文摘

The Mari deposit is strata-bound that hosted by the Eocene andesite rocks. Sulfur isotope compositions have a negative range from δ34S = − 2.7 to − 3.4‰, suggesting the presence of a reducing environment resulting from activation of sulfate reducing bacteria. The geology, ore mineralogy, alteration characteristics and sulfur isotopic compositions suggest the Mari deposit is similar with Chilean Manto-type deposit.
