Cover Story: The Hell Creek Formation of North America is one of the few terrestrial units which preserve the K–Pg boundary. It is famous for its dinosaur fossils, such as Triceratops and Tyrannosaurus, which disappear at the K–Pg boundary mass extinction at the upper formational contact. This paper reviews the stratigraphy of the Hell Creek and implements a sequence stratigraphic framework to aid in regional correlations. Revisions suggest that the Hell Creek Formation probably represents ~700 k. y. of deposition. This image shows the basal formational contacts and depositional sequence boundaries in a typical section exposed near Fort Peck Lake, Montana. View this paper

Permafrost thawing leads to mobilization of the vast carbon pool into modern biogeochemical cycling through the enhanced release of dissolved organic matter (DOM) and production of greenhouse gases (CO2 and CH4). In this work, we focus on the study o...

Fluvial sediments are valuable paleoenvironmental archives of the Quaternary. Since besides environmental factors they are also affected by local tectonics or intrinsic processes, large instead of small catchments should be studied. In drylands cover...
