| 文章介绍了东秦岭﹙河南段﹚钼矿床区域地质背景,重点分析了形成钼矿床必要的区域地球物理、地球化学、地层、构造、岩浆岩及成矿时代方面的特征,总结出钼矿床产于区域地球物理和地球化学异常部位,前寒武纪的太华群、熊耳群、官道口群、栾川群为4个富钼地层,前燕山期的北西西向断裂构造与燕山期北北东向断裂构造的交叉部位有利于燕山期小岩体的侵位和钼矿床的产出,燕山期中酸性小岩体与钼矿床具有时空上的一致性,该区钼矿床成矿时代主要为中元古代熊耳期和中生代燕山期,集中于(1884±210)Ma～(1352.95±27.06)Ma和(145±2.2)Ma～(106±2.1)Ma两个时段。 |
| 英文摘要: |
| It was introduced that regional geological setting of molybdenum deposit in the East Qinling orogenic belt (Henan section)in this paper, focusing on regional geophysical, geochemical, formation, ore-controlling structure, magmatic rocks and geochronology of the genesis of molybdenum deposit. Comprehensive summary regional geophysical and geochemical anomalies where molybdenum deposit generate:Taihua group, Xiong’er group, Guandaokou group and Luanchuan group. The crosss where the NW faults and the Mesozoic NNE faults occurred, are conducive to magma intrusion and the genesis of molybdenum deposit. The time and space of molybdenum deposit consistent with the Mesozoic intrusion. The mineralogenetic epoch of the East Qinling orogenic belt are from the Proterozoic and Mesozoic era, focusing on 1880～1350 Ma and 145～106Ma. |
