This work focuses on the transport processes, sedimentology and clast fabric of slope deposits cropping out in active depositional environments, widespread between 900 and 1000 m in altitude, close to Mormanno, in Northen Calabria. - (NF)
Sedimentology, provenance and biostratigraphy of the Upper Oligocene-Lower Miocene terigenous deposits of the internal dorsale calcaire (Rif, Morocco) : palaeogeographic and geodynamic implication
The AA. present the initial results of sedimentological and chronological studies at Clay Castles : 3 lithofacies associations. A chronology has been established using Optically Stimulated Luminescence : the results indicate formation between 44

Macro- and micro-scale sedimentological analyses of recently deposited tills and complex push/squeeze moraines on the forelands of Icelandic glaciers and in a stacked till sequence at the former Younger Dryas margin of the Loch Lomond glacier lobe
in Scotland are used to assess the depositional processes involved in glacier submarginal emplacement of sediment. The AA. employed clast fabric analyses, micro-morphology, sedimentological logging and structural logging in order to combine micro-scale

The AA. mapped and characterized the sedimentary units overlying the Miocene deposits of the Solimoes and Barreiras formations with basis on an integrated study combining analysis of radar images, field and laboratory sedimentologic data, and C 14

This paper presents a sedimentological, palynological, and phytolith record from a 13 m deep Holocene sedimentary sequence, located in the Tsoaing River valley, southwestern Lesotho. Phytolith and pollen in the terminal Pleistocene layers confirm
The reasons for the initiation of many landforms can in many instances be traced to various magmatic, thermal, tectonic, and sedimentological events, some of which took place in distant geological time. Many landforms are in reality multistage
