Shrinking of intermontane basins and expansion their flanking ranges by reverse faulting backthrusting in two counter-dipping systems is a typical mechanism crustal shortening mountain building Central Asia. This realized along the Kurai Fault Zone (southeastern Gorny Altai). Motions on fault maintained thrusting Range Kubadru Uplift Basin sediments caused growth foreberg before front. Forberg separates narrow Aktash from Basin. The paleoearthquakes were generated faults that delineate...
ABSTRACT Palaeoseismology studies the footprints of ancient earthquakes to improve knowledge about modern seismicity territory. A ground‐penetrating radar (GPR), among other geophysical methods, is used for quick determination shallow stratigraphy – displaced, oblique layers within fault zone. GPR data interpretation from diverse and complex reflection patterns zone heavily depends on interpreter's experience. The range different parameters in which this method can be successfully applied...
Zabolotsky peat bog is a unique biospheric and cultural-historical archive located in the north of Moscow Region on territory Dubna River lowland. Despite advances studying region, question reconstruction primitive population habitat remains unresolved. Until recently, it has been be-lieved that Late Valdai period, lowland was covered by waters an extensive glacier-dammed Tver paleolake, drained only at turn Pleistocene Holocene. It assumed lake's existence prevented settlement territory,...
The Gorny Altai is part of the system intracontinental Cenozoic orogens that originated from Eurasia-India collision. There crustal contraction, which followed by numerous earthquakes, and highest concentration earthquake sources observed in south-eastern region. paleoearthquake surface ruptures Kubadru Fault Zone was studied at three representative sites using GPR method conditions weakly consolidated coarse clastic deposits upper section permafrost development.

Ice wedges are an abundant feature of frozen ground and pose a hazard to any infrastructure near them due potential thaw subsidence. Several studies have shown that ground-penetrating radar (GPR) is suitable geophysical tool locate the position these features. Here, we use finite-difference-time-domain (FDTD) modeling gprMax simulate synthetic GPR data across different types ice wedges. Using sets, examine imaging size geometry bodies. We demonstrate for data, it possible perform...
The paleohydrological condition in the Rostov depression (Yaroslavl region) has been subject of many years discussions. ideas about Holocene fluctuations Lake Nero level differ among researchers. We have studied structure bottom sediments and topography deepest northeastern part lake. A bathymetric survey was carried out. Drilling with selection undisturbed columns, GPR profiling, radiocarbon dating a set lithological analyzes were performed. Stratigraphic unconformities indicate drop lake...
Summary Ice wedges are prominent phenomena of permafrost landscapes. These ice bodies typically build a characteristic polygonal micro topography, thus determining indirectly the distribution moisture, vegetation, and elements within seasonally unfrozen active layer. However, existence in subsurface is not always delineable based on surface data. Furthermore, increased potential subsidence poses hazard to any infrastructure nearby case temperature increase. Also, identification hidden...
Summary Ice wedges are prominent phenomena of permafrost landscapes and cause a characteristic polygonal patterned ground. However, the existence ice bodies in subsurface is not always delineable based on surface data. Detection imaging these interest to identify regions increased subsidence potential for scientific field work such as drilling programs. We demonstrate two synthetic datasets increasing complexity, that ground-penetrating radar can be used determine wedge structures image...
Summary This study presents the new data from faults within Upper Pleistocene-Holocene deposits, presented by pebbles, cobbles, and boulders with a coarse-medium sandy matrix. Such sediments produce complex diffuse wave patterns on GPR data, it is challenging to recognise faulting among them. Thus, we solved direct problem of detecting fault zone features using numerical modelling. Comparing simulation results field (GPR profiles trench wall sketches), proposed summary signs profiles.
Многолетнемерзлые породы (ММП) имеют достаточно сложную структуру, связанную с наличием в них различных ледяных образований. В ММП часто встречаются пластовые и жильные льды, а также криопэги – незамерзающие рассолы. Важной задачей, которую необходимо решать при проведении инженерных изысканий других геотехнических работ районах распространения ММП, является контроль состояния приповерхностного сезонно-активного слоя. Это чрезвычайно важной задачей оценке солифлюкционной опасности района....
