qaleh-zari is a fe-oxide cu-ag-au vein type deposit located 180 km south of birjand, in eastern iran. host rocks are mainly tertiary calc-alkaline to k-rich calc-alkaline with transition to shoshonitic andesite and andesitic basalts, but in the central part shale and sandstone of jurassic age. andesitic rocks from the western region of qaleh-zari were dated to 40.5 ± 2 ma. four trends of faults...

in the asemi-gawa area of intermediate high-pressure and low-temperature sanbagawa metamorphic belt in central shikoku, japan, piemontite-quartz schists are common in which cation exchange between piemontite and garnet has been studied. piemontite in contact with garnet usually contains two zones in which core is enriched in mn3+ and surrounded by a rim rich in fe3+. garnet is ca-fe-bearing spe...

in this paper, the vapor-liquid equilibrium (vle) properties of polar and nonpolar fluids are modeled by the use of a statistically-based equation of state (eos). the equation of state used in this work is that of ihm-song-mason (ism) eos. an alternative approach is to revise the isothermal integration on liquid. in this respect, a temperature-dependent revision factor b (t) is introduced to th...

Abstract The textures and geochemical characteristics of the rocks in layered intrusions potentially provide insights into physicochemical processes that have taken place mafic magma chambers. Diverse exsolution Fe-Ti oxides may record variation subsolidus temperature oxygen fugacity (fO2) cooling Here we investigated ilmenitehematite solid solution (Ilmss) relationships evident preserved inter...

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...

We describe occurrences of platinum-group minerals (PGM) and an uncommon mineral enriched in Cl, provide a brief review Cl-bearing associated with basic–ultrabasic complexes. An unusual phosphohedyphane-like phase (~30 µm), close to CaPb4(PO4)3Cl, occurs one the PGM-bearing veins massive sulfides Monchepluton layered complex, Kola Peninsula, Russia. These consist varying amounts pyrrhotite, pen...
