The major arguments in favour of unconformities being classified as periglacial features are: undisturbed and well stratified gravels in the lower portion of the outcrops, periglacial involutions surrounded by stones, those on the periphery
in the centre portion being almost in a vertical position, with sediments partly of Holocene age lacking unconformities in the upper portion.
Studies of the topography modelled by the Moscow ice sheet reveal ed its primary features being rather well preserved. Its morphological and morphometric parameters distinctly differ from those of older (Dnieper) and younger (Valdai) ice ages.
The low terrace of the Seine in the meander of Elbeuf presents three periglacial alluvial deposits and interglacial estuarine formations intercalated, the whole sequence being dated from Saalian. The fauna of great mammals is well represented: among
Slope rock glaciers consist of coarse debris and ice, the cryogenous structure being of basic type. The structure, spatial distribution, formation and evolution of the rock glaciers depend on climatic and geocryological conditions, rocks lithology
, slope angle and profile, as well as on the slope processes rate. The slope rock glaciers formation and evolution are conditioned by an action of a number of cryogenic processes and by plastic-viscous characteristics of the rock glaciers material. - (L'Ed.).
The fault scarps in the vicinity of Delphi (Greece) are far from being completely graded| they were maintained by recurrent faulting up to recent Quaternary. Though both originated mainly from seismoclastic breaking up and subsequent mass movements
which interfered with tectonic activity. The scarcity of Rissian deposits is questioned from the morphoclimatic point of view and the seismic one as well.
sediments. The process of incoalition as well as sandstone and mudstone diagenesis can be reconstructed by means of the settling. For the time being the incoalating gases dispersed and were bound down at the end of the settling. Only young fracture
understanding of urban and rural problems requires an overview of the dynamics of economic and social change that affect individual well-being in both environments.
The zonality of heat, water, air and salt regimes in the loessy hilly land of Trnava, being described, has proved that mountain-adjacent soil zonality came into being prevailingly owing to the climatic factor conditioned by geomorphology
Results of the drilling of three new wells along the Belgian coast, till the Caledonian basement of the Brabant Massif. All three wells Den Haan (22W/276), Knokke (11E/138) and Oostduinkerke (35E/142) had a classical well log program (resistivity
, spontaneous potential, natural radioactivity and caliper)| additionally in the Knokke well density and acoustic transit time measurements were done.
Az alfoldi rétegvizes kutak gaz-elofordulasi rendszerének foldrajzi vizsgalata. (Geographical analysis of the occurrence of natural gas in artesian wells on the Great Hungarian Plain)
In the artesian wells of the Danubian Basin often free and dissolved gas comes to the surface causing a lot of problems. This research work has found that the areas with wells containing gas do not coincide with areas rich in carbo-hydrates or do
Les puits naturels du Tournaisis. Etude de leur localisation et contribution à l'étude de leur genèse. (The natural wells in the Tournaisis: study of their location and contribution to the study of their genesis)
About 100 natural wells or sink-holes (93 from 1955 to 1983) are known in the Tournais area. They are due to deep karst dissolution. Areas favourable to natural wells include the infiltration area of the Carboniferous Limestone groundwater
at the most favourable points like boundaries of this infiltration area and flood plains, and also the lowest level area of the Carboniferous Limestone groundwater which created local caves that can easily collapse. Well formation also depends on weather. (LW).
in recent tectonics character. The Gissarskaya zone coincides with the Foremost zone of the South Tien Shan, the Petrovskaya one with the Outer Pamir-Kunlun zone, their boundary being at the Vakhsh upthrust line. Recent structures evolution in inherited from
Late and Middle Pleistocene orogenous structures. The whole area of the Garm polygon rises now, the rates of the recent rise being lower at the Foremost zone of the South Tien Shan as compared with Outer Pamir-Kunlun zone.
Optimum well sampling distance of groundwater levels in till and coversands, Leerinkbeek Catchment Area, The Netherlands
, the optimum well sampling distance of groundwater levels in till and coversands is 855 m, whereas the average distance in the national groundwater netword (12,000wells) is 1600 m. The distance of 855 m corresponds to half the average distance between soil
classes, mapped on the 1: 25,000 soil maps. The design of an optimum groundwater well network will thus benefit from 1: 25,000/1: 50,000 soil maps and land use maps.
