摘要
嵩县大桩沟钼矿是新近发现的产于东秦岭钼多金属成矿带东段的一个具代表性的层状钼矿床。从石英脉—蚀变岩—蚀变流纹斑岩型钼矿,显示了一个完整的层状钼矿成矿模式。笔者对区内成矿条件、矿床特征、控矿要素和成矿期次等进行了阐述,矿体产出受地层、构造、岩浆岩三位一体控制明显,成因属受地层层间裂隙控制的中、低温热液充填型层状钼矿床;总结了矿化规律与找矿标志;远景评价显示中深部钼成矿潜力依然较大,预计规模可达中型以上。
The Dazhuanggou is a newly discovered molybdenum deposit in the eastern section of the well-known East Qinling poly-metallic mineralization belt. A complete model of stratiform molybdenum mineralization is present at Dazhuanggou with assemblage of different style mineralization composed of quartz vein, altered rock and altered rhyolite porphyry. The geology, ore deposit characters, ore-controlling factors and mineralization stages are discussed, the mineralization is obviously controlled by strata, structure and magmatie rocks, and the it is a meso-epithermal hydrothermal infilling stratiform deposit mainly controlled by the interlayer fractures of strata. The paper summarized the ore-forming conditions, characteristics of ore deposits, metalloge- netic factors and mineralization laws, and concluded that there is still great ore-forming potential in deeper parts and the deposit which could be medium size at least.
