摘要
广西鹰扬关—张公岭位于博白—岑溪—鹰扬关深断裂带的北东端。区内银、金矿的成矿受地层、构造、岩浆热液 (或变质热液 )活动控制。主要矿床类型有破碎带硫化物型、破碎带黄铁绢英岩型、石英脉型。地球化学异常反映了该区的成矿特点。通过对银、金矿床地质背景、矿床分布规律及银、金矿床地球化学特征的研究 。
Yingyangguan-Zhanggongling region is located in the northeast margin of Bobai-Chenxi-yingyangguan deep-rooted fracture zone. The metallogeny of silver and gold deposits in the region was controlled by stratum, structure and the activities of magmatic or metamorphic hydrothermal fluid.The main deposit type includes fracture zone sulfide deposit,fracture zone pyrite sericite quartz deposit and quartz vein deposit.The mineralizing features of the region can be showed by geochemical anomalies.Some indexes for ore prospecting in the region have been proposed by the research on geological background,distribution regularities and geochemical features of silver and gold deposit.
