A strategy for establishing the supply chain of tin, which is used in various industries, necessary because tin’s and demand are highly dependent on a few countries. Focusing Mongolia as resource-rich country, this study examines current state tin mineral resources characteristics mineralization according to tectonic environment. The magmatic activity that occurred from Late Paleozoic Mesozoic ...

The Malayer-Boroujerd-Shazand district (approximately 70 km long) is located in the Sanandaj-Sirjan zone with NW-SE trending, and consist mainly of hornfels, schist, phyllite, migmatite, granite and granodiorite which contain numerous pegmatite and aplitic dykes. Among these rocks, granodiorite, hornfels and schist are main host rocks for quartz, feldspar, muscovite and tourmaline bearing pegma...

Pyralespite garnet group (Almandine group) is common minerals in the metamorphic and igneous complex of Boroujerd area. Moreover, Almandin (Fe enriched garnet) is the most common mineral but the content of Spessartin (Mn enriched garnet) is high in this area. The changes of mineral composition in different grains show that these minerals are zoning chemical and core to rim composition is varied...

The Tonggou deposit is a porphyry Cu and vein-type Cu-Zn mineralization system located in the Bogda Orogenic Belt, north of Eastern Tianshan. Systematic fluid inclusion analyses were performed on granular quartz from magnetite–quartz stage pyrite–chalcopyrite–quartz mineralization. During early mineralization, ore-forming fluids at high temperatures (450–501 °C) salinity (51.2–55.2 wt.% NaCl eq...
