摘　　要：介绍了一种对陨石单矿物分离并进行中子活化分析的方法,解决了陨石学和宇宙化学研究中多年企图解决的困难。The separation of individual minerals from meteoritical polished sections and their instrumental neutron activation analysis (INAA) have been described. The trace element concentrations of oldhamite (CaS), niningerite (MgS), djerfisherite, troilite, and phases of A and B in some enstatite chondrites have successfully been analyzed by this method and the contamination with metal phase for these minerals have been discussed.

关 键 词：中子活化分析 陨石矿物 硫化物
