摘要

胶东招平断裂几十年来黄金产量一直位居全国首位,但近十年没有大的找矿成果,其中一个重要原因是多数人认为破头青断裂为招平断裂北段的主干断裂,忽略了对九曲蒋家断裂的找矿。近年来在水旺庄矿区取得深部找矿突破,新增金资源量170余吨。通过水旺庄矿区大量深部钻孔配合地表实测剖面及区域调查研究等手段,系统揭露了控矿断裂深部形迹,揭示了九曲蒋家208断裂与招平断裂的空间关系。按照以往招平断裂尖灭于龙口市颜家沟村的认识分析,尖灭位置距水旺庄矿区直线距离仅1.9km,招平断裂北段的找矿空间已不大。明确了九曲蒋家208断裂为招平断裂北段主干后,招平断裂北段再次展现出巨大的找矿潜力。
        Being the No.1 gold producer in China for decades, however, the Jiaodong district lags behind in resource increment and awaits a prospecting breakthrough. It is generally accepted that the Potouqing Fault was the main fracture in the northern section of the Zhaoping fault zone. As a result, ore prospecting in the Jiuqujiangjia Fault has been neglected. In recent years, there has a breakthrough in deep prospecting in the Shuiwangzhuang prospecting area with newly increased gold reserve of more than 170 tons. The great number of deep drilling along with many measured sections and systematic regional geological survey revealed the features of the ore-controlling structure at depth and the spatial relationship between the Jiuqujiangjia 208 Fault and the Zhaoping Fault zone in the Shuiwangzhuang prospecting area. The Zhaoping Fault was believed to be pinch-out in Yanjiagou village, Longkou City. Therefore, many researchers believed that there is hardly any space for prospecting in the northern section of the Zhaoping Fault zone, as distance between the Shuiwangzhuang prospecting area and the fault pinch-out site is only 1.9 km. The recognition of the Jiuqujiangjia 208 Fault as the main ore-bearing fracture in the northern section of the Zhaoping fault zone shows that this area has huge prospecting potential.
