| 摘 要： | 徐古锰矿属扬子地台西缘之松潘-甘孜地槽南缘拗陷盆地边缘沉积，分为红岩、卡门和徐古三个矿段，徐古矿段位于矿区的东部。该矿段有高精度磁异常6处，目前已发现1个锰矿层，2个矿化层，均赋存于下三叠统菠茨沟组地层中。在区域地质成矿背景和矿床特征研究基础上，对矿床成因进行了分析，认为该矿属沉积变质型锰矿床，成矿过程大致经历了铁锰的第一次富集、第二次富集等阶段，并提出了五种找矿标志。

| Abstract: | The Xugu Mn deposit lies in the margin of a depression basin on the southern margin of the Songpan-Garze geosyncline. The ore district may be divided into Hongyan, Kamen and Xugu ore blocks. 6 magnetic anomalies, 2 mineralized horizons and 1 Mn ore bed have been found in the Xugu ore block. The study indicates that the Xugu Mn deposit should be a sedimentary-metamorphic deposit. 5 prospecting criteria are put forward. |
