| 中文摘要: |
| 柬埔寨马德望省Phnom Prek 金矿区地质工作程度很低，基础地质资料薄弱，区内农田植被覆盖很大，表生氧化矿民采多年，地下原生矿信息较少。为了快速获取已知几处矿点的激发极化特征并在外围开展成矿预测，本研究在几处金矿点及其外围开展激电中梯测量，圈定三处与地表矿(化)关系密切的ηs异常。针对重点异常布设激电测深剖面并采用RES2DINV软件进行二维反演，对测深剖面进行地质解译推断，对矿(化)体在中深部赋存状态进行预测。经硐探工程验证揭示，中深部矿(化)体产态变化较为复杂，与反演结果吻合，取得良好的应用效果，为区内成矿预测奠定良好的基础。 |
| 英文摘要: |
| The geology of the Phnom Prek gold mining area in Battambang Province, Cambodia is very low, Lack of basic geological data, the area is covered by farmland and vegetation, Surface oxidized ore has been mined for many years by the people, the information on underground primary mine is a bit less. In order to quickly obtain the polarization characteristics of several known mining sites and carry out mineralization predictions in the periphery, the IP intermediate gradient survey was carried out at several gold mine sites and their periphery, and three ηs abnormal with surface mineralization were delineated. The IP sounding profile is set up for key anomalies and the RES2DINV software is used for 2-D inversion. Carry out geological interpretation of sounding profiles and prediction of the characteristics of deep ore bodies. Revealed by the cave project, the changes in the distribution characteristics of the middle and deep mines are more complicated. But, it consistent with the inversion results, IP sounding has yielded better application in the exploration of the gold ming area. |
