27 Supercritical flow phenomena are fairly common in modern sedimentary environments, yet their 28 recognition and analysis remain difficult in the stratigraphic record. This fact is commonly 29 ascribed to the poor preservation potential of deposits from high-energy supercritical flows. 30 However, the number of flume datasets on supercritical flow dynamics and sedimentary 31 structures is ver...

We develop a recycling model using 13C/12C mass balance for net growth/loss of the sedimentary organic carbon (Corg) reservoir, and apply it to the Neogene bulk marine carbonate δ13C record. The model allows for variations in photosynthetic fractionation factors, carbon cycling rates, and the isotopic composition of riverine carbon inputs to the oceans. The sign of the net flux term is controll...

[1] The southern Canadian foreland fold-and-thrust belt (FFTB) (SW Alberta–SE British Columbia) records the interplay between foreland basin evolution with the deformingwedge and thus controls the regionalscale overburden and exhumation history. Overburden estimates are typically based on the assumption that peak burials were reached by sedimentary burial prior to the emplacement of thrust shee...

Erosional and sedimentary features associated with flooding have been documented in both modern and past cases. However, only a few studies have demonstrated the relationship between these features and the corresponding hydraulic conditions that produced them, making it difficult to evaluate the magnitude of paleo-flooding. This study describes the characteristics associated with inundation dep...

Volcanogenic massive sulphide (VMS) deposits are also known as volcanic-associated, volcanic-hosted, and volcano-sedimentary-hosted massive sulphide deposits. They typically occur as lenses of polymetallic massive sulphide that form at or near the seafloor in submarine volcanic environments. They form from metal-enriched fluids associated with seafloor hydrothermal convection. Their immediate h...

Climate is an important environmental parameter of the early Earth, likely to have affected the origin and evolution of life, the composition and mineralogy of sedimentary rocks, and stable isotope ratios in sedimentary minerals. There is little observational evidence constraining Precambrian climates. Most of our knowledge is at present theoretical. Factors that must have affected the clima...

The origin and life cycle of ocean islands have been debated since the early days of Geology. In the case of the Canary archipelago, its proximity to the Atlas orogen led to initial fracture-controlled models for island genesis, while later workers cited a Miocene-Quaternary east-west age-progression to support an underlying mantle-plume. The recent discovery of submarine Cretaceous volcanic ro...

Gran Dolina is a cavity infilled by at least 25 m of Pleistocene sediments. This sequence contains the TD6 stratigraphic unit, whose records include around 170 hominin bones that have allowed the definition of a new species, Homo antecessor. This fossil accumulation was studied as a single assemblage and interpreted as a succession of several human home bases. We propose a complete stratigraphi...

Changes in the stream flow contribute to transformation of river channel due erosion and accumulation. Channel bars move as a result water flow. This article presents results studies carried out on two formed River Vistula that were transformed during emergency discharges from Włocławek reservoir. In order present changes structure texture, pits dug samples taken for grain-size analysis. The ra...

The coastal region of Chabahar Gulf with 1113.7km2 area has been located in the southeast of Iran. In this research, satellite images of ETM+ (2004) were used in order to zoning of sedimentary environments in this Gulf. Methodology of this research was baesd on synthesis of supervised and unsupervised classifications in GIS and ENVI softwares. Based on studies and calculat...
