СОВРЕМЕННАЯ БЛОКОВАЯ СТРУКТУРА ЗЕМНОЙ КОРЫ ИСЛАНДИИ
ГЛАСКО М.П. — 2013 г.
Using the formalized method of morphostructural regionalization the map of recent block structure of the Iceland and surrounding shelf in the scale of 1:300000 was compiled. The Iceland megablock is divided into two macroblocks, which are separated by large morphostructural lineament corresponding to the rift zone. Radial disjunctives extend from continental part to the shelf of Iceland. Large volcanoes and epicentres of high magnitude earthquakes are attached to the elements of block structure. This connection may be used for determining of extreme events locations. The Iceland with its shelf and continental slope may be considered as intraoceanic morphostructural megajunction at the boundary of two lithosphere plates.

СОВРЕМЕННАЯ ДИНАМИКА МОРСКОГО БЕРЕГА КУРШСКОЙ КОСЫ В ГРАНИЦАХ РОССИЙСКОГО СЕКТОРА ЮГО-ВОСТОЧНОЙ БАЛТИКИ
ЖИНДАРЕВ Л.А., ЛЫГИН А.А., МАРУСИН К.В., СВИРИДОВА Е.А., ФЁДОРОВА Е.А., ХАБИДОВ А.Ш. — 2013 г.
The coastal dynamics of the Curonian Spit, a large accretive landform with its eroded root, is discussed. For this area, the new data on the coastal development for the last 100 years were obtained; the characteristic of current coastal state was given; mathematical simulation of the coastal processes for assessment of the sediment defi cit in the near shore zone was made. Evanescence of the sediment deficit phenomenon in the area under study is demonstrated. Here, even during rather short periods of the deficit increase, the development of wave-induced destructive processes is observed; therefore three major ways to mitigate the risk of coastal erosion (i.e. the construction of impenetrable or penetrable groins, a detached breakwater and an artificial beach) are considered, including the peculiarities of the spit shores development as a result of coastal protection activities.

СОРЫ КАК ФОРМЫ АРИДНОГО РЕЛЬЕФА
ПИЩУЛОВ С.А. — 2013 г.
The existing definitions of the terms "sor" and "sor depression" were analyzed. A variety of formulations arises from the lack of the knowledge about genesis of these arid landforms. Multiplicity of their origin leads to the diversity of their morphometric, geochemical, and soil characteristics. The analysis of literature and data obtained during field researches allowed author to suggest general definition of the term "sor": closed depression of various genesis with an ephemeral piece of water, characterized by intensive salinization and formation of solonchaks with strongly pronounced saline horizon.

СТАНОВЛЕНИЕ СОВРЕМЕННЫХ ДОЛИН И ЕГО ЗНАЧЕНИЕ ДЛЯ ГЕОЛОГИИ РОССЫПЕЙ
ПОСТОЛЕНКО Г.А. — 2013 г.
The modern plain and mountain river valleys had the maximum depth at the beginning of Quaternary. Buried alluvium in the valleys occurs at different depth and is in different states of preservation due to Quaternary intra-valley alterations. But placer mineral content is richest in the most ancient alluvium. That is why the quaternary valley history and the state of preservation of buried alluvium play an important role in the heavy mineral placers prospecting.

ФОРМИРОВАНИЕ ДОННЫХ ОСАДКОВ В ПРИБРЕЖНОЙ ЗОНЕ АНГАРСКИХ ВОДОХРАНИЛИЩ
КАРНАУХОВА Г.А., СКОВИТИНА Т.М. — 2013 г.
It is shown that accumulation of sediments and formation of the coastal banks on the Angara reservoirs occur in the areas of predominant abrasion shores. Abrasion produces more than 200 Mt/y of loose sediments, 40% to 90% of which participates in formation of coastal banks occupying only 1% of the reservoirs' area. Granulometric composition, mineralogical and geochemical characteristics of the coastal banks sediments correlate with the abrasion shores rock composition.

ФУНДАМЕНТАЛЬНЫЕ ПРОБЛЕМЫ АНТРОПОГЕННОЙ ГЕОМОРФОЛОГИИ
СИМОНОВ Ю.Г., СИМОНОВА Т.Ю. — 2013 г.
In recent years, interest in applied geomorphological studies aimed at the human-environment interaction decreased. This is largely due to the lack of appreciation of geomorphological knowledge. To overcome this, it is necessary to change the status of applied geomorphological research and create a new line of basic geomorphological studies anthropogenic geomorphology and to define its subject and logical structure. These questions are proposed to geomorphologists for discussion.

ЭВОЛЮЦИЯ ЛАНДШАФТОВ И РЕЛЬЕФА ЦЕНТРАЛЬНОГО МЕКСИКАНСКОГО НАГОРЬЯ В ПОЗДНЕЛЕДНИКОВЬЕ И ГОЛОЦЕНЕ
СЕДОВ С.Н., СОЛЛЕЙРО-РЕБОЛЛЕДО Э., СЫЧЕВА С.А. — 2013 г.
The paper describes the reconstructed history of landscapes and relief of the Central Mexican plateau in the final stage of Late Pleistocene and Holocene. The new stage of erosion has started in LGM with the formation of small lakes and further initiation of barrancos - gullies along the slopes of small and large volcanoes. This stage was not unidirectional, but had several alternating stages with the filling of depressions (small lakes, heads of barrancos, paleocuts) and their stabilization with the formation of heterochronous soils. The highest rates of gullies formation took place at the end of Pleistocene - beginning of Holocene, and at the present time when the badlands are forming. The stages of linear erosion (formation of barrancos) alternated with the increased sheet erosion (accumulation of colluviums in the depressions with further soil or tepetate formation). Soils were associated with the warm and wet enough climatic conditions about 13 350, 8 100, and 6 200 years ВР. Tepetates were formed under cool and wet environment. The role of small lakes was revealed. Small lakes at various levels being periodically broken through gave rise to the barrancos formation or dried out. The anthropogenic erosion had several stages: formation of the eroded sites (heads), barrancos formation inside the filled paleocuts, badlands formation. The "scalped" areas were formed in the sites of the contact of several exposed tepetates of various gullies. Such areas (badlands) may reach considerable size and are practically unsuitable for agricultural use.

Heavy dust storms within the area of eolian morphogenesis in Eurasia and orientation of eolian mineral flows are related to formation of Asian anticyclone and its influence on atmosphere. Its centre is moving from Middle and Lower Volga, Western Kazakhstan to Altai-Sayan Mountains and Northern and Central Mongolia. Formation of cyclonic whirlwinds by its periphery determines the formation of storms, hurricanes and strong blowing dust. These processes are especially strong during early spring (March-April) when contrasts of temperatures are maximal and cyclonic activity is most intensive at the polar front. When center of anticyclone is over Central Mongolia and cyclone is over the Yellow Sea and Korea eolean processes are extremely strong; in such case there happen severe dust storms in the areas of air currents convergence over the eastern Goby, plateau Ordos, and Loess plateau.

ЭРОЗИОННО-РУСЛОВЫЕ СИСТЕМЫ, ИХ СТРУКТУРА, САМОРЕГУЛИРОРОВАНИЕ И ФУНКЦИОНИРОВАНИЕ
ЧАЛОВ Р.С. — 2013 г.
Erosion-channel system (ECS) is defined as a complex of water streams, erosion-accumulation processes acting within basins of different order and resulting landforms. The author showed that all components of ECS have characteristic features in all their members. The functioning and self-regulation of the ECS depend on the processes in the rills, ravine thalwegs, small, middle and large rivers, i.e. formation and development of the ephemeral and perennial watercourse channels have joint base but their morphological effects turn out different. The dependences of channel parameters on their water content, runoff, sediment budget, and transport capacity were established. These dependences lie in the base of the self-regulation of whole ECS and their members.

Abrasion in the eastern Gulf of Finland coastal zone is favored by geological and geomorphologic factors, e.g. weakness of Quaternary deposits, sediment defi cit, bottom and coastal relief. Extreme abrasion events occur as a result of coincidence of long-lasting western or south-western storms, high water level, and absence of stable sea ice during such events. In the last decade extreme erosion events took place during autumn-winter seasons of 2006-07 and 2011-12.

БЕРЕГА И НАГОРНЫЕ БЕРЕГОВЫЕ ОТКОСЫ ОКИ И ВОЛГИ В НИЖЕГОРОДСКОМ ПОВОЛЖЬЕ
ВАРЁНОВ А.Л., МАНАЕВА Н.В., ФРИДМАН Б.И. — 2012 г.
Bank escarpments are a high and steep slopes of river valley. The head-on escarpments are undermined by river, the shadow ones are far from riverbed. All northward escarps of the Privolzhskaya highland facing the Oka and the Volga rivers within Nizhegorodskaya region consist single linear morphostructure with specifi c mass wasting landscapes.
