摘要
F5断裂带是小秦岭金矿田北矿带主要控矿构造 ,控制了大湖、竹峪等大中型石英脉型金矿床。断裂多期次构造演化对金矿多阶段成矿起着控制作用。工业矿体主要产于有Ⅱ、Ⅲ阶段矿化叠加发育的Ⅰ阶段石英脉产出部位及其附近的蚀变岩中。断裂带产状空间形态变化控制工业矿体的空间展布规律。矿体之间距离约 1.5km ,矿化浓集中心之间的距离约 4 0 0m。预测磨石峪、闾家峪等地区是进一步找矿的有利地段。
Fracture belt F 5 is the main ore-controlling structure of the north mineralized belt in Minor Qinling Mountain gold field,controlling the large and medium sized quartz vein gold deposits such as Dahu,Zhuyu gold deposits.The multiphasic tectonic evolution of fracture played the role of controlling multistaged gold mineralization.The industrial orebody occurred in the position where the 1st staged quartz vein occurred and in its nearby altered rocks which were developed superimposedly at the 2nd,3rd stages of mineralization.The spatial morphological variation of the occurring state of fracture controlled the spatial distribution of industrial orebody.The distance between orebodies is 1.5km while the distance between densely mineralized centres is 400m.According to prognosis,the favorable districts for further ore-prospecting are Moshiyu,Lujiayu et al.
