Ir, Au and As in the metal phases of Jinlin (H₃), Xinyang (H₅), Zhaodong (L₅), Guangrao (L_6-5) and Dongtai (LL₆) ordinary chondrites in China are determined by instrumental neutron activation analysis, For each meteorite various metallic fractions were analyzed: <20 mesh, 20 -40 mesh, >40 mesh and so on. In terms of these results, the elemental distribution and fractional trends and the processes determining the composition of the metal phase are discussed.
