| 中文摘要: |
| 寻找隐伏金属矿产是我国矿产勘查的主要任务之一。近几年,中国地质科学院地球物理地球化学勘查研究所在内蒙古锡盟地区做了大量的电法勘查工作,主要应用大功率激电和可控源音频大地电磁测深方法组合进行隐伏矿探测研究。大功率激电用于矿区及其外围的面积测量工作,快速发现和圈定矿化构造展布情况；采用可控源音频大地电磁测深方法,利用其反演电阻率断面电性分布特征,推断地下地质结构、构造产状和矿(化)体的赋存空间。为钻探工程提供依据,取得了很好的找矿效果。 |
| 英文摘要: |
| Exploring the concealed metallic ore deposit is one of main exploration tasks, a large amounts of electrical prospecting has been carried out by Langfang Institute of Geophysical and Geochemical Exploration in the Ximeng region, Inner Mongolia in recent years. Main electrical prospecting methods include high power IP and the controlled source audio-frequency magnetotelluric sounding method to explore the concealed metallic ore deposits. The high power IP survey is conducted in the mining area and its surrounding area, so as to detect and delineate the ore-controlling structures and their spatial distribution. The controlled source audio-frequency magnetotelluric sounding method is used to infer the underground geological structures, structural attitude and spatial location of hidden orebodies by using the principle of the interpreted electrical distribution on section based on inversion modelling. The geophysical survey provided the reliable basis for test drilling, and the promising exploration result has been achieved. |
