Introduction Jiaodong is the most prolific gold province in China Based on the spatial distribution and structural characteristics of gold deposits the province can be divided into three ore belts from west to east the Laizhou Zhaoyuan Pingdu Penglai Qixia and Muping Rushan Chen et al 1989 The Jiaodong gold deposits are usually divided into three types

The Yanbian mining district is located in northeast China within the giant metallogenic belt on the western coast of the Pacific Ocean Fig 1 A and it is one of the most significant porphyry epithermal Cu Au mining districts on the continental margin of east China Shan et al 2021 Sun et al 2006 Sun et al 2013 The Ganhegou gold deposit is located in
The Baishawo deposit is a newly discovered large pegmatite type Be Li Nb Ta deposit that located at the NE Hunan province South China with estimated reserves of 16 160 t BeO % 11 280 t
Lithium Li ore is a type of rock or mineral that contains significant concentrations of lithium a soft silver white alkali metal with the atomic number 3 and symbol Li on the periodic table Lithium is known for its unique properties such as being the lightest metal having the highest electrochemical potential and being highly reactive with water
The Baoginshan quartz vein type gold mine in the Baimashan Longshan Ziyunshan gold belt is the object of study and the nature of the fracture structure and its ore controlling effect are studied
Jian Wei Li; Andrew G Hunt; Precise constraints on the source and evolution of ore forming fluids of Carlin type gold deposits in the Golden Triangle south China are of critical importance for
The Wangu gold deposit shares many geological and geochemical similarities as well as differences with typical orogenic epithermal and Carlin type gold deposits and may be better classified as
Gold deposits in Jiaodong Peninsula are mainly divided into two types lode gold quartz sulfide veins Linglong type and shear zone hosted disseminated sulfides in granitoids Jiaojia type Both types of gold deposits are similar in geology and geochemistry Lü & Kong 1993; Deng et al 1996; 2003; 2006; Qiu et al 2002; Yang et al 2004
Here we present He Ne and Ar isotope data of fluid inclusion extracts from a variety of ore and gangue minerals arsenian pyrite realgar quartz calcite and fluorite representing the main and late ore stages of three well characterized major gold deposits Shuiyindong Nibao and Yata to provide significant new insights into the source
Among them superimposing mineralization is a common feature and often a key to form high quality lode gold deposits including the superimposition of 1 multistage orogenic gold mineralization such as the Laowangzhai type gold deposits in the Sanjiang Tethyan Orogen in southwestern China Yang et al 2010 Yang et al 2011 Deng et
The fluids ascended to the Wulong and Sanguliu intrusions along NNE SSW and NNW SSE trending faults where temperature and pressure dropping water wallrock reactions and fluid immiscibility generated the vein type Wulong deposit The gold deposits in the Wulong orefield share many similarities with the Linglong and Jiaojia type gold

Detailed fieldwork revealed that the deposit has mainly undergone four deformation events The ore bodies developed in NE trending dextral oblique slip reverse faults of D 3 that crosscut WNW trending shear zones of D timing and corresponding stress regimes of the D 3 event suggest that it formed in a local extensional environment of Yanshanian
related gold IRG type Li et al 2023 Specifically there is a debate on whether the gold deposit were formed from magmatic hydrothermal fluids or metamorphic hydrothermal fluids One of the main reasons for the uncertainty in determining the source of ore forming fluids is the wide range of changes in the composition of H O S
The Xiejiagou gold deposit located in the Zhaoyuan Laizhou gold belt is composed of altered rock type gold mineralization and superposed auriferous quartz veins showing unique two stage gold
Carlin type gold deposits are among the most important gold bearing hydrothermal ore systems and are mainly located in Nevada USA and southwestern China However the source and evolution of the ore forming fluids for these deposits remain controversial especially those found within China In this study lithium and oxygen isotopic
These chemical zonations in pyrite have been recognized in a variety of hydrothermal ore deposit types porphyry Cu Mo Au epithermal Au deposits iron oxide copper gold Carlin type
The Linglong goldfield historically best recognized solely for its Linglong type gold deposits is now known to also host Jiaojia type gold deposits following discovery of the Taishang Luoshan and Dongfeng deposits during the past few decades Li and Yang 1993 Wen et al 2015 Deposits such as Taishang Luoshan and Fushan host both
The fluids ascended to the Wulong and Sanguliu intrusions along NNE SSW and NNW SSE trending faults where temperature and pressure dropping water wallrock reactions and fluid immiscibility generated the vein type Wulong deposit The gold deposits in the Wulong orefield share many similarities with the Linglong and Jiaojia type gold
