N2 - The results obtained with LA-ICP-MS by less abundant lighter 113In isotope and EPMA show that in cassiterite of cassiterite-quartz veins the indium contents do not exceed 160ppm, while cassiterite from Sn-sulfide veins is characterized by higher indium contents from 40 to 485ppm; sulfides of Sn-sulfide veins unlike sulfides of cassiterite-quartz veins also have the highest indium contents: Fe-sphalerite (100-25,000ppm), chalcopyrite (up to 1000ppm), and stannite (up to 60,000ppm). Indium contents in the Sn-sulfide ore of the Tigrinoe and Pravourmiiskoe deposits obtained using SR-XRF, ICP-MS and atomic absorption methods range from 10 to 433ppm with average values of 56-65ppm. Indium-rich Sn-sulfide mineralization in five large Sn-Ag ore districts of the Far East Russia (Khingansky, Badzhalsky, Komsomolsky, Arminsky, Kavalerovsky) provides the impetus for further exploration of deposits with Sn-sulfide mineralization as the most promising indium resources in Russia. Empirical observations from geology and geochronology of cassiterite-quartz and Sn-sulfide mineralization show that the combined contribution from granite and alkaline-subalkaline mafic sources and multistage ore-forming processes doubled indium resources of deposits being the main factors in the formation of high grade indium mineralization.
