摘要
通过与ＲＥＥ模式对比，介绍了贵金属（ＰＧＥ＋Ａｕ）配分模式的构筑方法和组成参数；并对包括地幔岩石、科马提岩和玄武岩在内的各种基性、超基性岩石的特征ＰＧＥ＋Ａｕ配分模式和贵金属分馏机制进行了综述；根据贵金属模式在岩石学和铜镍硫化物与ＰＧＥ矿床上的应用，阐明了成岩成矿过程中贵金属的地球化学指示剂意义。
As contrasted with REE patterns, the plotting methods and compositional parameters of noble metal patterns are stated in this paper. The charactristic PGE+Au patterns of various basic and ultrabasic rocks including mantle rocks, komatiites, and tholeiites as well as the fractionation mechanisms of noble metals are summerized. On the basis of applications of noble metal patterns in petrology and deposits of copper- nickel sulfide and PGE,the significance of noble metals as geochemical indicator in diagenetic and metallo-genie processes is clarified.
