Additionally, landslides represent major natural hazards (Petley, 2012) and efficient geomorphological processes that contribute to global sediment flux from land to the sea (Korup, 2012).Although traditionally reported from mountain areas (Korup et al., 2007) and …

A combination of remote sensing, lithological analyses and luminescence dating is used to interpret the complex aggradation history of the Quaternary alluvial ...Quaternary alluvium and alluvial terraces compose an aquifer of major importance along the North Fork Red River from Beckham County, Okla. at the border of the Texas Panhandle to its junction with the Red River and along the Red River eastward to Jefferson County, Okla. Alluvium and alluvial terraces are covered by dune sands in most of the area. The Quaternary alluvium is composed mainly of gravel, sand, clay and silt of diverse origins. At the bottom level of the Quaternary alluvium, the bedrock consists of the Pliocene-aged limestone and marl (DSI 1987). Fig. 2 (modified after DSI 1987)Question: Please help When excavating a field of Quaternary alluvium (modern sediments), a layer of limestone bedrock is encountered. The limestone is found to have been intruded by an igneous dike. Both the limestone and the dike are fractured by a fault.
