| 摘 要： | 通过对造岩矿物、岩石化学和铂族元素等信息的综合分析，认为金川岩体的母岩浆属拉斑玄武质苦橄岩浆，是地幔橄榄岩经３３％部分熔融的产物；硫、钕、锶、氧等同位素资料说明岩浆源区可能在上地幔低速层底部，属富集型地幔

| Abstract: | Through synthetical formation analyses of rock forming minerals, lithoche mistry and platinoids,the parent magma of Jinchuan rock body belonged to tholeiitic picrite one,which was produced by mantle peridotite was part corroded(33%).According to data of S,Nd,Sr and O isotopes,magmatic source area probably was the bottom of low velocity layer of upper mantle that belonged to enriched type mantle. |
