Abstract. Manganese (Mn) ore deposits are widely distributed in China and can be divided into six types based on origin and subsequent modifications: (1) sedimentary, (2) volcanic-sedimentary, (3) metamorphosed, (4) hydrothermally modified, (5) hydrothermal, and (6) supergene. Sedimentary and supergene Mn ore deposits are …
The Mineralogy of Iron and Manganese Ores of the Ushkatyn-III Deposit
Abstract The Ushkatyn-III in Central Kazakhstan is a weakly metamorphosed hydrothermal–sedimentary ore deposit of the Atasu type. For such objects, an assemblage of stratiform bodies of iron–manganese and polymetallic (lead–zinc and barite–lead) ores is typical. At the Ushkatyn-III deposit, there are iron, manganese, and barite–lead ores …
