Lanthanide ions possess fascinating optical properties and their discovery, first industrial uses and present high technological applications are largely governed by their interaction with light. Lighting devices (economical luminescent lamps, light emitting diodes), television and computer displays, optical fibres, optical amplifiers, lasers, as well as responsive luminescent stains for biomed...

With >90 known deposits containing original reserves of >2400 Mt sulfide ore, the Iberian Pyrite Belt (IPB) is largest volcanogenic massive (VMS) province on Earth. In these evolving mineral systems, texturally different pyrite exhibits characteristic mineralogy and trace element fingerprints. (Py-1), which well preserved in polymetallic ores that crystallized at earliest stage VMS deposit form...

The Qin-Hang Metallogenic Belt (QHMB), an important metallogenic belt in South China, hosts Cu and W–Sn polymetallic deposits. Tongshanling ore field the QHMB is characterized by coexistence of Cu- W-bearing deposits, which are related to granodiorite granite porphyry. This study examined whole-rock geochemistry, geochronology, Sr–Nd–Hf isotopes determine genetic relationship between diverse or...

Fluorite is a widespread mineral in porphyry and hydrothermal vein Mo-polymetallic deposits. Here, fluorite utilised as probe to trace the fluid source reveal evolution process Chalukou giant Mo (Pb–Zn) deposit, Northeast China, which characterised early later vein-style Zn–Pb mineralisation. A detailed rare earth element (REE) Sr–Nd isotope study of combined with Sr isotopes sphalerite conduct...

Multi-stage magmatic events associated with large tungsten-tin polymetallic deposits in the Nanling Range have been subject of extensive research spanning many years. In this paper we report results a systematic study petrology, whole-rock geochemistry, zircon U-Pb chronology, and trace element geochemistry granite bodies exposed Xianghualing ore field. They show that granites area are characte...

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.

The method of bi-dimensional empirical mode decomposition (BEMD) and the combined methods entropy weight–Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) were used decompose gravity–magnetic data evaluate targets in Luziyuan Pb–Zn–Fe polymetallic ore field surrounding areas. Three meaningful intrinsic function (BIMF) images obtained BEMD at different wavelengths, depic...

The material source and the evolution of ore-forming hydrothermal fluids Xiaojiashan gold deposits remain controversial. We carried out a mineralogical characteristics analysis, trace elements sulfur isotope composition fluid inclusion microthermometry in order to explore sources, conditions, process this deposit. Gold mineralization can be divided into three stages: quartz-pyrite stage, quartz...
