between the lower and upper cretaceous there were some diastrophic movements, belonging to the austrain phase. these movements, which can be traced in many parts of north and central iran, caused extensive precenomanian erosion. even in southwest iran a wide spread discontinuity is reported at the base of the kazhdumi formation, which is possibly related to these movements. in the kopet - dagh ...

The composite Albian–Eocene orogenic wedge of the northern part Inner Western Carpathians (IWC) comprises European Variscan basement with Upper Carboniferous–Triassic cover and Jurassic to Cretaceous sedimentary successions a large oceanic–continental Atlantic (Alpine) Tethys basin system. This paper presents an updated evolutionary model for principal structural units (i.e., Fatricum, Tatricum...

The fossil record for neoceratopsian (horned) dinosaurs in the Lower Cretaceous of North America primarily comprises isolated teeth and postcrania of limited taxonomic resolution, hampering previous efforts to reconstruct the early evolution of this group in North America. An associated cranium and lower jaw from the Cloverly Formation (?middle-late Albian, between 104 and 109 million years old...

The combination of oceanographic processes and a negligible fluvial terrestrial sediment contribution makes the Santos Basin margin (southwestern Brazil) unique environment for studying thew morphological imprint bottom currents on seafloor morphology. We divide into four domains: outer shelf, upper, middle, lower slope, based an analysis sub-bottom Chirp profiles, multichannel seismic data, hy...

Clumped isotopes geothermometry was applied to two dolomitic hydrocarbon reservoirs. Results indicate that late burial dolomitization occurred at ~110°C in the Albian Pinda dolostone (offshore Angola) and ~90°C in the Mano-Meillon dolostone (Aquitaine Basin, France), and did not continue on during subsequent burial/thermal evolution to present-day conditions (150160°C). This study illustrates t...

ABSTRACT Behavior of sediment gravity flows can be influenced by seafloor topography associated with salt structures; this modify the depositional architecture deep-water sedimentary systems. Typically, salt-influenced successions are poorly imaged in seismic reflection data, and exhumed systems rare, hence detailed sedimentology stratigraphic these remains understood. The Triassic (Keuper) Bak...
