| Abstract: | Several active fault zones were studied in the southern Siberian Platform along the Kovykta–Sayansk–Irkutsk gas pipeline. Late Cenozoic seismogenic faults are observed here. The fault zone in the Biliktuika River valley shows the strongest displacements and deformations. The radiocarbon dating of buried soil horizons for this fault was compared with seismological data on the earthquakes observed in this area. The comparison permitted attributing the latest slip along the fault to the 25 May 1887 earthquake. |
