Skład frakcjonalny stożków gruzowych w kontekście zróżnicowanego klimatu peryglacjalnych stoków górskich (na przykładzie Spitsbergenu i środkowej Azji) = Grain-Size Composition on Talus Slopes in the context of disparate climatic conditions of periglacial mountain zones (exemplified by Spitsbergen and Central Asia)

Talus slopes origin is connected both with weathering and transport of the rock grain. The formation these landforms an effect many climatological, morphological geological factors. grain size surface talus slope brings some information about way deposition mechanisms. main aim paper to present different in two mountain locations - arctic periglacial semi-arid continental climate zones. Results from study sites are presented. first one was located on Spitsbergen Island, its SW coast, near Polish Polar Station. periglacial, average annual temperature -3,2°C, precipitation 494,6 mm. exposed west, face built gneiss, crystalline shales marbles intrusions. There permafrost as well active layer noted this site. second site Fann Mountains, part Pamiro-Alay massive Tajikistan. 1-2°C (meteo stations nearby: 6,6°C Iskanderkul 2204 m.a.s.l., 0,7°C Shahristan Pass 3143 m.a.s.l.), 300 Slope south, material a Devonian limestone. No observed area. On sites, similar methods were used. Profiles four measuring points designated. points, 0,5 x m square marked perpendicular photographs 1,5 distance made. Grain sizes analyzed BaseGRAIN software. In Asian high-mountain conditions lack low causes, that there no factor water. Domination gravitational processes sorting when heaviest fragments transported longer deposited lower positions slope.
