摘要
稀有金属是我国重要的战略矿产资源之一。西南天山发育一条长近1500 km的碱性岩带,近年来发现了波孜果尔、巴什苏洪等多个稀有金属矿床。这些稀有金属矿床都与A型富碱花岗岩有成因关系。巴什苏洪碱性花岗岩中的稀土总量较高,∑REE变化范围为571.22×10-6~1234.78×10-6,轻稀土元素相对于重稀土元素富集,具有明显的负Eu异常。通过对巴什苏洪富碱花岗岩稀有金属的含矿性研究,认为该矿床具有形成大型矿床的潜力;同时认为西南天山碱性岩及富碱花岗岩是稀有稀土矿产的重要找矿勘查方向,尤其要加强深部的勘查工作。
Rare metals is one of kind important strategic mineral resources in China.In recent years,Bozgol,Bashisuhong and other rare metal deposits have been discovered in an alkaline rock belt nearly extending 1500 km in the southwestern Tianshan mountains.These rare metal deposits are all genetically related to A-type alkali-rich granite.The total REE content in Bashisuhong alkali-rich granite is relatively higher with variation range around 571.22×10-6~1234.78×10-6,and LREE is enriched relative to HREE with Eu negative anormalies.Based on the study of ore-bearing properties of rare metals in Bashisuhong alkali rich granite,it is considered that the deposit has the potential to be indentified as a large-scale deposit.At the same time,it is considered that alkaline rocks and alkali-rich granites in southwest Tianshan mountains are important prospecting and exploration target for rare and rare earth minerals,especially deep exploration should be strengthened.
