recommendations! Published in 2017 at "Landslides"

DOI: 10.1007/s10346-017-0890-z

Abstract: Due to the heterogeneity of geological materials, the shear strength of slip zone soils varies randomly. In general, the probability distribution of shear strength is determined empirically or tested by the few numbers of collected… read more here.

Middle Triassic (Anisian-Ladinian) Tejra red beds and Late Triassic (Carnian) carbonate sedimentary records of southern Tunisia, Saharan Platform : Biostratigraphy, sedimentology and implication on regional stratigraphic correlations

DOI: 10.1016/j.marpetgeo.2016.10.019

Abstract: Abstract The “red beds” of the Triassic succession outcropping at Tejra-Medenine (southern Tunisia, Saharan Platform) have yielded rich fossil assemblages of both freshwater and brackish-marine invertebrates and vertebrates. The new discovered fauna indicates an Anisian-Lower… read more here.

DOI: 10.1016/j.palaeo.2020.109967

Abstract: Abstract The continuous existence of the Marinoan Ice Age, a late Cryogenian panglaciation (Snowball Earth), is challenged by the occurrences of widespread glacial marine and nonglacial deposits consisting of stratified diamictite, laminated siltstone and claystone,… read more here.

DOI: 10.1016/j.precamres.2017.12.022

Abstract: Abstract Samples of red bed sediments in several Mesoproterozoic successions contain enrichments of tellurium (Te), including discrete telluride minerals. The tellurides were neoformed during redox-controlled diagenesis, rather than representing mechanical concentrations of heavy minerals. Tellurium… read more here.

DOI: 10.1016/j.sedgeo.2019.105519

Abstract: Abstract Carbonate oceanic red beds (ORBs) are unusual in Phanerozoic shelf settings but can be widespread during discrete intervals. Several scenarios have been invoked to explain the origin of these ORBs but there remains uncertainty… read more here.
