它温查汉西铁多金属矿床是东昆仑祁漫塔格成矿带新发现的又一典型矽卡岩型矿床,与成矿密切相关的花岗闪长斑岩和二长花岗斑岩成岩时代分别为236.0±2.3 Ma和229.9±2.0 Ma。二者均为弱过铝质高钾钙碱性系列,成因类型分别属于Ⅰ型和A型;二者稀土元素配分表现为富LREE、贫HREE以及中等Eu负异常的特征,微量元素具有Th、U、K、Zr、Hf相对富集和Nb、Ta、Ti、Sr、Ba相对亏损的特征。花岗闪长斑岩和二长花岗斑岩形成于晚古生代—早中生代构造—岩浆旋回的碰撞—后碰撞转化阶段,与区域上的大规模幔源岩浆底侵及壳—幔岩浆混合作用有关,从形成花岗闪长斑岩到二长花岗斑岩过程中地壳具有由厚减薄的趋势。 The Wensha Hanxi iron polymetallic deposit is another typical skarn type deposit newly discovered in the Qimantag metallogenic belt of East Kunlun. The granodiorite porphyry and the monzonitic granite porphyry are closely related to metallogenesis Diagenetic ages were 236.0 ± 2.3 Ma and 229.9 ± 2.0 Ma, respectively. Both of them are weakly perovskite high-K calc-alkaline series, and their genetic types belong to type Ⅰ and type A, respectively. The REEs are characterized by rich LREE, poor HREE and moderate Eu negative anomalies. The trace elements have Th, U, K, Zr, Hf relative enrichment and Nb, Ta, Ti, Sr, Ba relative loss characteristics. The granodiorite porphyrite and the monzonitic granite porphyry were formed during the Late Paleozoic-Early Mesozoic tectonic-magmatic cycle during the collision-post-collision transformation and mixed with the large-scale mantle-derived magmatic emplacement and crust-mantle magma in the area , The crust has a tendency to be thinned by thickening from the granodiorite porphyry to the two-granite porphyry.
