Abstract:

The Muli antimony ore bodies in Yunnan have close relationship with the faults. To solve the deep and edge prospecting problem of the deposit, the FD-3017 RaA radon measuring instrument was used to detect the buried faults in No.3 anticline of Muli antimony ore bodies. The data indicate that all of the known faults (including faults of Xiaopunong, F1, F2 and F3) and ore bodies show clear radon anomaly. It is suggested that the radon measurement may be an effective method to search for buried faults and an auxiliary method to search for buried deposits which have close relationship with the fracture structure including faults, joints and cleavages. The results reveal that there are two large buried faults in the core of the anticline and the northeastern study area, respectively, and there are many secondary faults of the known faults and the predicted faults. In the end, the radon anomaly model of the study area is summarized
