| 中文摘要: |
| 位于南岭成矿带中段北缘的黄沙坪铅锌多金属矿田，是湖南省最大的铅锌矿产地，其开采历史悠久，基础地质研究程度较高。目前矿区面临资源枯竭与接续问题，亟需开展地球物理深部探测，预测及寻找深部隐伏矿体。本文采用广域电磁法探测研究区深部地质构造和隐伏岩体的形态及规模，拓展深部找矿空间。探测结果表明：广域电磁法在本区能较好的识别深部地质信息，矿区深部还存在大范围岩体，在岩体与围岩接触带仍具有较大找矿潜力。 |
| 英文摘要: |
| The Huangshaping lead-zinc polymetallic ore field in the north margin of the central part of Nanling metallogenic belt is the largest lead-zinc ore producing area in Hunan Province， with a long mining history and a high degree of basic geological research. At present， the mining area is faced with the problem of resource depletion and continuity. The deep geophysical exploration has certain guiding significance for forecasting and searching deep hidden ore bodies. This time， through the wide field electromagnetic exploration in Huangshaping ore field， the deep geological structure and the form and scale of buried rock mass are detected， and the deep prospecting space is expanded. The results show that the wide field electromagnetic method can identify the deep geological information in this ore field， and there is still a wide range of rock mass in the deep， and there is still a large prospecting potential in the contact zone between rock mass and surrounding rock. |
