During the Triassic period, the Northeast Sichuan developed a huge evaporative salt layer and accumulated high quality deep potassium-rich brine. Due to the overall differences in tectonic depositional conditions, the genetic mechanism and enrichment...

The Triassic witnessed the significant potash formation in Sichuan Basin. So far, the main potash mineral reported is mostly polyhalite, while the origin of polyhalite in the fourth member of Jialingjiang Formation in eastern Sichuan Basin still rema...

The structural fissure and pore brine in western Qaidam Basin is the most important deep brine resources in China, and its causes have been debated over many years. In this paper, it discusses its geochemical causes by studying its major, trace eleme...

The survey of oil wells shows that deep brine containing useful elements such as lithium and potassium is widely distributed in the oil storage structure area represented by Nanyishan in the west of Qaidam. The brine is distributed from the Paleogene...

The Paleogene solid potassium salt mineralization has been found in the deep layer (5 141-5 218 m) of western Kuqa Depression, but it is still necessary to further study on the characteristics of gypsum-salt layer, potash conditions and potash-prospe...

Lop Nor is the largest single sulfate-type liquid potash deposit in the world, and the genesis of the deposit has been controversial. In this paper, the genesis of potassium-rich brine deposits in Lop Nor is discussed from the perspective of hydroche...

In order to understand the spatial distribution characteristics of ore-forming ions and the reason for high nitrate content in surface sediments of nitrate deposits in Kumishi Basin. In this study it focuses on the nitrate deposits in the basin, and ...

The material source and genesis mechanism of the potassium-rich brine in Jiangling Depression have not yet been ascertained. Mineralogical, petrological, geochemical analyses and water-rock reaction simulation experiments on Cenozoic basalts were car...

Massive Cretaceous-Paleogene evaporates with lithium (potash)-rich brines develop in Jitai Basin of South China, of which deep structural characteristics remain unclear so that no breakthrough progress has been made in the exploration and evaluation ...

Deep-seated K-rich brine is a very important potash resource. However, there are few systematic studies on the chemical characteristics and genesis of K-rich brine in sedimentary basins on a regional scale. The major and trace element analyses of the...

The Khorat Basin is an important potash basin in the Tethys metallogenic belt, but the exploration and development of potash deposits in this area are severely restricted due to the unclear deformation structure and the distribution rules of potash s...

There exist abundant potassium resources in Vientiane Basin of Laos. These huge evaporites or potash deposits are important materials for studying formation and evolution of ancient evaporites and seawater. The salt-bearing construction of the Vienti...

The study of ore-controlling structures is still weak in the Changjiang uranium ore field, which has restricted the understanding of metallogenic regularity and future prospecting direction. Through detailed analysis of ore-controlling structure in o...

The Shulouqiu uranium deposit is an important part of Changjiang uranium ore field. However, there are relatively fewer studies on its ore-forming fluid properties, source and metallogenic environment. Based on the characteristics of pyrite and other...

The Lujing uranium deposit located in the southwestern part of the Nanling metallogenic belt is a representative granite-related hydrothermal uranium deposit in South China. In this paperit presents new detailed fluid inclusion and H-O isotope data t...

The diabase dikes in the Huangsha U ore-field of South Jiangxi Province have close spatial relationship with U mineralization. The petrography, major element, trace element and Sr-Nd-Pb isotope analysis of diabase were carried out. The diabase is geo...

The high quality source rocks of the Chang 7 Member in Yanchang Formation of the Upper Triassic in the Ordos Basin are characterized by uranium enrichment, while the Jurassic-Cretaceous strata of the basin are famous for hosting a large number of san...

Xitian W-Sn polymetallic ore field is located in the middle part of the Nanning metallogenic belt, and multi-stage magmatism and W-Sn mineralization are developed in this ore field. To determine the spatial and temporal relationship between granites ...

There are great disputes about the metallogenic age, source of ore-forming material and genesis of the Tongchang copper-iron deposit, which limits the establishment of its metallogenic model and further prospecting practice. Re-Os isotope of chalcopy...

The Qinjiayu manganese ore in East Hebei occur mainly in manganese-bearing rock series at the bottom of the second member of the Mesoproterozoic Gaoyuzhuang Formation, however, the cause of manganese ore is unclear. In this paper, it uses microscopic...

The Sanshandao gold deposit, located in the northwest of Jiaodong district, is a super-large altered-rock type gold deposit. The lack of detailed studies of mineralogy and element geochemistry in this deposit limits the understanding of Au enrichment...
