摘要
作者运用仪器中子活化分析法(INAA)和放射化学中子活化分析法(RNAA)分析测定了吉林陨石(H群)高温高压实验产物金属相中元素Ni,Co,Cu,Cr,Mn,Ga,Ir,Au,As,Ru,Pd,O_s和P_t的含量,根据这些结果讨论了母体热变质和熔融作用对球粒陨石金属相组成的影响,并提出了元素熔融贫化因子f来定量描述这些影响的大小。
The concentrations of Ni, Co, Cu, Cr, Mn, Ga, Ir, Au, As, Ru, Pd, Os, and Pt in the metal phase of the Jilin chondrite at high temperature and high pressure have been determined by INAA and RNAA. In terms of the results, the compositional variation of chondritic metal phase and the factors governing its formation are discussed and the factor-elemental melting dilution (f), which represents quantitatively the range of compositional variation is also presented in this paper.
