三维时间域激发极化法探测花牛山铅锌矿的试验研究
|
摘要
采用中国自主研制的"大深度三维电磁探测系统"在甘肃柳园花牛山铅锌矿开展的三维时间域激发极化法探测试验研究成果。对比了单一方向供电与多方向供电探测结果,并对成果进行了地质解译。研究显示:垂直主构造供电三维数据反演结果较为可信,多方向供电数据联合反演有利于提高探测结果的可靠性;利用三维时间域激发极化法探测结果建立三维电性结构模型,对解构地下三维地质结构效果明显;异常与地球物理扫面测量成果及地质资料吻合。根据试验结果弄清了矿体的容矿层位、矿体与地层的关系,可为深部地质结构推断与矿产资源评价提供依据。
A three-dimensional time-domain induced polarization exploration experimental result of lead-zinc mine in Gansu Liuyuan Huaniushan was described using the "high depth of the 3D electromagnetic exploration system"independently developed by China. It compared test results of single transmit direction with multi-directional transmit method and made the geological interpretation. Results show that inversion results of the 3D data of with the power supply perpendicular to the main structure are credible,and the joint inversion of the multi-directional power supply data is helpful to improve the reliability of the results. The three-dimensional electrical structure model is established by using the 3D time-domain induced polarization method. The effect of deconstructing 3D subsurface geological structure is obvious; anomalies in good correspondence with geophysical contour map data and geological data. By using the results of the 3D electrical exploration,the spatial distribution of the ore-bearing stratum,as well as the relationship between the ore bodies and the stratum,were revealed. The results potentially provided evidence for future interpretations of deep geological structures,along with evaluations of mineral resources.
