| 陕西省商洛市潘河钼矿床位于东秦岭钼矿带西南,赋矿地层为中元古界宽坪群。本文对潘河钼矿床矿体特征、矿石特征、围岩蚀变特征、1∶5万分散流异常与成矿、岩浆活动与成矿、环形构造与成矿、构造与成矿、矿床类型7个方面进行了系统总结和研究。潘河钼矿床与1∶5万分散流及环形构造套合较好。矿区岩体受北北东向断裂控制,与区域上矿床展布一致；潘河地区环形构造整体为北北东向展布,与区域上岩浆构造带的展布方向相同；成矿物质来源为隐伏的白岗岩体,主矿体明显受隐伏白岗岩体控制,其矿床类型为斑岩-矽卡岩型。该区北北东向上,1∶5万分散异常叠加环形构造和构造发育地区找矿潜力巨大。 |
| 英文摘要: |
| Panhe molybdenum deposit is located in the western part of Southwest Qinling molybdenum ore belt. The host strata of the deposit is Middle proterozoic kuanping group. In this paper,the geological characteristics of molybdenum deposit are systematically stated and studied from seven aspect:the ore body characteristics, ore characteristics, wallrock alteration characteristics, the relationship between 1∶50,000 dispersion train anomalies and mineralization, the relationship between magmatism and mineralization, the relationship between circular structure and mineralization,the relationship between tectonic activity and mineralization,the type of ore deposit. The Panhe molybdenum deposit is well interbedded with 1∶50,000 dispersion train anomalies and circular structure. The Magmatic rocks in the mining area is controlled by NNE trending fault, which is consistent with the distribution of ore deposits in the region. The circular structure in Panhe area is distributed in the NNE direction, which is the same as that of the magmatic tectonic belt. The main ore body is obviously controlled by the hidden balaskite, and Panhe molybdenum deposit is skarn mineral deposit. In this area, 1∶50,000 dispersion train anomalies superimposed circular structure and tectonic development area have great prospecting potential. |
