Geochemical Features of Danzhai Carlin-Type Gold Deposit,Southeast of Guizhou

  The petrochemistry and trace element data show that the change law of SiO2, Au, As, Sb, CaO, CO2 and MgO contents from unaltered to the most intensely silicified limestones.The REE contents and partition patterns of the altered and mineralized rocks are largely consistent with those of the unaltered host rocks (laminated limestone).The REE content of intensely carbonated rocks is lower, MREE is slightly enriched.The fluid inclusion data indicate that the ore-forming fluids are of the Cl-rich type and that exploding temperatures of fluid inclusions in the quartz and calcite are about 200~338℃.The geochemical study of isotopes such as S, O, H and Pb shows that the medium-water of ore fluids is dominantly of meteoric origin.The ore-forming materials are predominately of crust source with small amounts of mantle component.
