ЭКЗОГЕННЫЙ МОРФОЛИТОГЕНЕЗ ЗОНЫ СЕЗОННОЙ ОСУШКИ КАМСКИХ ВОДОХРАНИЛИЩ
НАЗАРОВ Н.Н. — 2010 г.
Geomorphological effect of exogenic processes on the coastal shallows of the Kama water reservoirs during the formation of seasonal mud flats is comparable in several years to activity of hydrophysical processes at normal lockup levels. Deflation-aeolian processes may cause the increase or decrease of the height of a shallow on separate sites by 0.25-0.40 m during the short periods of time (from one to three weeks). Influence of temporal melt-water currents on a surface of a coastal slope is usually leads to formation of gullies and ravines up to 1.5 m depth and more. Weathering, most notably manifested on abrasion surfaces build up by the dense low-plastic clay, results in the formation of the deep cracks, which are gradually extending under action of a deflation or up-wash and turning into crest-like forms up to 0.3-0.4 m height. The geomorphological effect of frost grounds manifests on the sandy- siltstone deposits underlaid by rocky debris. Owing to differences in a thermal capacity of large shatters and fine deposits there appear little hubbles on the surface of a shallow up to 0.3-0.5 m in diameter and 0.15-0.20 m in height. Depth of the plucking of the coastal slopes by gravitational displacement of an ice or by trash ice can reach 0.3-0.4 m and its width - 5-7 m.

ВЛИЯНИЕ ПРОЧНОСТНЫХ ХАРАКТЕРИСТИК ГРУНТОВ НА ИНТЕНСИВНОСТЬ РУСЛОВЫХ ДЕФОРМАЦИЙ В СРЕДНЕМ ТЕЧЕНИИ Р. ДЕСНЫ
БАСТРАКОВ Г.В., ЛОБАНОВ Г.В., СМИРНОВА Е.А. — 2009 г.
The resistance of river bank ground to erosion (washing) depends on granulometric composition, density, the degree of consolidation, rootage development. The impacts of these factors were evaluated. The riverbed lateral displacement velocity was analyzed as function of channel-fill deposits, morphogenetic, and morphodynamic types of channel, the middle reach of Desna as an example.

ВЛИЯНИЕ СЕЛЕЙ НА ФОРМИРОВАНИЕ И ДИНАМИКУ РУСЛООБРАЗУЮЩИХ НАНОСОВ ГОРНОЙ РЕКИ (НА ПРИМЕРЕ Р. БАКСАН)
ВИНОГРАДОВА H.H., КРЫЛЕНКО И.В., ТАРБЕЕВА A.M. — 2009 г.
The granulometric characteristics of the mountain river Baksan channel deposits and their dynamics are analyzed at the points of the falls of the mudflow tributaries. The dependence on longitudinal profile, channel morphology, frequency and volume of mudflows is taking into account. Changes of granulometric composition are examined immediately after the mudflow events and between them.

ВРЕМЕННАЯ ОРГАНИЗОВАННОСТЬ ДВУХ АРИДНЫХ ГЕОМОРФОЛОГИЧЕСКИХ СИСТЕМ
ПЕРЕСЛЕГИНА Р.Е., ТИМОФЕЕВ Д.А. — 2009 г.
Authors conceive the time organization of geomorphologie system as an ordered and concerted existence and functioning of the system's elements during certain time. It is also a directional development of system, sequence of stages and phases of evolution. The problem is considered on the example of two arid geomorphologic systems -badlands in the foothill of Terskey-Alatow ridge (Tien-Shan) and gammada in the South of Mongolia. It is shown that morphology, contemporary processes, lithochemical conditions, and the surface runoff types are closely correlated and tend to maintain systems in the state of dynamic equilibrium.

ВЫСОКАЯ КАРАНГАТСКАЯ ЛАГУННО-ТРАНСГРЕССИВНАЯ ТЕРРАСА КЕРЧЕНСКОГО ПРОЛИВА
БАДЮКОВА Е.Н. — 2009 г.
The structure is analyzed of loess rock mass that builds up the top of the section near Georgievskoye village on Kerch Peninsular. The author supposes the alluvium-lagoon genesis of this rock mass. Typical marine Karangad deposits in the bottom of the section correspond to one of the first transgressive phase of the Black Sea. The consequent maximum transgression (Karangad) up to 15-20 m marks many shores of the Black Sea as lagoon-transgressive terraces and correlated river embouchment terraces.

ГЕОГРАФИЧЕСКОЕ РУСЛОВЕДЕНИЕ И МОРФОДИНАМИКА РЕЧНЫХ РУСЕЛ
ЧАЛОВ Р.С. — 2009 г.
The justification of the geographical river-bed study as substantive research field is founded. The structure of this study is under consideration. Special attention is paid to its component - river-bed morphodynamics that deals with river-bed morphology, river-bed deformation and water regime, technogenic changes of river-bed processes and forms, hydromor-phological interrelations between river-bed forms parameters and factors of river-bed processes. The connections of riverbed morphodynamics with flood-plane study, longitudinal profile theory, and studies of factors and conditions of river bed processes.

ГЕОМОРФОЛОГИЧЕСКАЯ КОНВЕРГЕНЦИЯ
УФИМЦЕВ Г.Ф. — 2009 г.
Geomorphologic convergence denominates the morphological similarity of landforms of different genesis. The concept of temporal convergence leads to special attention to genesis as complex characteristic. Some examples of morphological convergence are given as well as methodology of its detection.

ГЕОМОРФОЛОГИЧЕСКАЯ ОПАСНОСТЬ АКТИВНЫХ РАЗЛОМОВ
КУЗЬМИН С.Б. — 2009 г.
The evaluation of the geomorphologic hazard of active faults was made in the region of Sayan-Shusha waterpower (west Sayan) and in the South and Middle Cisbaikaline. Active faults are strong factor of geomorphologic hazard. It may really cause the geomorphologic risk for human activity, extremely hazardous situations, and natural disasters. The density of faults may serve as the criterion for assessment of geomorphologic hazard.

ГЕОХРОНОМЕТРИЯ КАЙНОЗОЙСКОГО ГОРООБРАЗОВАНИЯ В АЛТАЕ-САЯНСКОЙ ОБЛАСТИ ПО ПИРОМЕТАМОРФИЧЕСКИМ КОМПЛЕКСАМ: ГЕОЛОГИЧЕСКОЕ ОБОСНОВАНИЕ
НОВИКОВ И.С., СОКОЛ Э.В. — 2009 г.
Melted pyrogenic rocks - paralavas - are analogous to magmas regarding their certain mineralogical and geochemical characteristics. Present methods of volcanic rocks radiometric dating may be used for the absolute dating of coal fires. Petrologic study of pyrometamorphic complexes was fulfilled in the Prokop'evsky-Kiselevsky region of Kuzbass; some rock groups were shown to be applicable for such dating. First radiometric datings were obtained: older group - 1.22 ± 0.44 Ma (40Ar/39Ar) and 1.8 ± 0.2 (K/40Ar) - is represented by rocks from the block between the Tyrgansky thrust and Afonin-Kiselevsky overlap fault. Another, younger group - 0.19 ± 0.26 Ma (40Ar/39Ar) and 0.48 ± 0.11 Ma (K/40Ar) - consists of paralavas from the more eastern block between Afonin-Kiselevsky and Kiselevsky overlap faults. These datings correspond to main stages of neotectonic activization of the boundary between the Salair and Kuznetsk basin because the coal fires were contemporised to the uplifts of the territory and to the putting the coal into the zone of aeration.

ГОЛОЦЕНОВАЯ АКТИВНОСТЬ РАЗРЫВНЫХ СТРУКТУР ЮГО-ВОСТОКА ЗАПАДНОЙ СИБИРИ, ЕЕ ПРОЯВЛЕНИЕ В РЕЛЬЕФЕ И СТРОЕНИИ АЛЛЮВИАЛЬНЫХ ОТЛОЖЕНИЙ
ШВАРЕВ С.В. — 2009 г.
The structure of flood plain alluvial deposits in one of the river valleys in the south-eastern part of Western Siberia represents numerous forms of wave-type and flexural deformations and liquefaction (intralayer folding). The river valley corresponds to fault identified on remote images and extended 150 km in north-eastern direction. These deformations indicate the middle or late Holocene earthquake, which causes local displacements of flood-plain surface.

СВИТОЧ А.А., ХОМЕНКО А.А. — 2009 г.
Ridge type landforms are abundant in the Manych depression and have erosion origin. They consist of layered burtassko-gudilovsky lacustrine deposits and were formed stepwise during the end of burtasskoye time, in the epoch of Khvalyn strait and in the post-Khvalyn time.
