... of the middle Paleozoic complex of the Vilyui syneclise was argued by K.K. Levashov ( 1975 ), who defined two parallel rift zones: Markha–Linde and Kempendyai–Lungkha. The Vilyui paleorift was considered as one of the branches of a triple junction system of middle Paleozoic age ( Zonenshain et al., 1991...

It has been found that percentage of TiO 2...

... of the formation of the Vilyui paleorift. New data on the basic rocks of the Vilyui paleorift, their geochemistry, and the sequence of their formation are discussed by Tomshin et al. (2018) . The authors show that the basic rocks of the Vilyui paleorift formed for ~18 Myr (380.7–362.0 Ma) during the prolonged...

... by a peak at 363.4 ± 0.7 Ma. According to reconstructions of Zonenshain et al. (1991) , the Vilyui basin is part of the Middle Paleozoic three-branch rift system. However, according to Tret’yakov (2004) , it has a more complex structure and the configuration of the rift systems does not correspond...

The Middle Paleozoic rift-related structures are overlain by sheets of the Middle Carboniferous–Cretaceous sediments of the Vilyui syneclise, which...

One branch of the triple system is the Vilyui Rift and two others correspond to marginal ruptures which form the present-day eastern boundary of the Siberian paleocontinent. The Vilyui Rift extends for about 800 km having a width of 450 km. It is marked...
