Abstract

• The Shwegyaung-Mankat area is situated within Banmauk Township, Katha District, Sagaing Region. It is involved Wuntho Massif Uplift bordered on the west by Chindwin Basin and on the east by Sagaing Fault. The geology of this area is predominantly occupied by Hpyu Taung Metamorphics, Shwedaung Formation, Mawgyi Andesite, Mawlin Formation, Kanza Chaung Batholith Group, and Wabo Formation. Gold mineralization associated with volcanoclastic rocks of Lower Cretaceous, mineralized quartz veins in fracture zone of Hpyu Taung Metamorphics, and intrusive rocks of Kanza Chaung Batholith Group. Gold-bearing quartz veins from the research area are characterized by sheeted veins, massive, veinlets and fracture-filling textures. Base on geological setting, structure control, alteration minerals, hosted rock and mineralization style, the research area is expected to be epithermal related low-sulfidation gold mineralization. Mineralized quartz veins hosted in Mesozoic age of volcanic, metamorphic, and intrusive rocks. Evidence of mineralized veins structure and ore texture, the mineralization style of research area is considered to be low-sulfidation epithermal deposit. The age of mineralization is probably post Paleozoic time.
