In-situ pyrite trace element and sulfur isotope characteristics and metallogenic implications of the Qixiashan Pb-Zn-Ag polymetallic deposit, Eastern China

Ore Geology Reviews (2022)

Wendong Zhang Bin Li Anhuai Lu Kui-Dong Zhao Safiyanu Muhammad Elatikpo

The Qixiashan Pb-Zn-Ag deposit (2.6 Mt at 13.4% Pb + Zn and 3.9 Kt at 236.5 g/t Ag) in the Middle-Lower Yangtze River Valley Metallogenic Belt (MLYRB) is the largest Pb-Zn-Ag polymetallic deposit in Eastern China. The stratabound orebodies are hosted in the Carboniferous carbonate units. Whether this deposit and other sediment-hosted deposits in MLYRB are associated with Late Mesozoic magmatism or Carboniferous sedimentary exhalative events is still disputed, due to the poor constraints on their ore-material source and metallogenic processes. In-situ pre-/syn-ore pyrite S-isotopic and trace-element data from Qixiashan favor a seawater sulfate origin over a magmatic-hydrothermal one. Framboidal pyrite (Py1) is likely diagenetic, as evidenced by its low Co/Ni ratio (<1), size (∼4 μm), and negative δ34S values (−27.4 to −2.2‰) caused by bacterial sulfate reduction (BSR). Pre-ore colloform (Py2) and massive (Py3) pyrites have high Mn concentrations, whereas syn-ore pyrites (Py4 and Py5) have elevated Pb, Zn and Cu grades. The low Co/Ni values of the pre-/syn-ore pyrites indicate that both the Fe and base metals are of non-magmatic diagenetic origin. Sulfur isotope fractionation in the fluid may have reached equilibrium in the Pb-Zn-Ag metallogenic stage. Equilibrium fractionation calculation suggests that the positive shift of δ34S values from Py2 to Py5 (10.2 to + 22.2‰) is primarily caused by thermochemical sulphate reduction (TSR). Pre-ore pyrites were likely formed in early carboniferous diagenesis, and then enclosed by epigenetic pyrites. Iron in the syn-ore pyrites was most likely recycled from sediments or pre-ore pyrites via dissolution-leaching or replacement processes. During the Qixiashan Pb-Zn-Ag mineralization, the magmatic-hydrothermal fluid is unlikely a major base metal source.

Rare Earth Element and Trace Element Features of Gold‐bearing Pyrite in the Jinshan Gold Deposit, Jiangxi Province

Acta Geologica Sinica - English Edition (2010)

Guangzhou Mao Renmin Hua Jianfeng Gao Kui-Dong Zhao Long Guangming

Abstract: Jinshan gold deposit is located in northeastern Jiangxi, South China, which is related to the ductile shear zone. It has a gold reserve of more than 200 tons, with 80% of gold occurring in pyrite. The σREE of gold‐bearing pyrite is as higher as 171.664 ppm on average, with relatively higher light rare earth elements (LREE; 159.556 ppm) and lower HREE (12.108 ppm). The σLREE/σHREE ratio is 12.612 and (La/Yb) N is 11.765. These indicate that pyrite is rich in LREE. The (La/Sm) N ratio is 3.758 and that of (Gd/Yb) N is 1.695. These are obvious LREE fractionations. The rare earth element (REE) distribution patterns show obvious Eu anomaly with average δEu values of 0.664, and δCe anomalies of 1.044. REE characteristics are similar to those of wall rocks (regional metamorphic rocks), but different from those of the Dexing granodiorite porphyry and Damaoshan biotite granite. These features indicate that the ore‐forming materials in the Jinshan gold deposit derived from the wall rocks, and the ore‐forming fluids derived from metamorphic water. The Co/Ni ratio (average value 0.38) of pyrite suggests that the Jinshan gold deposit formed under a medium–low temperature. It is inferred from the values of high‐field strength elements, LREE, Hf/Sm, Nb/La, and Th/La of the pyrite that the ore‐forming fluids of the Jinshan gold deposit derived from metamorphic water with Cl>F.
