Paleoseismicity in Cis-Baikal Rift Basins: Evidence and Age Constraints

摘要

Recent years have witnessed considerable advances in the study of deformation structures caused by soil liquefaction during seismic shocks [1-5]. These structures are clear paleoearthquake indicators [2] that can be used for determining various parameters of past events [3-5]. This paper deals with identification, structural and geological study, and dating of the sections that contain seismites, clastic dykes, dislocation cracks, and paleosols buried as a result of rapid tectonic downthrows in the Tunka and Barguzin valleys of the cis-Baikal Area (Fig. 1).
