Abstract Most tungsten (W) and tin (Sn) deposits are associated with highly evolved granites derived from the anatexis of metasedimentary rocks. They commonly separated in both space time, rare cases where W Sn mineralization part a single deposit, two metals temporally separate. The factors controlling this behavior, however, not well understood. Our compilation whole-rock geochemical data for...

As a valuable mineral resource, uranium is extensively utilized in nuclear power generation, radiation therapy, isotope labeling, and tracing. In order to achieve energy structure diversification, reduce dependence on traditional fossil fuels, promote the sustainable development of production consumption, research metallogenic mechanisms related technologies resources has been one focuses China...

In this paper, constructing the improved chaotic map which multiplies output value of by a large value, and subtracts its integer part. Simulation results show that chaos range is enlarged. The generated sequence has strong randomness. A double image encryption algorithm proposed combining maps with permutation diffusion structure. can reduce complexity while ensuring effect. simulation resist ...

This paper describes native gold in ore-bearing breccias with realgar-orpiment cement from the Vorontsovskoe deposit (Northern Urals, Russia). Particular attention is paid to morphological features of and its relation other minerals. The latter include both common (orpiment, barite, pyrite, prehnite, realgar) rare species (Tl Hg sulfosalts, such as boscardinite, dalnegroite, écrinsite, gillulyi...

Cretaceous igneous rocks are concentrated in the northern Taebaeksan metallogenic region of South Korea, some which related to Fe skarns and/or hydrothermal vein Au–Ag deposits. However, detailed studies on emplacement age and magma source supplying this area lacking. In study, we investigated age, sources, geochemical characteristics seven around ore deposit, comparing them with previous studi...

A newly discovered Naomugeng lithium mineralization area is located to the east of Central Asian Orogenic Belt (CAOB). The hosted in volcanic rocks Manketou’ebo Formation. altered mainly consist quartz, orthoclase, chlorite, montmorillonite, calcite, and dolomite. Here, we present integrated studies petrography, mineralogy, geochemistry (with an average Li2O content 0.43 wt.%) collected from dr...
