... of 198 tons in the Kyzyk-Chadr deposit, and the East Tannu-Ola ore district with gold resources of 68.3 tons. Thus, the intricate geologic development of the Tyva area and various geologic events, including large-scale magmatic processes, led to the formation of both gold and gold-bearing deposits...

... is taken as Early Devonian, based on the presence of pebble of mineralized porphyraceous granodiorites in the Atakshil Formation conglomerates ( Mironyuk et al., 2012 ; Glukhov, 2013 ). Southeast of the ore district, there is the large Kadyr-Os granitoid pluton of the middle Cambrian Tannu-Ola complex...

... and Middle Paleozoic granite and granite–diorite magmatism, namely, the Tannu-Ola, Martaiga, and Ust’-Belovskii igneous complexes ( Shokal’skii et al., 2000 ). Skarn formation is associated with early stages of contact metamorphism. The formation of ore mineralization was longer and more complicated...

..., Fedorovskoe), Gornaya Shoriya (Maisko-Lebedskoe), and Tuva (Tardanskoe, Khopto). Most of them are commercial ( Fig. 1 ). These deposits resulted from the Early-Middle Paleozoic granite and granite-diorite magmatism (Tannu-Ola, Martaiga, and Ust’-Belaya intrusive complexes) [ 3 ]. Skarns were produced...
