| 英文摘要 | The Kangshan Au-polymetallic deposit, in the Xiong'ershan District of China, lies on the southern margin of the North China Craton. The orebodies are hosted in (E)NE-(W)SW-trending brittle faults formed during the Mesozoic, which crosscut Neoarchean metamorphic rocks and Mesoproterozoic volcanic rocks. The ore-forming process can be divided into three stages: a quartz +/- pyrite stage (Stage 1), a quartz-polymetallic sulfide stage (Stage 2), and a quartz-calcite stage (Stage 3). Stage 2 includes two substages: a quartz-pyrite-chalcopyrite-electrum substage (Stage 2-1; the main Au mineralization stage) and a galena-sphalerite-pyrite-ankerite-Ag-bearing tetrahedrite +/- chalcopyrite +/- electrum substage (Stage 2-2; the main Pb-Zn-Ag mineralization stage). Four types of fluid inclusions have been identified in the Kangshan deposit: three-phase CO2-rich inclusions, two-phase aqueous inclusions, one-phase vapor inclusions and one-phase aqueous inclusions. Inclusion micro-thermometric, laser Raman, and C-H-O-S-Pb isotope analyses were undertaken to clarify the properties of the ore-forming fluids, sources of these fluids and ore-forming materials, and mineral precipitation mechanisms. Laser Raman spectroscopic analysis indicate that the ore-forming fluids were formed in a NaCl-H2O-CO2 system. Inclusion homogenization temperatures and salinities are 130 degrees C-359 degrees C, and 0.53-11.46 wt% NaCl equivalent (eqv.), respectively. delta O-18(fluid) values calculated from the delta O-18(SMOW) and delta D values of the inclusions in auriferous quartz veins are 1.0-9.0 parts per thousand and -92 parts per thousand to -67 parts per thousand, respectively. delta C-13(PDB) and delta O-18(SMOW) values of ankerite are -4.89 parts per thousand to -3.67 parts per thousand and 12.0 parts per thousand-13.9 parts per thousand, respectively. Fluid C-H-O isotopic compositions indicate that the ore-forming fluids originated mainly from magmas, with minor addition of meteoric water. delta S-34 values of the ore sulfides are 4.8 parts per thousand-7.4 parts per thousand; Pb-206/Pb-204, Pb-207/Pb-204, and Pb-208/Pb-204 ratios of the ore sulfides are 17.625-17.889, 15.543-15.620, and 38.389-38.740, respectively. S-Pb isotopic compositions indicate that the ore-forming materials of the deposit originated from granitic magmas and host rocks. The Kangshan Au-polymetallic deposit is a medium-low-temperature hydrothermal deposit. Its mineralization may be related to Early Cretaceous granite formed in an extensional tectonic setting caused by craton destruction on the southern margin of the North China Craton. |
