...O.V. Lunina; A.S. Gladkov; A.M. Afonkin; E.V. Serebryakov Abstract The Mondy strike-slip fault connects the W–E Tunka and N–S Hövsgöl basins on the southern flank of the Baikal rift system. Ground penetrating radar (GPR) surveys in its damage zone provide constraints on thicknesses, dips...

...A.A. Shchetnikov Abstract The general basement subsidence trend in the Tunka rift is locally interrupted by uplift (basin inversion). The inversion uplift causes deformation to basin sediments and shows up in the surface topography as morphostructures of two types. Inversion in the area is either...

... on the western flank of the Tunka basin ( Fig. 2 ) (sections along the Irkut River and its right tributaries—Belyi Irkut, Srednii Irkut, and Aerkhan Rivers) (Shkol’nik et al., 2009 ). These metavolcanics were reconstructed as tholeiitic basalts and, partly, andesite-basalts and andesites, with geochemical...

... ± 573. The values of the quality factor and the attenuation coefficient are calculated for the whole southwestern flank of the Baikal rift system and for individual tectonic blocks: the stable Siberian Platform, Khamar-Daban and East Sayan uplifts, and South Baikal and Tunka basins. A comparison...

... zone beneath the Siberian craton. The Moho depth pattern fits the surface tectonic elements with thinner crust along Lake Baikal and under the Busiyngol and Tunka basins and thicker crust beneath the East Sayan and Transbaikalian mountains and under the Primorsky ridge on the southern craton border...

...Fig. 1. A . Main structures in Tunka system of basins. Abbreviations stand for names of structures, keyed as: MN — Mondy basin, HT — Hoytgol basin, TUR — Turan basin, TN — Tunka basin, TOR — Tory basin, BS — Bystraya basin; NIL — Nilov spur, EL — Elovka spur; KDL — Khamar-Daban link, BSL...

...Fig. 1. Scheme of the Tunka Rift and position of the sections of the study Quaternary sediments. 1 — intermontane basins; 2 — interbasinal bulkheads; 3 — mountain framing; 4–7 — position of the sections of complexes: 4 — sandy ( a — eolian sediments), 5 — boulder-pebble...

...A.V. Arzhannikova; C. Larroque; S.G. Arzhannikov We investigate the fault geometry and kinematics of Holocene active compressional structures in the Mondy basin and its surroundings (western termination of the Tunka system of rift basins) and continue the discussion on the M s = 7 Mondy earthquake...
