| 文章对大别山钼多金属成矿带矿床的分布、产出部位、矿床类型、围岩蚀变等地质特征进行了总结,通过对矿床矿石中硫、氧同位素的研究探讨了成矿物质的来源,认为该区钼多金属矿床成矿流体为岩浆水,硫是与岩浆作用有关的深源硫,成矿物质主要来源于下地壳重熔形成的中酸性岩浆岩。根据成矿带矿床地质特征和成矿物质来源探讨了矿床成因,进而对在该成矿带的找矿方向进行了分析,指出在大别山钼多金属成矿带应以寻找中、高温斑岩型钼矿床为主,成矿有利部位位于北西西向与近南北向断裂交汇部位上侵形成的燕山期深源浅成高硅富钾富钼的花岗斑岩体内、外接触带。 |

| The paper summarizes the distribution, spatial location, deposit type, and wall rock alteration of the deposits within the Dabie Mountain molybdenum polymetallic metallogenetic belt. Based on the study on sulfur, oxygen isotope of the ore deposit, the authors think that the metallogenetic fluid formed the molybdenum polymetallic deposit belongs to the magmatic water, the sulfur comes from the deep source related to magmatism, and the metallogenetic materials mainly come from intermediate-acid magmatic rocks which are remelted from the lower crust. Based on the geological characteristics and sources of ore-forming materials of the metallogenetic belt, the deposit genesis is discussed, and the prospecting targets in the metallogenetic belt are analyzed. The author propose that it should focus on prospecting the medium-high temperature porphyry type molybdenum deposit in the Dabie Mountain molybdenum polymetallic metallogenetic belt, the favorable mineralization areas are located in the inner and outer contact zones of Yanshanian hypabyssal granite porphyry with deep-source silica, high potassium and molybdenum, which intruded along the junction of NWW-trending and near-SN-trending faults. |
