Abstract
In the north of the East European Platform, placer deposits of titanium minerals are known only within the Timan fold-block uplifts separating the Pechora and Russian plates. The only occurrence of titanium-bearing placers in the north of the Russian Plate, the Chuplega ore occurrence, was discovered in the core of a borehole drilled 80 km east of the city of Arkhangelsk in the contour of the cognominal arched uplift. Titanium-bearing sandstones in the Upper Vendian terrigenous sequence, penetrated at a depth of 171.4–71.5 m, contain ilmenite and its transformation products: leucoxene, rutile, anatase, brookite. TiO2 concentrations in them vary from 1.32 to 6.1%. The article presents the geological, lithological, mineralogical, and geochemical characteristics of the ore occurrence and the results of the U-Pb isotope study of detrital zircons obtained for the first time. The datings of zircon from the Chuplega placer are very similar to those from the Timan deposits (giant Yarega oil-leucoxene and large Pizhma ilmenite-leucoxene).
The Chuplega ore occurrence is a direct indication of the presence of commercial titanium-bearing placers in the depths of the northern part of the Russian Plate. They can occur at depths (to 200 m) accessible for open-pit mining.
