This paper is the first attempt to study mineralogical and geochemical features of mineralization hosted within volcanic rocks Baska Piwaza section, at Halgurd Mountain, which highest mountain in Kurdistan whole Iraq. The host lithologies studied section represent mostly (basalts andesites), secondary sedimentary lithologies, such as radiolarian chert. There are two main stages oxide sulfide th...

Abstract The Niederschlag fluorite-barite vein deposit in the Western Erzgebirge, Germany, has been actively mined since 2013. We present results of a first comprehensive study mineralogy, petrography, fluid inclusions, and trace element geochemistry fluorite related to deposit. Two different stages mineralization are recognized. Stage I is older, fine-grained, associated with quartz, forms com...

Using a combination of microstructural, spectroscopic, and geochemical analyses, we investigate how subgrain rotation recrystallization fluid migration affect Ti concentration [Ti] in naturally deformed quartz veins from the Prijakt Nappe (Austroalpine Unit, Eastern Alps). These coarse-grained veins, that formed at amphibolite facies conditions, were overprinted by lower greenschist deformation...

Abstract Orogenic gold deposits formed in various terranes of most ages since the Paleoarchean and generally consist quartz veins hosted shear zones at ductile brittle transition under greenschist to lower amphibolite metamorphic conditions. Vein mineralogy is dominated by with amounts silicates, carbonates, phyllosilicates, borates, tungstates, sulfides, oxides. The isotopic composition these ...

It is recognized that magmatic activities have occurred along the Izmir Erzincan suture due to closure of Tethyan ocean. In western part Almus (Tokat), which situated around this zone, quartz veins fracture lines are observed in volcanics owing magmatism. There copper enrichments with an average thickness 70 cm volcanic rocks. Mineralization as vein type and epigenetic formation. Paragenesis co...

Abstract Situated in the western Erzgebirge metallogenetic province (Vogtland, Germany), Eichigt prospect is associated with several quartz-Mn-Fe-oxyhydroxide veins that are exposed at surface. Bulk-rock geochemical assays of vein material yield high concentrations Li (0.6–4.1 kg/t), Co (0.6–14.7 and Ni (0.2–2.8 as well significant quantities Mn, Cu, light rare earth elements, a very unusual me...
