“…Most vein‐like gold deposits may undergo a complicated geological evolution during the source–transport–storage–change–preservation process (Goldfarb & Groves, ). Hydrogen and oxygen isotopes and fluid inclusions are good indicators of the evolutionary history of ore‐forming fluids, such as HO isotopes (McCuaig & Kerrich, ), rare gas, and halogen isotopes (Kendrick et al, ) and so on. We studied the HO isotopic composition of quartz veins during the different stages of the Zhuanshanzi gold deposit (Table.…”

“…CH 4 gas plays an important role in the precipitation enrichment of Au; it not only expands the temperature range of immiscibility of fluids, and it is also favorable for the precipitation of Au in ore‐forming fluids in a larger temperature range (Naden & Shepherd, ), but it also changes the redox state of the ore‐forming fluid and undergoes the following reactions ((1) and (2)), leading to a decrease in the stability of the gold complex, inducing the precipitation of Au (Kendrick et al, ).…”

The Zhuanshanzi gold deposit lies in the eastern section of the Xingmeng orogenic belt and the northern section of the Chifeng-Chaoyang gold belt. The gold veins are strictly controlled by a NW-oriented shear fault zone. Quartz veins and altered tectonic rock-type gold veins are the main vein types. The deposits can be divided into four mineralization stages, and the second and third metallogenic stages are the main metallogenic stages. In this paper, based on the detailed field geological surveys, an analysis of the orebody and ore characteristics, microtemperature measurement of fluid inclusions, the Laser Raman spectrum of the inclusions, determination of C H O S Pb isotopic geochemical characteristics, and so on were carried out to explore the origin of the ore-forming fluids, ore-forming materials, and the genesis of the deposits. The results show that the fluid inclusions can be divided into four types: type Igas-liquid two-phase inclusions; type IIgas-rich inclusions; type III-liquid inclusions; and type IV -CO 2 -containing threephase inclusions. However, they are dominated by type Ibgas liquid inclusions and type IVthree-phase inclusions containing CO 2 . The gas compositions are mainly H 2 O and CO 2 , indicating that the metallogenic system is a CO 2 H 2 O NaCl system. The homogenization temperature of the ore-forming fluid evolved from a middle temperature to a low temperature, and the temperature of the fluid was further reduced due to meteoric water mixing during the late stage, as well as a lack of CO 2 components, and eventually evolved into a simple NaCl H 2 O hydrothermal system. C H O S Pb isotope research proved that the ore-forming fluids are mainly magmatic water during the early stage, with abundant meteoric water mixed in during the late stage. Ore-forming materials originated mostly from hypomagma and were possibly influenced by the surrounding rocks, suggesting that the ore-forming materials were mainly magmatic hydrothermal deposits, with a small amount of crustal component. The fluid immiscibility and the CO 2 and CH 4 gases in the fluids played an active and important role in the precipitation and enrichment of Au during different metallogenic stages. The deposit is considered a magmatic hydrothermal deposit of middlelow temperature.Keywords: C H O S Pb isotope, metallogenic period and stage, microthermometry and laser Raman, ore-forming fluid, Zhuanshanzi gold deposit.

“…Future inclusion research will undoubtedly expand to take on new questions. Possible directions include age measurements of inclusion fluids (Wayne et al 1996), the use of biomarkers, noble gas isotopes and halogens to trace the source of inclusion fluids (Dutkiewicz et al 2006;Kendrick et al 2011), and the study of microorganisms in fluid inclusions (Naumov et al 2013).…”

Although fluid inclusions were apparently known to early naturalists, actual research on fluid and melt inclusions began only in the mid-1800s and grew very slowly for the next 100 years. Russian scientists began systematic studies of inclusions in the 1930s, but it was not until about 1960 that publications mentioning or using fluid inclusions began to increase from a few each year to the present annual level of about 700. Early research focused on ore deposits, first on temperatures and salinities of ore fluids and then on their stable isotopic and major element compositions. Later work extended to fluids in sedimentary and metamorphic environments. Publications using or mentioning melt inclusions only began to increase in number in about 1980 and have grown to today's level of about 200 per year. Early work on melt inclusions focused on igneous rocks with an emphasis on immiscibility and volatile elements and then on rare elements. Recent research on both fluid and melt inclusions has taken advantage of single inclusion analytical methods to investigate speciation and partitioning in both natural and experimental magmatic and aqueous systems.
