The Cuonadong deposit is the first large scale Sn-W-Be rare polymetallic located in southern Tibet, China, where beryl main beryllium-bearing mineral. In this paper, crystals pegmatitic and hydrothermal vein orebody from Xianglin area of are research objects, marked as Beryl-I Beryl-II, they investigated by EPMA, LA-ICP-MS situ micro-X-ray diffraction (XRD). Data EPMA reveal that beryls alkalin...

The Western Qinling orogenic belt (WQOB) is one of the most important prospective gold districts in China, with widely distributed Indosinian intermediate–acidic intrusions. Liziyuan Au deposit a representative northern WQOB, hosting several sections spatially associated igneous rocks. hosted by meta-sedimentary volcanic rocks Cambrian–Ordovician Group and Tianzishan monzogranite. Two periods, ...

• Geochronology and petrogenesis of the ore-forming intrusions from Lietinggang-Leqingla deposit. Fe-Cu mineralization was controlled by mantle materials weakly fractional crystallization. An ancient crustal component extensive fractionation crystallization contributed to Pb-Zn mineralization. The deposit has magmatism conditions that allow iron-copper lead-zinc form simultaneously. is a repres...

We report indium, germanium, gallium, and other minor trace elements contents in sphalerite, chalcopyrite, galena, tetrahedrite-tennantite occurring skarn skarn-free (“Cordilleran”) polymetallic mantos vein ore bodies the Miocene porphyry-related Morococha District, Central Peru. Among investigated minerals, LA-ICP-MS measurements indicate that In Ga concentrate mostly sphalerite (Inter-Quartil...

The title compound, [Fe(C(5)H(5))(C(7)H(5)Cl(2))], represents a versatile building block for the preparation of π-conjugated redox-active compounds or polymetallic organometallic systems due to the presence of the electrochemically active ferrocenyl unit. It is therefore a potential starting material for the preperation of the corresponding alkyne. In the crystal, the alkenyl unit and the cyclo...

Large-scale, high-density geochemical explorations entail enormous workloads and high costs for sample analysis, but, early mineral exploration, absolute concentrations are not essential. Geochemists require ranges, dynamics of variation, correlations rather than accuracy. Thus, higher work efficiency lower analysis desirable exploration. This study comprehensively analyzed the reliability appl...

Abstract The Ediacaran-Cambrian (E-C) succession in South China records remarkable oceanic, biological and geochemical variations, but it was not well defined geochronologically, which hinders the interpretation of spatio-temporal seawater chemical architecture during time E-C interval. This study presents two Re-Os isochron ages 520.2 ± 6.1 561.7 8.5 Ma for barite-rich black shales from top Li...
