Glacier-dammed lakes and geological work of glacial superfloods in the Late Pleistocene, Southern Siberia, Altai Mountains

Quaternary glacier-dammed lakes of Southern Siberia produced cataclysmic superfloods-floodstreams at the initial and final glacial stages, when the ice dams were unstable. Consequently, the initial surface was greatly and geologically instantly transformed. Morphologic associations of mountainous scablands developed, similar to the diluvial complexes ofthe Channeled Scabland in North America: giant diluvial ramparts and terraces-bars, diluvial berms and giant current ripple relief. Diluvial-erosional and evorsional forms, including spillways, outburst and oversplash gorges, and ‘‘dry waterfalls’’ are also present. The discharges of the glacial superfloods, which have been calculated by independent methods, were hundreds ofcubic meters per second at the locations where the giant current ripple marks were formed, up to millions of cubic meters per second within the gorges. Maximum discharges of 18 ×106m3/s were characteristic of the diluvial floods in the runoff channel from the Chuya–Kuray system of the glacierdammed lakes below the mouth ofthe Kuray depression as far as the settlement of Chibit. The power ofthose floods reached 106W/m2. These values exceed the hydraulic parameters of the jokulhlaups from Late Quaternary Lake Missoula in North America, the floods of which previously were considered the most powerful freshwater streams in Earth history. The last phenomenal glacial superflood with discharges in excess of 1×106m3/s occurred in the Chuya and Katun valleys no later than 13 000 years ago. Afterwards, the glacier-dammed lakes degraded simultaneously with the degradation of the glaciers. The glacier-dammed lakes ofthe intermontane basins in Southern Siberia disappeared completely at some time after 5000 years ago. Calculations of the hydraulics and the estimates ofthe geological activity of the Quaternary jokulhlaups mean that the diluvial processes of relief formation can now be viewed as the most powerful exogenous process.

1. Introduction_20110503_1318694566

 All ofthe mountains from Eastern Kazakhstan (Tien Shan, Kazakh Altai) to the mountains in the Baikal region belong to the mountains of Southern Siberia, which also includes those of Altai and Tuva. This grand mountainous chain forms a part of the Russian State boundary in the south. The Altai is located near the centre of Asia and is the highest of all mountain ranges in Siberia (some ofthe maximum measured elevations are over 4000 m). The Altai Mountains consist of vast intermontane basins, which were occupied by near-glacial lakes in the Pleistocene, and of high mountain ranges that carry the grandest of modern Siberian glaciers. Numerous climatic zones, which are also peculiar to a certain extent to the neighbouring mountainous countries, are present. The nival-glacial zone changes downwards into the taiga and tundra, into the steppes and the deserts of high-mountain basins, which in turn are adjacent to the mixed woods zone and the zone of South-Siberian steppes. That is why, from the viewpoint of physical geography, the Altai may be considered representative of the whole huge mountainous region of Southern Siberia. From the palaeogeographical and geomorphologic aspects, the Altai is typical of the whole of Central Asia.

It is in the Altai that a number of great scientific discoveries have been made during the last decades, which are important for Russian and world-wide Geomorphology, Palaeoglaciology and Quaternary Geology in the 20th century. The chief ones are:

(1) Discovery and identification of geological-geomorphological traces of giant Late-Quaternary glacier-dammed  lakes whose regular outbursts resulted in generation of glacial superfloods. Those floods left behind exotic relief forms and deposits (in the first place, giant current ripple marks and diluvial swells and terraces-‘‘bars’’according to Bretz, 1923), similar to the diluvial morpholithologic associations of the Channeled Scabland in North America; and

(2) Discovery of the geological phenomenon of Quaternary Ledoyoms-huge amounts of ice in the intermontane basins. Those ice bodies have a very complicated paragenetic relationship with glacier-dammed lakes (Rudoy, 1991, 1998). The present article deals with the problem of geological and geomorphological effects of the Quaternary jokulhlaups, and that of palaeohydrology and hydraulics of the glacier-dammed lakes and glacial superfloods.

If your goal is to be that guy that commands attention,
gets the best looking girl, lands the best job and has the
