Javoří hory Mountains is a part of Intra Sudetic Basin that belongs to the Permian-Carboniferous section of the Bohemian Massif, whose geological evolution was strongly influenced by volcanic activity. In the Pleistocene epoch cryogenic processes modeled the mountains significantly (frost cliffs, gelifluction streams), which resulted, in connection to the slope orientations, in substantial moun...

The present research focuses on a detailed facies description and interpretation of five alluvial fans of the Qazvin Plain. Beside the tectonic activity that leads to the localization of the fans on the northern margin of the Qazvin Plain, the climate has a significant role in the occurrence of their facies. The alluvial fans are divided into three facies groups: group 1, group 2, and group 3. ...

study area is located in west of iran with relatively rough topography. lithologic units in the region belong from jurassic and cretaccous till recent era. the study area of the alvand mountain region is related to the tectonic zone of the sanandaj-sirjan region and the area dominant neo-tectonic regime appears to be compressional-extensional type. one of the identification tools to find out th...

In erosion and sedimentation problems, estimating the range of significant stream flows to include when computing sediment transport can prove challenging in ungauged or under-gauged basins. This paper describes an event-based model incorporating a geomorphologic instantaneous unit hydrograph and stochastic descriptions of peak flows and frequency of storm events from nearby reference watershed...

Large tropical mountain glacier (TMG) deposits on the northwest flanks of the Tharsis Montes and Olympus Mons volcanoes are interpreted to be the record of ancient climates characteristic of Mars several hundred million years ago when planetary spin-axis obliquity was 451. During this era, polar volatiles (predominantly H2O) were mobilized and transferred equatorward, undergoing adiabatic cooli...

The eastern part of the Adelaide Geosyncline contains well preserved glaciomarine sequences of the Sturtian glaciation (:750–700 Ma) including calcareous or dolomitic siltstone, manganiferous siltstone, dolostone and diamictite units and the associated Braemar ironstone facies. The ironstone facies occurs as matrix to diamictites and as massive to laminated ironstones and comprises abundant Fe ...

Aghajari Formation, known as Upper Fars Group, is developed throughout the Folded Zagros Zone and has a thickness of 2966 m in its type section in SW of Iran and 1473 m in the study area, located 20 km west of Shiraz. Aghajari Formation, in this area, consists of three major facies associations. These are "fine", "medium" and "coarse" grained terrigenous sediments, usually interpreted as channe...
