Introduction and background: High Resolution Imaging Science Experiment (HiRISE) images with resolutions of ~25-32 cm/pixel [1] enable to analyze putative periglacial landforms on Mars (e.g., polygons, scalloped depressions) in very high spatial resolution. However, the investigation of terrestrial analogues is necessary to improve the understanding of possible ground ice degradation processes ...

Problems of the research. The article considers origin, morphology and dynamics unique forms coastal-marine relief in coastal zone non-tidal seas, under influence hydrogen factor, an exceptionally strong potential mechanical energy, sufficiently large reserves sand deposits (fractions 0.05–1.00 mm), active wave impulses currents energy dissipation, nanoexchange between shore underwater slope. I...

Large-scale patterns evident from satellite images of aeolian landforms on Earth and other planets; those of intermediate scale in marine and terrestrial sand ripples and sediment profiles; and small-scale patterns such as lamellae in the bones of vertebrates and annuli in fish scales are each represented by layers of different thicknesses and lengths. Layered patterns are important because the...

1961年に東京都昭島市，JR 八高線の鉄橋の下の多摩川河床で，アキシマクジラ（Eschrichtius akishimaensis）の化石が発見された．化石は上総層群小宮層（平山層に相当）から産出したもので，前期更新世に少なくとも2つの系統のコククジラ属が生き残っていたことを示唆するという．産出地点の下流に目を向けると，河流に平行する高さ2 m程度の島状の地形が多数発達している．島と島の間の溝は，下流に向かって細長く続く．水位が上昇すれば，島々がまるで牛の群れが泳いでいるように見えることから，小泉（1996）はこれを「牛群地形」と呼んだ．多摩川では，明治時代頃から1968年まで，河床の砂利が盛んに採取された．青梅市から狛江市の間では，採掘箇所は104か所（1963年度末）にも及んだらしい．砂利の採取が引き金となって，おもに半固結の砂層からなる小宮層が露出し，徐々に水流が縦溝を刻み，...
