Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

open access: yesSedimentology, EarlyView.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

Sedimentology of silica granules and haematite in the 3.47 Ga Antarctic Creek Member, Mount Ada Basalt, Western Australia

open access: yesSedimentology, EarlyView.
ABSTRACT The Paleoarchean Antarctic Creek Member of the Mount Ada Basalt, Eastern Pilbara Terrane, Western Australia, includes beds of jasper and white chert composed of sand‐sized silica granules that often contain or are mixed with silt‐sized particles of haematite.

Supercritical‐flow structures in a Cretaceous submarine channel–lobe transition zone, Point Loma Formation, California

open access: yesThe Depositional Record, Volume 12, Issue 3, June 2026.
We document meter‐scale antidune and cyclic‐step deposits in channel–lobe transition zone (CLTZ) deposits of the Upper Cretaceous Point Loma Formation in San Diego, California. These results provide new insights into sediment transport dynamics in CLTZ environments, which are critical for understanding reservoir connectivity and heterogeneity in ...
