...O.M. Turkina; A.D. Nozhkin; T.B. Bayanova; N.V. Dmitrieva; A.V. Travin Abstract We studied geology and main rock assemblages of the Precambrian Kan, Arzybei, and Derba terranes of the Central Asian Fold Belt which border the Siberian craton in the southwest. The Precambrian terranes include three...

...) by the Dunzhugur oceanic island arc (1020 Ma, U-Pb age method) prior to the breakup of Rodinia [ 23 ]. Later (at about 800 Ma) the island arc thrust over the Gargan block on the passive margin of Siberia, was intruded by the Sumsunur collisional tonalites (785 Ma, U-Pb age method) and died out. As a result...

... accretionary-collisional structures were formed outside the PAO within certain cratonic blocks (microcontinents) belonging to other basins surrounding the Siberian craton ( Kheraskova et al., 2010 ; Kuzmichev and Larionov, 2013 ; Yarmolyuk et al., 2006 ), and therefore their assignment to the active margin...
