Советская геоморфология - к 60-летию образования СССР

Статья комментирует разработанную авторами генетическую классификацию ледникового рельефа покровных оледенений и ее место в общей генетической классификации рельефа, созданного различными видами природных льдов (криогенеза). Полная многоступенчатая классификация создана впервые.

Рассмотрены эрозионные процессы на территории Нечерноземной зоны РСФСР, развивающиеся в трех основных звеньях гидросети - склоновых потоках, овражно-балочной сети и реках. Выявлены основные количественные зависимости, характеризующие процессы, позволившие составить карты интенсивности смыва почв, густоты овражной сети и скорости смещения речных берегов. Выявляется зональность эрозионных процессов, неодинаковая в различных звеньях гидрографической сети, интенсивность смыва почв и овраг образования нарастает в направлении с севера на юг, а интенсивность деформации речных берегов увеличивается в обратном направлении.

Значение новейших тектонических движений в развитии современного рельефа Земли - сокращенный текст доклада на Всесоюзном совещании «Проблемы неотектоники и современной динамики литосферы›› 27 апреля 1982 г. в Таллине.

Comparison of geomorphological and geophysical data proved both small–local–and large–linear and areal–morphostructures to reflect not only neotectonic structures but some tectonic features due to basement's differentiation into blocks and intense salt tectogenesis. Distribution of small morphostructures differing in degree of neotectonie activity appeared to be controlled by large regional morphostructures: active small morphostructures are mostly restricted to most evelated large ones.

Investigation of wave destruction of the Azov Sea coastal scarps permitted to conclude that on loamy coasts the process results in a very complicated coastal system which differs considerably from one created by abrasion. To use different terms for those processes is important from both theoretical and practical points of view. Some cyclic features are shown in the wave destruction of the Azov Sea coasts. Observation data on the coasts destruction are summarized.

A series of paleogeomorphological environments (including a large paleo-delta of the bird-foot type) has been identified in Western Orenburg region on the basis of the Visean topography reconstruction, the environments were favourable to layers-collectors formation and non-anticlinal oil and gas traps.

Morphostructural analysis applied to the Alps region allowed to trace block structures of the loop-like bend of the Alps. The bend proceeds successively along morphostructural lineaments' zones of the second order. Comparison with geophysical data revealed differences in deep structures of the outlined megablocks, which indirectly indicates the lineaments being deep-seated. The third order lineaments position is in good agreement with basement structures.

A technique of mean slope angle graphs construction is described using contour lines length and steps area measurement at maps. The graphs reveal the presence of topographic steps and their altitude. Two graphs were constructed for two sites at Middle Timan, one being interpreted as single planation surface deformed by inequal tectonic uplift, the other as several steps formed originally at different altitude.

Comparison of height of main mountain structures in Mongolia considering their geology revealed an interrelation between the mountains height on one hand and the intensity and time of general grant formation on the other. Highest mountains are characterised with widespread ancient (Early and Middle Paleozoic) granitoid intrusions and maximum thickness (within the limits of Mongolia) of the earthcrust and granitmetamorphic layer.

Statistical analysis of the surface absolute height and dissection depth and density together with thickness of Quaternary deposits, clay percentage and till content as well as bedrock topography revealed distinct features of recent topography inherited from the bedrock topography. Glacial control over landforms formation is clearly manifested while structural and tectonic factors influence only indirectly through glacial erosion and sedimentation. Heterogeneous character of ancient ice sheets dynamics is proved to manifest itself in general topographic appearance of the area and in deposits composition.
