Geoscientists employed current-day stratigraphic, depositional and paleontological models, along with modern technological muscle to provide updated insights of the Cambrian period of the Grand Canyon ...
Bands of soft rock such as clay and sand are weaker and therefore they can be eroded quickly. This process forms bays. A bay is an inlet of the sea where the land curves inwards, usually with a ...
Chemical sediments provide a key geobiological record – preserving a physical record of fossil life forms and depositional environments and a geochemical record of seawater and pore fluid chemistry. I ...
I approach these studies with a focus on the structure, distribution, and stable isotopic composition of cell membrane lipids (biomarkers) that are preserved in modern and ancient depositional systems ...
The morphology of blowouts is characterised by a deflation (erosional) basin floor or depression, lateral erosional walls, and a downwind depositional lobe (Figures 2 and 3, photo 6). The sand ...
"Modern" refers to deposits whose geometry and surface morphology reflect original depositional conditions, usually on the seafloor or in the shallow subsurface (Mutti & Normark 1991). "Ancient ...
