Myanmar is endowed with a diverse array of metallic and nonmetallic mineral deposits, a number of which have recently been developed as world-class mines. Tagaung Taung deposit north of Mandalay is a resource approximately 40 km from Mandalay City. The Phayaung Taung gold deposit from the Slate Belt is hosted in phyllite, schist, and quartzite. Mineralization is associated with the stockwork quartz vein system. Wall-rock silicic alteration by cryptocrystalline quartz or amorphous silica is dominant. Phyllic alteration is characterized by sericite, quartz, chlorite, and pyrite with disseminated hematite. Gold occurs in tourmaline-quartz and sulfide-bearing quartz veins. It is associated with pyrite and chalcopyrite as well as Au-Ag-Bi-Te ore assemblages of petzite, hessite, and tellurobismuth. The Phayaung Taung gold deposit shows typical mesothermal characteristics. Scanning electron microscopy with energy-dispersive X-ray analyses revealed the average gold content of electrum grains, i.e., 75.1 wt% Au, with grain sizes ranging from 3 to 40 µm. Moreover, secondary native gold grains were formed with hematite and iron oxides in secondary remobilized/deformed veins at strongly brecciated/oxidized zones. The association between gold and altered sulfides suggests that gold was refractory in sulfides. It can be considered that supergene oxidation extended to deep mineralization veins. Such gold grains had the highest Au content, and are often in almost pure condition. This study discussed the geology, geochemistry, and mineralogy of the Phayaung Taung gold mine in Myanmar. New minerals were identified in the samples obtained from the study area, which were subjected to multiple analyses to determine their properties and understand the relationships between them.

缅甸拥有各种各样的金属和非金属矿床，其中一些最近已开发为世界一流的矿山。位于曼德勒北部的Tagaung Taung矿床距离曼德勒市约40公里。板岩带的Phayaung Taung金矿床包含闪石，片岩和石英岩。矿化与储层石英脉系统有关。隐晶石英或无定形二氧化硅对围岩硅质的影响占主导地位。绢云母蚀变的特征是绢云母，石英，绿泥石和黄铁矿以及散布的赤铁矿。金存在于电气石石英和含硫化物的石英脉中。它与黄铁矿，黄铜矿以及假石，黑铁矿和碲铋矿的Au-Ag-Bi-Te矿石组合有关。Phayaung Taung金矿床表现出典型的中温特征。扫描电子显微镜和能量色散X射线分析显示，电子晶粒的平均金含量为75.1 wt％Au，晶粒尺寸为3至40 µm。此外，次生天然金晶粒由赤铁矿和氧化铁在强烈的角砾化/氧化区的次生移动/变形脉中形成。金和改变的硫化物之间的联系表明金在硫化物中是难熔的。可以认为，超基因氧化作用已扩展到深部矿化脉。这样的金晶粒具有最高的Au含量，并且通常处于几乎纯净的状态。这项研究讨论了缅甸Phayaung Taung金矿的地质，地球化学和矿物学。
