| 摘 要： | 陕西省华县金堆城钼矿床属典型的斑岩型钼矿床。矿体主要赋存在燕山期金堆城花岗斑岩体和中元古界熊耳群的火山岩中,其次为上元古界高山河组变质石英岩中;近东西向断裂构造与斜交东西构造线的平推剪切断裂所构成一个北西-南东向的"节理裂隙密集带",为矿质的富集提供了有利的空间。成矿受上述的地层岩性、构造、侵入岩因素的联合控制。

| Abstract: | Jinduicheng molybdenum deposit in Hua County, Shanxi Province is a typical porphyry molybdenum deposit. Ore bodies mainly occurred in Yanshan period in jinduicheng granite porphyry bodies and middle proterozoic Xionger Group of volcanic rock, followed by upper proterozoic Gaoshanhe group metaquartzite ; Nearly east-west fracture structure with oblique east-west tectonic line horizontal pushing shear fracture formed a northwest - southeast joint fissure concentrated beh, provides the advantageous space of mineral enrichment. Mineralization is jointly controlled by the stratum lithology, structure, intrusive rock. |
