Siliceous sponges or seawater as a silicon source? Tracing silicon burial pathways of the Upper Cretaceous opal‐CT deposits using δ30Si and δ7Li

open access: yesSedimentology, EarlyView.
ABSTRACT Classical models of formation of sedimentary siliceous rocks (flint, chert, opoka) commonly assume that the Cretaceous marine silicon (Si) cycle was primarily biologically controlled, broadly analogous to the modern ocean. In this framework, siliceous sponges are regarded as the principal source of dissolved silica (dSi) to sediment porewaters,

Quantification of dryland depositional environments across contrasting fluvio‐aeolian and fluvio‐lacustrine transects: An integrated subsurface and outcrop analogue study of the Organ Rock Formation, Utah, USA

open access: yesSedimentology, EarlyView.
ABSTRACT The standard subdivision of a distributive fluvial system (DFS) into proximal, medial and distal zones is typically based on the proportion of channel bodies and/or the degree of channel amalgamation, reflecting a downstream fining trend towards a mud‐prone terminal pinch‐out.

Gravel and sand barrier preservation at geological (Cenozoic) timescales: Insights from the southern Namibia continental shelf

open access: yesSedimentology, EarlyView.
ABSTRACT An apparent disconnect exists between the morphology and behaviour of modern coastal barriers and barrier‐associated sediments preserved in the geological record, reflecting modification and selective preservation over geological timescales.

Production of Shale Oil

open access: yes, 1982
Intensive pre-project feasibility and engineering studies begun in 1979 have produced an outline plan for development of a major project for production of shale oil from private lands in the Piceance Basin in western Colorado.

Salt Range Formation of Pakistan Preserves Unique Record of Volcanic Fertilization During the Ediacaran Shuram Excursion

open access: yesTerra Nova, EarlyView.
ABSTRACT Thin, discontinuous, organic‐rich oil shale beds in the siliciclastic‐evaporitic Salt Range Formation (SRF) of Pakistan are of approximate Neoproterozoic to Cambrian age based on stratigraphic constraints. The beds are enriched (26–43 wt.% total organic carbon, TOC) in aliphatic organic matter (OM) of low thermal maturity despite their ...
