摘要
丹巴地区大地构造位于松潘—甘孜造山带中的丹巴弧形构造岩片之上,含矿镁铁-超镁铁岩体围绕杨柳坪穹隆构造分布。侵入岩体遭受不同程度的变质,岩体主要由含橄榄石的蛇纹岩、滑石岩、辉石岩和辉长岩组成,各岩相带之间呈渐变过渡关系。矿石自然类型主要为原生硫化物型镍矿石。文中分析了杨柳坪镍矿床所处的特殊成矿地质背景、矿床地质特征,并对矿床成因进行了分析。
The tectonic structure of danba area is located above the danba arcuate tectonic sheet in songpan-ganzi orogenic belt.The intrusive rock body suffers from metamorphism of different degrees,and the rock body is mainly composed of olivine serpentinite,talcite,pyroxenite and gabbro.The natural type of ore is mainly primary sulfide nickel ore.This paper analyzes the special metallogenic geological background and geological characteristics of yangliuping nickel deposit,and analyzes the genesis of the deposit.
