Kumbira forest is a discrete patch of moist forest of Guineo-Congolian biome in Western Angola central scarp and runs through Cuanza Norte and Cuanza Sul province. The project aimed to document the floristic diversity of the Angolan escarpment, a combination of general walk-over survey, plant specimen collection and sight observation was used to aid the characterization of the vegetation. Over ...

Abstract Dissolution of karst rocks (evaporites and carbonates) can cause significant mechanical weakening, but its preparatory role for landslide development has been scarcely explored. Fluvial valleys carved in gypsum bedrock typically display prominent escarpments with numerous landslides perched indicative rapid retreat rate. The stratigraphic cartographic analysis the 37-km-long Remolinos ...

Abstract Despite significant progress in understanding the stability of rock slopes, little is known about time scales evolution slow-moving rockslides. The Ledové sluje rockslide Thaya River canyon a unique and infrequent slope failure developed crystalline rocks Variscan orogen Central Europe. Fresh topography with trenches, walls, slided blocks, scree slopes crevice-type caves has attracted ...

The ruins of the Medieval castle and village El Castellar are located on an abrupt 1.2-km-long scarp Miocene gypsums, in central sector Ebro depression. remains main perched a 100 m cliff River. Considering historical geoarchaeological relevance settlement, this investigation aimed to study geomorphological paleoenvironmental context site during after settlement its later evolution, including c...

An approach to initial assessment of prospective needs for conservation of hill zones and scarps is formulated. The approach begins with a digital elevation model (DEM) and elevation contours generated from the DEM. Three types of hill/slope features are recognized for interactive extraction via geographic information system (GIS). The three types of features are regional ridges, dissected dome...

The NNW-trending Dena Fault, with 140 km length, cuts the major structures of Zagros Fold-Thrust Belt in Borujen region. The fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. This study presents a new interpretation for the kinematics of Dena Fault based on field evidence....

The case for a glacial origin for the upper Proterozoic Kingston Peak Formation is weak. Stratigraphic correlations and rock descriptions suggest a marine depositional environment for the entire formation. The Lower Sandstone Unit of the Kingston Peak Formation is best interpreted as an Antediluvian inner shelf deposit. It is underlain by other widespread shelf deposits, the Beck Spring Dolomit...

The cosmogenic nuclide exposure history method is undergoing major developments in analytical, theoretical, and applied areas. The capability to routinely measure low concentrations of stable and radioactive cosmogenic nuclides has led to new methods for addressing long-standing geologic questions and has provided insights into rates and styles of sur"cial processes. The di!erent physical and c...
