新疆民丰县盼水河锑矿矿床地质特征及成因研究

Geological Characteristics and Genesis of Panshuihe Antimony Deposit in Minfeng County,Xinjiang

盼水河锑矿位于新疆民丰县境内,大地构造位置上处于秦-祁-昆中央造山带中段巴颜喀拉晚古生代-中生代边缘裂陷盆地内。区内构造-岩浆活动强烈,成矿受断裂构造控制明显。锑矿体主要赋存于二叠系黄羊岭组二段海相陆源碎屑岩地层中,分为2个主要矿体。矿床类型为典型的岩浆期后低温热液矿床,研究为以后在该地区寻找锑矿提供了科学依据。

Antimony deposit of Panshuihe is located in Minfeng County of Xinjiang.The tectonic position is seated in bayankala Late Paleozoic-Mesozoic marginal rift basin in the middle of Qin-Qi-Kun central orogenic belt.Tectono-magmatic activity is strong in the area and mineralization is obviously controlled by fault structure.Antimony ore body mainly occurs in the Marine terrigenous clastic rock strata of the second member of Permian Huangyangling Formation and it is divided into two main ore bodies.The deposit type is typical post-magmatic cryogenic hydrothermal deposit,which provides scientific basis for searching antimony deposits in this area.
