| 摘 要： | 本文基于辽宁第九地质大队2015—2017年间在桂西北尾腊沟金矿勘查过程中的新发现而撰写。桂西北尾腊沟金矿体主要赋存于中三叠统兰木组二段第3亚段的压碎泥岩、粉砂岩、细砂岩中;而铂族元素矿则是在兰木组二段第1、2、3亚段地层中,均存在不同程度的铂(族)矿化。区内的铂族元素不单纯局限在金矿体内,在其围岩中也同样存在,找矿潜力乐观。本次在桂西北中三叠统砂岩、泥岩中发现高品位的铂族元素,突破了我国在川黔滇围绕寒武系黑色页岩中寻找铂族元素矿的束缚,无疑对今后铂族元素的找矿方向拓宽了新的思路,也为研究铂族元素的成矿机制提供了新的线索。

| Abstract: | This paper introduces new discovery of prospecting in Weilagou gold deposit in northwest Guangxi province conducted by the 9th geological team during 2015-2017. Ore bodies of the gold deposit occur mainly in Middle Triassic Mulan Formation. Various PGE mineralization is discovered in the 1st, 2nd 3rd sub-member of the second Member of Mulan Formation. PGE in the area occur not only in the gold ore bodies but also in the surrounding rocks and is potential for further prospecting. During this prospecting high grade PGE is discovered in Middle Triassic sandstone and mudstone breaks through the tie of prospecting PGE around Cambrian black shale in Sichuan,Yunnan and Guizhou provinces and widen thought of PGE prospecting and supplies a new clue for metallogenic mechanism of PGE. |
