Garnet-type solid-state electrolytes have attracted extensive attention due to their high ionic conductivity, approaching 1 mS cm-1, excellent environmental stability, and wide electrochemical stability window, from lithium metal to ∼6 V. However, to date, there has been little success in the development of high-performance solid-state batteries using these exceptional materials, the major chal...
Solid-state batteries are a promising option toward high energy and power densities due to the use of lithium (Li) metal as an anode. Among all solid electrolyte materials ranging from sulfides to oxides and oxynitrides, cubic garnet-type Li7La3Zr2O12 (LLZO) ceramic electrolytes are superior candidates because of their high ionic conductivity (10-3 to 10-4 S/cm) and good stability against Li me...
Gazu copper deposit is located in the boundary of Tabas and Lut block, 65km southeast of Tabas and 15km southwest of Deyhouk. The dominant lithology in the area consists of Shotori dolomite and limestone and Shemshak shale and sandstone. Intrusive rocks with intermediate composition are widespread and numerous in the area. They consist of diorite, monzonite, and quartz monzonite to granite. Mi...
The source of iron material and the mineralization process skarn deposits within eastern North China Craton are ambiguous. In this study, we present new mineral chemical data Jinling deposit, located in western Shandong Province, east China. Based on petrography study data, suggest that deposit is hydrothermal metallogenic enriched by leaching Fe-rich fluids derived from primitive magmatic melt...
The emplacement of Oligo-Miocene age Sheyvardagh intrusive body within the older carbonate and volcanoclastic rocks is responsible for contact metamorphism and creating of Mazraeh deposit in epidote - garnet exoskarn of Western Alborz- lesser Caucasus metallogenic belt. Mineralogical paragenesis consist of magnetite, pyrite, chalcopyrite, bornite, covellite, hematite, goethite and malachite and...
Geochemistry and fluid inclusions studies were carried out on garnet and beryl from Quaternary alluvium deposits of Meluli-Namuhuca area, Mozambique. Garnet occurs as euhedral large crystals and is commonly brownish red, with a moderate brown hue in transmitted light. Apatite and ilmenite are the common inclusions. Geochemically, garnet is characterized by nearly homogenous chemical composition...
• 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...
An undeformed metadolerite dyke cutting foliated pyroxene-granulite facies gneisses in the Jotunhelm, Norway, has almandine rods replacing the cores of plagioclase laths, although garnet is generally absent from the enclosing gneisses, and is not present in reaction zones between peridotites and gneisses. Chemical analyses of the dyke and its garnet, plagioclase, and clinopyroxene are given. Th...
The structural phase transition of gadolinium-scandium-gallium garnet (Gd(3)Sc(2)Ga(3)O(12), GSGG) has been studied at high pressure and high temperature using the synchrotron X-ray diffraction technique in a laser-heated diamond anvil cell. The GSGG garnet transformed to an orthorhombic perovskite structure at approximately 24 GPa after laser heating to 1500-2000 K. The garnet-to-perovskite ph...
