UDC 553.24.065:(553.556:550.93)(235.222) PALEOHYDROTHERMAL ACTIVITY OF FAULTS IN THE GORNY ALTAI BASED ON TRAVERTINE DATING
G. G. Rusanov, E. V. Deev, Yu. M. Ryapolova, I. D. Zolnikov
The travertine findings imply paleo-hydrothermal activity of some faults in the southeastern, central and northeastern parts of the Gorny Altai. Most of these formations consist of carbonate material, cementing various types of loose deposits and turning them into conglomerates, breccias, gravelstones and sandstones. Additionally, the carbonate veins as well as travertine of both porous and pumice kinds are present, forming small bodies. The travertine radiocarbon age ranges from 34440±860 to 3475±35 years, which is within the end of Late Pleistocene – Holocene. Also two ages indicate travertine older than 40 000 years.
Key words: travertine, carbonate veins, 14C dating, active faults, the Gorny Altai.
