Late Jurassic and Early Cretaceous sandstones form major exploration targets across the North Atlantic Margin basins of Eastern Canada and South-West Ireland. Although there have been world-class discoveries offshore Newfoundland in the Late Jurassic Jeanne d’Arc Formation and Lower Cretaceous Hibernia and Ben Nevis Formations, large tracts of the margin remain relatively under-explored, so the...

The Yukon-Tanana terrane in Yukon, Canada, records Late Devonian (ca. 366–360 Ma) rifting and the onset of latest Devonian–Carboniferous arc back-arc magmatism 360–325 Northern Cordillera. Detrital zircon U-Pb Hf isotope analyses indicate that metasedimentary basement was sourced northwestern Laurentia. Sandstones successions generally have robust Devonian–Mississippian age peaks, their signatu...

Igneous intrusions are common in sedimentary basins, and their occurrence can significantly affect the diagenesis reservoir quality evolution of sandstones, thereby strongly impacting hydrocarbons-, geothermal-, CO 2 -storage potentials. The Qasim sandstones Tabuk region (NW Saudi Arabia) experienced shallow burial (<2 km) when Tertiary magma intruded to form basaltic sills (0.4–4 m thic...

Nutrient enrichment of detritus-based streams increases detrital resource quality for consumers and stimulates breakdown rates of particulate organic carbon (C). The relative importance of dissolved inorganic nitrogen (N) vs. phosphorus (P) for detrital quality and their effects on microbial- vs. detritivore-mediated detrital breakdown are poorly understood. We tested effects of experimental N ...

Jones and Crowe (1) raise issues already addressed in our article (2) based on an inaccurate grasp of the literature and several logical misconceptions. The authors suggest that inputs we chose in our kinetic calculations are unsuitable because we used values only from the Black Sea. As described, we made an extremely conservative estimate because the Black Sea is the most rapid Mn-oxidizing en...
