Pucheng district is a part of the Wuyi Mountain polymetallic metallogenic belt, which constituted by Archean-Proterozoic metamorphic basements and Mesozoic volcanic-sedimentary covers. Uranium deposits are formed as volcanic-hosted structural controls. In this study, hybrid data-driven methods logistic regression (LR) weights evidence (WofE) were applied for mineral potential mapping uranium in...

Microbacterium profundi strain Shh49(T) was isolated from deep-sea sediment from a polymetallic nodule area located in the East Pacific Ocean. Strain Shh49(T) contains genes related to the reduction/oxidation of metals. It has potential application in the bioremediation of heavy metal-contaminated environments.

In the Marrakech region of Morocco, where water resources are particularly limited, excessive salinity has been measured in from some wells intended for human consumption and irrigation. Moreover, start-up a mine exploitation polymetallic sulfide deposit progress work have revealed existence very saline deep groundwater with total mineralization over 80 g/L. The hydrogeochemical study using con...

The mining district of Nefza-Sejnane (Tunisia) encloses numerous ores and raw material deposits, all formed in relation with successive Fe-rich fluids meteoric and/or hydrothermal origins. Here, for the first time Tunisia, (U-Th)/He ages were obtained on supergene goethite from various localities/deposits highlight direct dating significant weathering episodes during late Tortonian Pleistocene....

Abstract The Ruwai skarn deposit is the largest polymetallic in Borneo and located Schwaner Mountains. skarns massive orebodies are hosted marble of Jurassic Ketapang Complex, which was intruded by Cretaceous Sukadana granitoids. prograde-stage garnet retrograde-stage titanite yielded U-Pb ages 97.0 ± 1.8 to 94.2 10.3 Ma 96.0 2.9 95.0 2.0 Ma, respectively. These similar Re-Os obtained on sulfid...

Commercial-scale mining for polymetallic nodules could have a major impact on the deep-sea environment, but the effects of these mining activities on deep-sea ecosystems are very poorly known. The first commercial test mining for polymetallic nodules was carried out in 1970. Since then a number of small-scale commercial test mining or scientific disturbance studies have been carried out. Here w...

BACKGROUND There is growing interest in mining polymetallic nodules from the abyssal Clarion-Clipperton Zone (CCZ) in the tropical Pacific Ocean. Despite having been the focus of environmental studies for decades, the benthic megafauna of the CCZ remain poorly known. To predict and manage the environmental impacts of mining in the CCZ, baseline knowledge of the megafauna is essential. The ABYSS...

The use of mineral resources has always been critical for human development [...]

• Skarn-type mineralization of the Cuonadong Sn-W-Be polymetallic deposit occurred at ca. 15 Ma. Skarn-hosted scheelite can be divided into an older type 1 and a younger 2 scheelite. The ore-forming fluid was exsolved from Miocene leucogranite. Geochemically isotopically, modified by intense fluid-rock interaction during skarnization greisenization. is first rare-metal with extraordinary metall...

introduction the mn mineralization occurs in the northeastern segment of the sabzevar zone (sz), north of the central iranian microcontinent (cim). this zone (sz) is located between the cim fragmentation in the south and the kopeh dagh sedimentary sequence in the north. the ore deposits of the northeastern segment of the sabzevar zone can be divided into three groups, each with different metal ...
