| 中文摘要:本文在江西省地质勘查基金项目十余年找矿成果的基础上, 进一步阐述了江西钨锡成矿区(带)时空演化规律, 建立了江南和南岭2条钨锡多金属成矿带, 进而划分9条成矿亚带和15个矿集区; 厘定了包括江南地块与燕山期Ⅰ型中酸-弱酸性斑岩有关的铜钨金钼矿床成矿系列等共3个成矿系列、与燕山晚期S1型酸性花岗岩有关的钨锡钼银矿床成矿亚系列等6个成矿亚系列和朱溪式等15个矿床式; 总结了3个钨锡多金属矿床成矿系列特征及成矿规律, 剖析了朱溪、大湖塘、东坪、松树岗等找矿重大突破典型案例; 提出了“异常指方向、标志定靶区、主攻新类型”的“面上选点”找矿预测及勘查思路, 研发了“脉面层体”就矿找矿法的“点上突破”朱溪式“关键控矿要素识别勘查模型+地球化学元素示踪+地球物理三维反演+钻探”等快速、精准、高效探测技术组合的找矿方法, 对江西钨锡矿找矿潜力进行评价分析, 并提出下一步找矿建议。 |

| Tungsten-tin Polymetallic Metallogenic Series and Prospecting in Jiangxi Province |

| Abstract: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. |
