摘要
苏吾切达坂南山东稀土矿,属新疆若羌县管辖,大地构造位置属阿尔金造山带,阿中微地块;成矿区带划分属阿尔金Fe-Au-RM-石棉-玉石-白云母矿带,是首次在该矿带发现稀土矿,矿区圈定稀土矿化蚀变带一条,以ΣERO≥5000×10^(-6)圈定矿体3条,含矿建造为似斑状二长花岗岩,主成矿元素为轻稀土元素,以La、Ce、Nd为主,成因类型为花岗岩型稀土矿,产出于消减带的活动陆缘弧-同碰撞构造环境,成矿时代为寒武-奥陶纪。
The suwuqiedaban South Shandong rare earth deposit is under the jurisdiction of Ruoqiang County,Xinjiang.Its geotectonic position belongs to Altyn orogenic belt and Altyn middle micro block.The metallogenic belt is divided into Altyn Fe Au RM asbestos jade Muscovite belt,It is the first time to discover rare earth ore in this ore belt.The ore district delineates one rare earth mineralization alteration belt and three orebodies withΣero≥5000×10^(-6).The ore bearing formation is porphyritic monzogranite,and the main metallogenic elements are light rare earth elements,mainly La,CE and Nd.The genetic type is granite type rare earth deposit,which occurs in the active continental margin arc syn collisional tectonic environment of subduction zone.The metallogenic age is Cambrian Ordovician Taoji.
