摘要
河北省沽源县张麻井铀钼矿是上世纪八十年代发现的大型火山热液型铀钼矿床,近几年,该区外围铀钼多金属矿找矿工作十分活跃。笔者通过对区域地质背景及张麻井铀钼矿地质特征分析,阐述了张麻井铀钼矿控矿因素。概况外围多个矿点,特别是秦家营地区成矿地质条件与该矿具相似性,找矿前景看好。笔者认为在秦家营地区应重点研究断裂-次火山岩-矿体三者之间的关系,注意次火山岩体和火山机构对成矿的控制作用,并对沿北东向F45断裂圈定的Ⅰ、Ⅱ号远景区重点开展找矿工作。
The Zhangrnajing large volcanic-thermal type uranium and molybdemum deposit was discovered in Guyuan County,Hebei Province, in the 80s of the 20th century. In recent several years, the peripheral prospecting work develops very well around this deposit. This article intruduces the control factors of Zhangrnajing U-Mo deposit. We found that the metallogenetic geological Conditios of some ore spots are similar with Zhangmajing deposit, espectilly the Qinjanen ore spot. Based on the control factors of Zhangmajing U-Mo deposit, The authors suggest that the relationship among the faults,subcolcanic rocks and deposit should be studied seriously, and the ore-forming control factors of the volcanic rocks and volcanic apparatus should be paid more attention to, and the outlied I and Ⅱ prespecting areas along NE diarection fault should be started prespection.
