| 摘 要： | 位于华北克拉通北缘的西拉沐伦成矿带内花岗岩浆活动及钼矿化发育,带内主要成矿侵入体岩石类型包括二长花岗岩、斑状花岗岩、花岗斑岩及流纹斑岩,这些岩石属于高钾钙碱性和钾玄岩系列,岩浆源区为古老下地壳和新生地壳。这些侵入体形成于早—中三叠世、晚侏罗世及早白垩世。带内钼矿床包括斑岩型、石英脉型、云英岩型和火山-次火山热液型4种类型,以斑岩型矿床最为发育。带内钼矿床形成时代与相关侵入岩时代一致,也形成于早—中三叠世、晚侏罗世及早白垩世,以早白垩世钼矿床最为发育。3期成岩成矿作用分别形成于华北板块与西伯利亚板块同碰撞至后碰撞构造环境、古太平洋板块向欧亚大陆俯冲的构造环境和中国东部岩石圈减薄构造环境。

| Abstract: | Granitoids and molybdenum ore deposits or ore spots are well developed in the Xilamulun metallogenic belt located on the northern margin of the North China craton.The ore-bearing intrusive rocks include monozogranite,porphyritic granite,granite porphyry and rhyolite porphyry,which belong to the high-K calc-alkaline and shoshonite series.The rock-forming materials were derived from the lower crust and juvenile crust.These granitic intrusive rocks were formed in Early-Middle Triassic,Late Jurassic and Early C... |
