Helium and Argon Isotope Compositions of Fluid Inclusions in Pyrite from Shizhuyuan W-Sn-Mo-Bi Deposit, Hunan Province
The Shizhuyuan deposit, a world-daw W-Sn-Mo-Bi polymetallic deposit, is called the nonferrous metal museum in the world. Many scholars presented their research results in various aspects. However, the origin of ore-forming fluids has long been a focus of discussion. The 3He/4He ratios of fluid inclusions in pyrite from this deposit range from 0.06Ra to 1.66Ra, and the 40Ar/36Ar ratios from 316 to 1 085, indicating that the ore-forming fluid to a mixture of at least two end-member components, mantle-derived fluid and air-saturated crustal fluid. The Qianlishan granite belongs to A-type granite with high K, low Na, high 143Nd/144Nd, low TDM, 87Sr/86 Sr and δ18O, and low Rb/Sr, suggesting that the Qianlishan granite is related to mantle-source material The Shizhuyuan deposit to located at the contact zone of the Qianlishan granite, and its mineralization time to consistent with the intrusion of Qianlishan granite. This Indicates that the mantle-derived fluid is from the A-type granitic magma.
