摘　　要：采用同步辐射X荧光技术对格尔柯金矿花岗闪长岩中的副矿物——磷灰石进行了分析。磷灰石成分分析显示原始岩浆属铁镁质I型花岗岩,具有富集轻稀土、Nd消耗的特征,流体包体成分分析显示岩浆热液中含有Fe、Mn和微量的As、Co、Zn。In this article, SRXRF technique was applied on apatite, one of accessory minerals from granitic diorite,Ge＇erke Gold Deposit. Chemical composition of the crystal and its fluid inclusion was analysized. Apatite composition shows that the original magma belongs to mafic I-type granites with high light rare earth elements and Nd depletion characteristics. Containting Fe and Mn and trace As, Co, Zn the fluid inclusion, reflects hydrothermal liquids from magma as one of material resources of gold mineralization.
