| Geochemical Characteristics and Prospecting Prediction of Stream Sediments in Shaowu Area, Northern Fujian Province |
| Shaowu area is located in the W-Sn-Mo-Au-Ag-Pb-Zn-Nb-Ta-(pyrolytic)-fluorite metallogenic belt (Ⅲ-81) of the Central Zhejiang–Wuyishan (uplift), and in the southwest of the fluorite metallogenic sub-belt (Ⅳ-1) of the northwest Fujian, which has good prospecting prospects. In this study, the geochemical characteristics of elements, R clustering correlation, anomaly characteristics of single element, etc., show that F, Au, Pb, Zn, Nb, Ta and other elements have a certain prospecting potential, and there are 652 anomalies of order elements and 26 comprehensive anomalies. On the basis of the anomalies of stream sediments, screening and evaluation sequence and main anomaly interpretation results, combined with background of the metallogenic geologic structures, 4 areas were delineated, including Cunwei–Xialu lead-zinc mine, Wujiatang–Nanshanxia fluorite ore, Zhuling–Yanbantian fluorite ore and lead-zinc mine, and Banling–Zhangcuo fluorite ore prospecting prediction, for the prospecting direction and the next step prospecting work providing important references; The prospecting prediction area of Banling–Zhangcuo fluorite deposit were optimized, and the anomaly were verified by means of geological survey and trough exploration, and better prospecting results were obtained. |
