综合物探方法在安徽定远小庙山金矿勘查中的应用

Application of multiple geophysical techniques to the gold deposit exploration in the Xiaomiaoshan area

张八岭构造带是我国重要的金矿成矿带。本文根据综合物探方法,在安徽定远小庙山勘查区张八岭群西冷岩组的构造带中寻找含金银煌斑岩脉,通过对地面实测的磁异常数据处理,解译有利于识别的磁异常,进行重磁剖面、激电中梯及大功率激电测深测量,提取有利于找矿靶区的综合物探异常。该研究方法为小庙山勘查区深部找矿、外围找矿工作及找矿靶区的初选提供了参考。

The Zhangbaling tectonic belt is an important gold mineralization belt in China. Multiple geophysical techniques were applied to exploration of gold-and silver-bearing lamprophyre dikes in the structural belt of the Xileng Formation-Complex of the Zhangbaling Group in the Xiaomiaoshan exploration area, Dingyuan, Anhui. The magnetic data measured on the ground was processed and interpreted to help identify the magnetic anomaly. The gravity and magnetic profile, IP intermediate gradient and high-power IP sounding were carried out to extract the integrated geophysical anomaly for locating the prospecting targets. This research method provides a reference for prospecting in the deep and periphery of the Xiaomiaoshan exploration area, and also for initial determination of prospecting targets.
