Whitings in the Red Sea

open access: yesThe Depositional Record, EarlyView.
We present the first documentation of whitings in the Red Sea, observed in a lagoonal environment. These events are linked to cascading offshore dense waters that liberate trapped sea floor nutrients, triggering algal blooms and elevating alkalinity, which is buffered by direct CaCO3 precipitation—contributing to the accumulation of aragonite mud in ...

Orbital and eustatic control of basin hydrology during the first stage of the Messinian Salinity Crisis

open access: yesThe Depositional Record, EarlyView.
The paleo‐hydrology of the Sorbas Basin (SE Spain) and the wider Mediterranean region during the deposition of the Primary Lower Gypsum (PLG) stage of the Messinian Salinity Crisis, from ~5.97 to ~5.60 Ma, was affected by tectonics, precession‐forced climate oscillations, and eustatic sea‐level change.

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

open access: yesThe Depositional Record, EarlyView.
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 ...

Microscopic time‐dependent mechanical behavior of shale derived from nanoindentation

open access: yesDeep Underground Science and Engineering, EarlyView.
This study conducted grid nanoindentation creep tests to systematically analyze the microscopic creep behaviors of shale. Based on the analysis of creep strain rate sensitivity, the primary mechanism of microscopic creep in shale was found to be the extension and closure of microcracks.
