| Tungsten-tin Polymetallic Metallogenic Series and Prospecting in Jiangxi Province |
| Based on the ten-year achievements of the Jiangxi Province Geological Exploration Fund Project, we elaborated the spatiotemporal evolution regulation of the metallogenic area (belt) of tungsten-tin deposits in Jiangxi. Furthermore, two tungsten-tin polymetallic metallogenic belts were established in Jiangnan and Nanling, as well as nine metallogenic sub-belts and fifteen ore concentration areas. Three metallogenic series of copper, tungsten, gold, and molybdenum deposits associated with Yanshanian medium-acid and weak acid type I porphyries in the Jiangnan block, six metallogenic sub-series such as the tungsten-tin-molybdenum-silver deposits related to Late Yanshanian S1 type acid granite, and fifteen ore deposit types such as Zhuxi type were determined. We summarized the metallogenic series characteristic and metallogenic regularity of three tungsten-tin polymetallic deposits in Jiangxi Province. The Zhuxi, Dahutang, Dongping, and Songshugang deposits were examined as examples of major prospecting breakthroughs. We proposed a prospecting, forecasting, and exploration concept called “selecting points on the surface,” in which the “anomaly” determined the target, and we focused on the new type. Moreover, we developed a “breakthrough on the point” exploration technology and method, and the technology and method follow the regulation of orebody emplacement, which was named “the intrinsic connection between vein, structure surface, stratum, and body.” Finally, after evaluating and analyzing the prospecting potential, we provided suggestions regarding further prospecting for tungsten-tin deposits in Jiangxi Province. |
