| 开展深部找矿预测，地球物理方法发挥着重要作用，但是受多解性困扰. 本文以湖南东北某金矿为例，探讨运用多种地球物理方法，提高深部找矿预测的准确性。开展了大比例尺重力测量、地面高精度磁法及可控源音频大地电磁测深法观测，圈定了深部找矿靶区，经钻孔及地球物理电、磁测井验证，效果突出，确定了本区的地球物理找矿标志。表明应用综合物探方法在本区深部矿产远景调查评价中是快捷有效的，建议将这一地球物理勘查模式在全国的深部矿产远景调查评价中予以推广。 |

| Geophysical methods play an important role in forecast of deep prospecting. While they face the problem of multiple solutions. Taking a gold deposit in northeastern Hunan as an example, this paper address the issue how to improve the accuracy of prediction of deep prospects using integrated multiple geophysical techniques. In this area, a comprehensive survey has been conducted including large-scale measurements of gravity, precise magnetism and CSAMT(controlled source audio magnetotellurics) to delineate the deep prospecting targets. The geophysical marks of this area were determined through drilling validation and geophysical electric, magnetic logging, indicating outstanding results of the geophysical survey. It demonstrates that the application of integrated geophysical methods to evaluation of deep mineral prospects is fast and effective. It is recommended that such a geophysical exploration model can be spread all over the country. |
