摘 要: | 简要介绍了加拿大航空物探发展的现况,并以新斯科舍省悉尼铜钼多金属矿为例,介绍了大比例尺航空物探在勘查中的应用及取得的成果。通过收集矿区区域航磁以及部份地段的地面高磁,以资料的处理、融合、分析为手段,以地质为依据,利用已经掌握的地质规律,建立测区内可能有的几种地质模型及地球物理模型,划分出矿区区域地质构造、岩体,并圈定了有价值成矿的靶区,为地质勘查和找矿提供了帮助。

Abstract: | This paper briefly introduces the development status of the Canadian airborne geophysical survey by taking Nova Scotia province Sydney Cu-Mo Polymetallic mine as an example,and introduces the large scale aerial geophysical prospecting and its achievements.Through the collection of mining area aeromagnetic and the partial ground magnetic surveying data,and with data processing,integration and analysis based on the geology and the already available geological rule,several geological models and geophysical models have been established in the survey area,which have been used to the division of mining area geological structure,classification of rock mass and the delineation of valuable ore target areas for prospecting,and offering the help for geological exploration. |
