Mid‐infrared spectroscopy applied to a multi‐level cave system (Montmaurin, SW France): An innovative method for assessing sediment provenance

Sedimentology, Volume 73, Issue 5, Page 1722-1749, August 2026.
ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...

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

Sedimentology, Volume 73, Issue 5, Page 1750-1798, August 2026.
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

Sedimentology, Volume 73, Issue 5, Page 1842-1866, August 2026.
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.

Source‐to‐sink sediment transport reversals during glacial sea‐level lowstands sustain soil formation on pericoastal carbonate terrains

Sedimentology, Volume 73, Issue 5, Page 1892-1910, August 2026.
ABSTRACT Understanding the processes that drive soil formation is crucial for developing sustainable land‐use strategies, as changing land‐use practices and climate change exacerbate soil erosion. The formation of substantial arable soils on carbonate bedrock requires substantial dust accretion as the underlying bedrock lacks siliciclastic material. In

Evolution Model for the Paleoproterozoic Talvivaara Mudstone‐Hosted Ni‐Zn‐Cu‐Co Deposit in Fennoscandia

Terra Nova, Volume 38, Issue 4, Page 221-232, August 2026.
ABSTRACT The Paleoproterozoic Talvivaara mudstone is a very large sulfidic Ni‐Co deposit that records enhanced organic matter accumulation during the global Shunga Event. Here, rock geochemistry and microscale S and Fe isotope composition of in situ pyrrhotites and pyrites are studied in well‐characterised, well‐preserved drill core samples.
