Реферат:	eng: First Th-230/U-dating results have been obtained for six Quaternary travertine deposits from the southeastern Gorny Altai associated with zones of active faults that bound the Chuya and Kurai intermontane basins. The travertines consist mainly of calcite (with minor aragonite), which cements alluvial, alluvial fan, and colluvial deposits. The travertines dated at 1.3, 4.9, and 6.3 ka BP were related to large (M-w = 6.5-6.9) paleoearthquakes. The age of an 11 ka BP travertine falls into the 8.5 to 16 ka BP interval of high seismicity in the region. The 123 ka BP travertine results from slip triggered by the Middle Pleistocene deglaciation, while that of 400 ka BP represents seismic motions during the main Cenozoic orogenic phase.
