Mineralogy and Geochemistry of a Stratabound Manganese Deposit in the Tangganshan Region of South China

The Tangganshan manganese ore deposit is a typical sedimentary-magmatic hydatopneumatogenic superimposed ore deposit.In this paper this deposit is discussed in more detail from the following aspects: geology,ore mineralogy,and geochemistry.On the basis of its occurrence,mineral assemblage,element geochemistry,isotopic geochemistry,and characteristics of organic matter and fluid inclusions,the Tangganshan manganese ore deposit has proved to be a new-type manganese ore deposit that has been enriched by magmatie-pneumatolic solutions.Most of the ore-forming elements were derived from the ore deposit itself,and the rest from the magmatic-pneumatolitic solutions.
