The two main components of the Mn-ore deposit are Mn-carbonates and Mn-bearing aluminosilicates.

Mn-carbonates formed by reaction of hydrothermally sourced Mn and sedimentary organic matter

Aluminosilicates derived from weathering of Neoproterozoic continental basalts on Yangtze Block

The Datangpo Mn deposit conforms to the “episodic ventilation” model of metallogenesis.
