摘　　要：在地球化学系统中,元素的亲合性是制约元素地球化学行为的基本属性,而赋存状态则反映元素质的属性。对黔西基性玄武岩原岩与流体包体中Pt、Pd的赋存状态进行研究,结果说明了利用元素亲合性对指导其赋存状态查定的重要性,同时表明了研究该地区玄武岩中同生流体包体中铂族元素对重演古流体中元素迁移与富集具有重要的理论与实际意义。In a geochemical system, the affinity of an element controls its geochemical behaviors while its occurrence state represents its nature. The abundance and occurrence state of an element shows its difference in affinity and could provide important information for the geochemistry system and for the behaviors of an element in the system. The occurrences states of Pt and Pd in the parental rocks and in the fluid inclusions of the Western Guizhou Province basalt are studied. The result of this study shows the importance of determing the occurrence state of an element using its affinity, revealing that the PGE can be used in studying the migration and enrichment of elements in syngenetic fluid of the basalts.
