New about titanium content in the Yarega ore cluster (Southern Timan)

Yarega oil­titanium giant field is considered comprehensively. Details of previously unknown four shows and six points of titanium mineralization in the cognominal ore cluster are first given. Two distinct in productivity ore zones are predicted. These materials enabled to evaluate the total estimated titanium dioxide resources (P3 grade) in Yarega ore cluster as equal to the proven reserves in the giant field. The ore cluster incorporates two genetic types of placers. The largest placers are confined to the Chibyu formation, are of Givetian age and associated with alluvial environment. Frasnian placers in terrigenous beds of the Dzhyer formation and in younger sediments directly on Baikalides are referred to coastal­marine ones.
