摘要
谢家沟金矿位于焦家—新城断裂和招远—平度断裂之间,区内出露的岩浆岩主要为中生代的片麻状黑云母玲珑花岗岩以及酸性、中性和基性脉岩。本区的金矿床主要受到构造、脉岩两种因素的影响。其中构造是最主要的控矿因素,它不仅影响蚀变岩的分布,也影响着脉岩和矿体的产出分布;脉岩对矿体的产出也有一定的影响。矿脉一般赋存于NE、NNE向的断裂中,在脉岩与断裂的交汇部位矿体矿体明显变富。
The XieJiaGou gold ore is located between the ZhaoPing fault zone and JiaoJia - XinCheng fault zone. The granites consist of Linglong gneissic biotite granite mainly, next to it all kinds of rock veins. The major gold deposit of this ore is controlled by the structures and rock veins, which control 90% ore veins. The structure is the major control complication, which control 90% ore veins. The rock veins is also a ore control complication in this gold deposit. Ore veins usually occur in the faults of NNE and NNW trend. The ore bodies are rich in the place wherethe dip of faults become gentle from steep or in the turning point.
