【摘要】 通过1∶5万区域地质矿产调查,对天山西段北缘地区的岩浆岩岩体作了研究。主要通过矿物地质特征,对冰达坂一带12个岩体的特征及其分布进行了总结,得出该区岩体在空间分布上具有明显的分带特征。并对各个岩体的稀土元素配分曲线进行了简要分析,大部分为轻稀土富集型,曲线右倾,具中等δ(Eu)负异常。更多还原

【Abstract】 This paper represents the character and distribution of the Bindaban magmatic rocks acquired from the(1∶50000) regional survey in the west Tianshan mountains.12 magmatic bodies outcropped in the studied area display obviously spacial zoning according as their mineral,petrology and geology features.The REE features of the all rocks are described.Most of them are LREE-rich type with moderate Eu negative abnormity.更多还原
