Differentiating hyperpycnal, hypopycnal and turbidity current deposits in late Quaternary glaciogenic mud

The Depositional Record, Volume 12, Issue 1, February 2026.
X‐ray CT and microscopic analysis of glaciogenic mud provide insight into the deposits of sediment‐laden density flows and reveal that strata comprise two microtextural motifs. The deposits of bottom‐hugging hyperpycnal flows and slope‐failure‐related turbidity currents are characterised by laterally continuous, sharply bounded silt‐rich and clay‐rich ...

Laguna Fuente de Piedra: An example of a dolomite factory recording ~50,000 years of depositional and paleoclimatic evolution

The Depositional Record, Volume 12, Issue 1, February 2026.
This study characterises carbonate mineral precipitation mechanisms and their paleoenvironmental implications in a semi‐arid, saline playa lake system. SEM image with EDS spectra shows microcrystalline, spherical shaped dolomite crystals from Laguna Fuente de Piedra composed of nanocrystals with bacterial voids and EPS.

Sedimentary records of palaeohydrological variability during the Late Holocene in the Lower Narmada Basin, western India

The Depositional Record, Volume 12, Issue 1, February 2026.
Late Holocene palaeohydrological changes in the lower Narmada Basin, India, revealed using multiproxy analyses of the Orsang River terrace sediments. Distinct depositional phases corresponding to global climatic events were recorded. High‐magnitude floods in the Narmada River during the MWP, and within the tributary Orsang River during DACP and LIA ...

Precipitation mechanism of anhydrite cement in lacustrine tight sandstone: Implications for fluid activity, mass transfer and pore origin of open diagenetic system in tight sandstone

The Depositional Record, Volume 12, Issue 1, February 2026.
This paper discusses a new model concerning the precipitation mechanismand significance of anhydrite cement in tight sandstone. Anhydrite cement ismainly formed by the dissolution and reprecipitation of early‐diageneticcalcite cements, feldspars and volcanic rock fragments at the mesodiageneticstage.
