| 中文摘要: |
| 达秧乡金、锑矿(化)点位于滇黔桂“金三角”的重要区域-册亨县，容矿地层为中三叠统边阳组第一段(T2b1)和许满组第四段b亚段(T2xm4b)，赋矿岩性主要为细砂岩、粉砂岩、泥岩，区内蚀变点、矿(化)点分布广泛，其中金地表最高品位达051×10-6，且锑矿与化探异常套合较好。区内断层构造、褶皱构造发育，其中区域断层-板昌断层作为导矿构造，其旁侧次级断层为容矿构造。笔者认为该区具有较好的成矿地质条件，有望发现深部金、锑矿盲矿体，实现区域金、锑找矿突破。 |
| 英文摘要: |
| The Dayang gold-antimony occurrence is located in Ceheng where is the critical region of the “golden triangle” in Yunnan-Guizhou-Guangxi. Host stratas are the first Member of Middle Triassic Bianyang Formation(T2b1) and the fourth-b Sub-member of Middle Triassic Xuman Formation(T2xm4b).The host rocks are mainly composed of grained sandstone,siltstone, mudstone. The alteration points and ore occurrences are widely distributed in the Dayang area. The highest taste of gold is 0.51×10-6 among those alteration points and ore occurrences,and antimony is well matched with geochemical anomaly. Faults and folds are well developed in the area. The regional fault-Banchang fault is used as the guide structure and its lateral secondary faults are ore-bearing structure. The authors believe that there are better metallogenic geological conditions in the region so that it is expected to find the deep gold-antimony mine blind ore body and achieve regional gold and antimony prospecting breakthrough. |
