焦家断裂带南段深部地球物理地球化学特征与找矿方向
|
摘要
该文选取焦家断裂带南段的徐村院—史家地区作为研究的重点地区。通过可控源音频大地电磁测深、激电测深、钻探验证等手段,首次确定焦家断裂带自徐村院—姬家—黄家西—史家西—大尹家东一线延伸方向,将焦家断裂带沿走向向南推断了6km;认为焦家断裂带南段倾向W,倾角30°~50°,局部可达78°,断裂平面上呈S形,形态不规则;查明了焦家断裂带南段深部地球物理、地球化学特征;钻探揭露了焦家断裂带南延位置,拓展了焦家金矿带的找矿空间,提出了新的找矿方向。
In this paper,selecting Xucunyuan—Shijia area in southern Jiaojia fault belt as a key study area,by using electrical resistivity,electrical sounding,drilling verification and other means,it is firstly determined that Jiaojia fault belt extends along Xucunyuan—Jijia—Huangjiaxi—Shijiaxi—Dayinjiadong.The Jiaojia fault zone is inferred to be 6 km along the strike southward.It is regarded that the trend in southern Jiaojia fault belt is NW,and inclination angle is 30°~50°which can reach 78°in regional area.The fracture shows S shape and irregular shape in plane.Geophysical and geochemical characteristics in deep part of southern Jiaojia fault belt have been identified.Drilling reveals the southern extension position,expands prospecting space,and puts forward a new prospecting direction of Jiaojia fault belt.
