The Jinying gold deposit is located in southern Jilin Province in northeast China and is representative of the large Early Cretaceous gold deposits in this area. To better understand ore genesis of this deposit, a multi-isotope integrated analysis of U–Pb–Rb–Sr–He–Ar–S has been carried out.
The Southern Great Xing'an Range (SGXR) hosts a number of Early Cretaceous Sn and associated metal deposits, which can be divided into three principal types according to their geological characteristics: skarn type deposits, porphyry type deposits and hydrothermal vein type deposits. Fluid inclusion assemblages of different …

Skarn tungsten-tin deposits, veinlet-disseminated tungsten deposits, quartz-vein wolframite/scheelite deposits, tourmaline-quartz vein tin deposits, greisen tungsten-tin deposits, and granite-pegmatite niobium-tantalum …
USMIN MIneral Deposit Database - graphic of the information contained in the database. For mineral deposit data, although prospects are included, the emphasis is on deposits, mines, and districts. Our goal is to develop a national-scale, geospatial database that is the authoritative source of the most important mines, mineral deposits, …
For example, the tectonic settings of some ore deposits from the Chinese Altay Mountains, one important part of the southern Altaids, remain controversial. Whether these ore deposits formed in a continental margin, island arc, or back-arc setting is an issue that need to be tested by appropriate geodynamic models.
A total of 26 papers are selected for publication in this special issue in Lithos with the focus on: (1) Newly discovered giant Li- (Be-Rb) rare metal deposits related to pegmatites in China; (2) Rare metal mineralization associated with highly fractionated granite, and (3) Mineralogical approaches to examine ore-forming processes and ages …
The deposit formed from a combination of hydrothermal and syn-sedimentary processes. Sulfur isotopes, together with sedimentological, textural, mineralogical, and geochemical evidences, suggest that this deposit should be classified as a vent-proximal sub-seafloor replacement SEDEX ore deposit.
Here we focus on the genetic relationships between the uangou Pb-Zn-Ag vein deposit and the world-class Donggou porphyry Mo deposit, and discuss the potential implications from the spatial and temporal relationships between porphyry and vein systems in the southern North China craton.
The Sr–He–Ar isotopic and elemental evidence constraints on the ore genesis of the Zhaxikang Sb–Pb–Zn–Ag deposit in southern Tibet
Iridium, a rare precious metal, might be in Haiti's soil. Will the nation benefit or suffer more if mines are built for extraction of iridium and similar resources?
The Kenticha granite-pegmatite is the largest repository of rare metals (Ta, Nb, Li, and Be) known so far in the Horn of Africa (Tadesse 2001 ). The ore deposit of rare metals in the area occurs in three forms, notably.
Shihuiyao Rb–Nb–Ta-rich granites from the Late Jurassic period are newly discovered rare-metal-bearing granites found in the southern Great Xing'an Range, NE China. Further research of these granites may contribute to better understanding the petrogenesis of rare-metal granites and their associated mineralization mechanisms.
A variety of deposit-scale geometric and geologic features and factors strongly influence the size and/or grade of porphyry copper, sediment-hosted stratiform copper, and/or IOCG deposits. For example, development of major porphyry copper deposits/districts is favored by the presence of clustered alteration-mineralization …

Apatite fission track thermochronology of Cenozoic igneous rocks from porphyry copper deposits in the Gangdese belt of southern Tibet: Implications for cooling history and ore preservation
The Herenping gold deposit is a typical gold deposit in the Xuefengshan arcuate tectonic zone in the southern margin of the Yangtze Craton, and the major feature of the gold mineralisation in the zone is the varying degrees of tungsten and antimony mineralisation in the ore deposits.
The Mesoproterozoic stratabound deposits of the Namaqua Sector of the NNMP are all of similar age and terrane bounded. Their different characteristics are the result of relative position within a subduction related plate tectonic setting. The siliciclastic hosted deposits of the Aggeneys-Gamsberg Ore District are interpreted to have formed in a continental …

Zircon geochronological and geochemical study of the Baogaigou Tin deposits, southern Great Xing'an Range, Northeast China: Implications for the timing of mineralization and ore genesis
This paper reports newly obtained data on the mineralogy, geochemistry, and predicted reserves of the Shaumyan gold-base metal deposit in southern Armenia and the Kharvana occurrence of ore mineralization in northwestern Iran.
The rare earth element (REE) patterns of the primary ore zone shows slight enrichment in LREE with strong negative Eu-anomaly. From mineralogical assemblage, tectonic setting and geochemical signatures the genesis of Kenticha tantalite deposit is by partial melting of metasedimentary rocks predated the granite and pegmatite with later ...
It has been well established that metal and sulfur sources in mineral deposits can be very difficult to identify, especially for ore deposits hosted in sedimentary rocks. Using the world's largest Sb deposit at Xikuangshan in southern China as a case study, this study combined Hg isotopes and in situ sulfur isotope measurements to …
These two deposits are archetype examples of large Archean orogenic gold systems. The Dome mine, where the ore is centered on a folded unconformity between Tisdale volcanic rocks and Timiskaming sedimentary deposits, also illustrates the spatial relationship between large gold deposits and a regional unconformity.
The term mineral deposit bears no profitability implications. Ore not only refers to metals, or metal-bearing minerals (metallic ores), but also to many non-metallic minerals valued for their own specific physical or chemical properties, such as fluorite and asbestos that are classified as industrial minerals.
We conclude that most of the mineralization of the Katugin ore deposit occurred during the magmatic stage of the alkaline granitic source melt. The results of detailed mineralogical studies suggest three major types of ores in the Katugin deposit: Zr mineralization, Ta-Nb-REE mineralization and aluminum fluoride mineralization.
The ore geology, fluid inclusion, and oxygen and sulfur isotope investigations of Pb–Zn–Cu mineralized quartz veins and breccias at Abbasabad indicate that this deposit is an IS epithermal deposit.
Scandium (Sc), known as the 'miracle metal', has unique properties in material sciences, and is a critical resource in the world due to the low supply but wide applications in advanced technology. Despite not extraordinarily sparse in the Earth's crust, Sc is often dispersed and does not form ore deposits.
The Piaotang deposit is one of the largest vein-type W-polymetallic deposits in southern Jiangxi Province, South China. The coexistence of wolframite and cassiterite is an important feature of the deposit. Based on detailed petrographic observations, microthermometry of fluid inclusions in wolframite, cassiterite and …

The morphology and composition of uranium minerals and metal …
These soils developed on calamine mining waste (originating from the exploitation of calamines in the "Bolesław" open-pit) and calamine tailings (originating from ore washing, meaning the historical method of calamine enrichment in ore minerals) in the vicinity of the town of Olkusz in southern Poland.
It is important to find out whether the fluid evolution and ore genesis of the deposit are consistent with other hydrothermal vein-type Cu deposits. This has important theoretical significance for deeply summarizing the genesis of such vein-type Cu deposits.
