“…(5) In the source region of the metallogenic fluid or organic matter-rich strata below the orebodies penetrated by the fluid, water-rock reactions will solvate adjacent carbonates and cause an exchange of C-O isotopes between the fluid and the strata. This ultimately causes 13 C of the fluid to increase and 13 C of the adjacent rocks to decrease. [51,52].…”

“…This particular deposit has been exhaustively studied by a number of scholars, and a series of important findings have been made in studies on the geological background of the mining areas in Northeast Yunnan [2][3][4], the geochemistry of the deposit [5][6][7][8][9][10][11][12][13][14], the tectonic setting of the ore fields [15][16][17], and the formation of the deposit [2-8, 15, 16, 18-22], thus providing a wide range of resources for this study to access and build upon. While consensus has been reached on topics such as the tectonic setting of the lead and zinc deposits in the region [11,[23][24][25][26][27] (boundaries of a stable platform), distribution characteristics [23]).…”

“…(1) Fluid mixing: based on C-O isotopic analysis, Huang et al [8,[33][34][35] believe that the mixing of crust and mantle fluids is the key to metallogenesis; Luo et al [36] proposed that mixing between fluids is the primary mechanism of precipitation, based on their summation of previous studies on fluid inclusions; Zhang et al [37][38][39][40] believe that the processes of fluid mixing and boiling are the primary causes of sulfide precipitation, based on the results of studies on strontium isotopes and fluid inclusions. (2) Fluid boiling: Han et al [12,13,23] performed a detailed study of the geological characteristics and fluid inclusions and came to the conclusion that fluid boiling is the primary mechanism of mineral enrichment and metallogenesis. (3) pH changes: several authors believe that sulfide precipitation is mainly caused by changes in pH [7,41,42].…”

This work investigates the ultra-large Huize Pb-Zn deposit, based on the results of preceding studies and detailed field geological surveys. The existing findings were reorganized and reinterpreted and supplemented with C-H-O isotopic measurements, which resulted in the identification of two different metallogenic fluids: a high temperature, low salinity, and acidic Fluid A, which originates from deep-seated fluids and is enriched in lighter C and O isotopes (−3‰ < 13 C‰ < −4‰; 10‰ < 18 O‰ < 17‰; −92‰ < D‰ < −50‰), and a low temperature, high salinity Fluid B, which is a subsurface brine formed by atmospheric precipitation. Fluid B is characterized by heavier C-O-H isotopic compositions (−2‰ < 13 C‰ < 1‰; 2‰ < 18 O‰ < 24‰; −66‰ < D‰ < −43‰) than Fluid A and cycles continuously within the strata. We hypothesize that the Huize Pb-Zn deposit is the result of large-scale fluid migration from deep regions of the crust. These upward-moving fluids extracted metallic elements from carbonate strata of various ages, forming a metal-rich metallogenic fluid (Fluid A). After higher-grade ores were precipitated from the fluid following decompression boiling, it then mixed with Fluid B and continued to precipitate sulfides.

“…China have played a major role in the development of the non-ferrous industry of China (Han et al 2007) and generated large quantities of mine waste without any proper treatment. Such long-time, large-scale mining activities have led to the release of Cd, Pb, Zn, and As in large amounts from ores into soils and other supergene environment and may pose a great health risk to the people who live in the surroundings.…”

China is one of the largest producers and consumers of lead and zinc in the world. Lead and zinc mining and smelting can release hazardous heavy metals such as Cd, Pb, Zn, and As into soils, exerting health risks to human by chronic exposure. The concentrations of Cd, Zn, Pb, and As in soil samples collected from a PbZn mining area with exploitation history of 60 years were investigated. Health risks of the heavy metals in soil were evaluated using US Environmental Protection Agency (US EPA) recommended method. A geo-statistical technique (Kriging) was used for the interpolation of heavy metals pollution and Hazard Index (HI). The results indicated that the long-term Pb/Zn mining activities caused the serious pollution in the local soil. The concentrations of Cd, As, Pb, and Zn in topsoil were 40.3 ± 6.3, 103.7 ± 37.3, 3518.4 ± 896.1, and 10,413 ± 2973.2 mg/kg dry weight, respectively. The spatial distribution of the four metals possessed similar patterns, with higher concentrations around Aayiken (AYK), Maseka (MSK), and Kuangshan (KS) area and more rapidly dropped concentrations at upwind direction than those at downwind direction. The main pollutions of Cd and Zn were found in the upper 60 cm, the Pb was found in the upper 40 cm, and the As was in the upper 20 cm. The mobility of metals in soil profile of study area was classed as Cd > Zn ≫ Pb > As. Results indicated that there was a higher health risk (child higher than adult) in the study area. Pb contributed to the highest Hazard Quotient (57.0~73.9 %) for the Hazard Index.
