中文摘要:
      首先通过对查嘎尔崩金矿工作区内实测数据,进行各项改正及数据处理(化极、延拓),绘制出简单清晰磁异常图,然后结合岩石地球物理特征、实际地质填图成果综合分析解译,大致划分出第四系覆盖下各岩性大致分布情况,推断出断层构造位置及走向。最后将它们的赋存特征与区域控矿构造对比,大致判断各推断构造赋矿性,从而划出找矿靶区。后期激电、槽探、钻探等工作证明,该靶区圈定较为准确合理。
英文摘要:
      First correction and data procession (reduction to the pole, continuation) are made according to the measured data in Chagaerbeng gold deposit and simple and clear magnetic anomalies are map out. Then combined with rock geophysical characteristics and the comprehensive analysis of interpretation of the field geological mapping result lithologic distribution under the Quaternary cover is roughly lineated, locations and strike of faults inferred. Finally the occurrence characteristics of them are compared with regional ore-controlling structures, their ore-hosting property approximately is inferred and the gold prospecting targets located. IP survey, trenching、drilling work prove that the target lineation is correct, accurary and reasonable.
