摘要
在确定地球物理工作的目的任务前提下,明确了内蒙古自治区东乌珠穆沁旗某隐伏金属矿地区的地球物理特征,结合生产实际采用大功率激发极化法、地面高精度磁法、瞬变电磁法来进行深部隐伏金属矿体勘查,在工区内寻找确定与成矿有关的物探异常;拟通过多参数的分析来降低物探解译过程中的多解性而达到提高解释精度的目的,从而为深部隐伏矿床(体)的定位预测提供较为可靠的地球物理依据。确定了异常的性质以后,进一步确定异常的规模、形态、走向变化及连续性,为进一步的地质勘查及探矿工程的布设提供物探的定性解释依据。
On the basis of determining the purpose of geophysical work,this paper defines the geophysical characteristics of a concealed ore area in Dongwuzhumuqin of Inner Mongolia Autonomous Region.Then combined with the actual production,the high-power induced polarization method,the ground high-precision magnetic method and the transient electromagnetic method are adopted to explore the deep concealed metal ore body so as to locate the geophysical anomalies related to mineralization in the working area.Through multi-parameter analysis to reduce multi-solution in the process of geophysical interpretation,the aim of improving the interpretation accuracy is attained,which provides a reliable geophysical basis for locating and predicting the deep concealed deposits.After determining its anomaly,it further determines the scale,form,trend and continuity of the anomaly,which provides the basis for qualitative interpretation basis for geological exploration and exploration engineering layout.
