The Dongying Depression (Bohai Bay Basin, eastern China) was widely filled with evaporite (anhydrite and halite) layers during the Paleogene period, especially middle of fourth member Shahejie Formation (Es4). Most are interbedded mudstone strata. strata Es4 divided into three sections, referred to as upper layers, lower respectively. analysis elemental concentrations, ratios, Pr/Ph suggests th...

Abstract This study investigated the relative distribution of sand-separating minerals and effect sedimentary climatic conditions on their in some soils from northern southern Iraq. The samples were collected four Iraqi governorates: Erbil (included areas Shaqlawa, Soran, Juman), Sulaymaniyah Dokan, Sayed Sadeq, Halabja), Maysan Al-Kahla, Ali Al-Sharqi, Awasha, Kumit, Al-Gharbi, Al-Tayyib), Was...

In this study, the ion concentrations (K+, Na+, Ca2+, Mg2+, Cl?, SO42?, Br?, NO3?, and B3+) boron isotope compositions (?11B) of 34 halite brines samples from Neoproterozoic Salt Range Formation, Punjab, Pakistan were studied. Relation among B3+ vs. ?11B B3+, vs K+ observed, they indicated that these elements originate multiple sources end members identified as seawater, B desorption clays, met...

We present several structural transects throughout the internal part of Tunisian Tell focusing on some representative structures and domains. used also an interpreted seismic cross-section a 3-D view to highlight styles within Tellian units in Fernana-Adissa allochthon domain. The style is mainly represented by active roof-thrust duplex affecting Mesozoic-Cenozoic sequences belonging respective...

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. Foreland fold-and-thrust belts (FTBs) record long-lived tectono-sedimentary activity, from passive margin sedimentation, flexuring, and further evolution into wedge accretion ahead of an advancing orogen. Therefore, dating fault activity is fundamental for plate movement reconstruction, resource exploration, earthquake hazard assessment. Here, we report U–Pb ages syn-tectonic calcite ...

Over the entire Alps, ~75% of ‘catastrophic’ mass-wastings (CMW; rockslides and rock avalanches >105 m3 in volume) still are undated. We have studied radiocarbon-dated a avalanche deposit (RAD) that was not investigated any detail before. The RAD is located near village Münster Inn valley, seismogenically active belt decorated with CMWs pre- to post-Glacial age. detached from succession Triassi...

Field analogues illustrating the early stage of deformation shortening structures in salt-bearing orogenic fold-and-thrust belts are not yet well illustrated literature. The relatively young Messinian salt Algerian basin could represent a good case example such systems. Basin is deep-water Miocene back-arc including layer mobile evaporites up to 2 km thick. was deposited an already inverted bas...
