Journal: :The depositional record 2023

Abstract Deepwater carbonate deposition is relatively poorly understood but an area of vigorous research in academia and industry, where these deposits are a significant component many unconventional petroleum reservoirs. Recent studies modern deepwater carbonates have highlighted the wide variety depositional processes, sediment types resultant geomorphology; however, well‐documented outcrops ...

Four TOC-rich shale intervals spanning the Frasnian–Famennian (F–F) boundary were recovered in a drillcore (West Valley NX-1) from western New York (USA) and radiometrically dated using Re–Os. Two of the black shale intervals (WVC785 from ∼2.9 m below, and WVC754 from ∼6.4 m above the F–F boundary, respectively) yielded statistically overlapping ages with uncertainties of b1.1%. An interpolated...

The block and basin tectonostratigraphic framework for the northern Pennine (rift) Basin, within which buoyant granite intrusions core intra-basin fault-bounded blocks, has long held traction. However, many of elements this are rooted in primitive tectonic models and, perhaps unsurprisingly, corresponding depositional often reflect this. Using sedimentological sedimentary provenance approaches,...
