胶东栖霞地区西林断裂带深部结构特征与找矿方向
Deep Structural Characteristics and Prospecting Direction of Xilin Fault Zone in Jiaodong Area
摘要
Abstract
In recent years,through exploration work in Xilin fault zone,it is found that there is a good phe-nomenon of gold mineralization in the deep part.This fault zone is expected to become one of the impor-tant mineralization zones in Jiaodong area and lead the strategic transfer of exploration direction of gold de-posits in Jiaodong area.The deep structural characteristics of Xilin fault zone are key scientific problems that urgently need to be addressed in order to achieve breakthroughs in mineral exploration in this fault zone.Reflection seismic,controllable source audio magnetotelluric(CSAMT),wide area electromagnetic sounding,and mechanical core drilling are carried out to reveal the deep structural characteristics of Xilin fault zone.The physical characteristics of different geological bodies in the area have been identified,and the deep spatial distribution pattern of Xilin fault zone has been deduced.There are obvious high resistance and low resistance zoning phenomena at the elevation of-600m~-800m.Through drilling,it is revealed that the contact position between Xilin fault zone and the surrounding rocks is at an elevation of-610m.It has verified the inferences of the occurrence location and the control of deep extension of Xilin fault zone in this geophysical exploration work.It will provide a geophysical basis for further geological work in this area.关键词
