Diagenetic processes controlled by volcanic detritus of the Lower‐Middle Permian Shanxi and Shihezi sandstone formations, North Ordos Basin, China

open access: yesThe Depositional Record, EarlyView.
Comparisons of Lower‐Middle Permian Shanxi and Lower Shihezi formations from the North Ordos Basin reveal that different types and percentages of volcanic detritus induced by active magmatic cycles can significantly change diagenetic evolution and favourable reservoirs.

A continuous 500‐year sediment record of inundation by local and distant tsunamis in South‐Central Chile (40.1°S)

open access: yesThe Depositional Record, EarlyView.
Tsunami events over the past 500 years inundated Laguna Gemela West (Chile), leading to distinct sandy deposits in the lake record. This provides a complete perspective on tsunami inundation, including giant tsunamis, small local tsunamis and tsunamis that originated >100 km away from the site.

Sedimentary facies and architecture of mixed bioclastic‐siliciclastic deposits forming in an inferred strait environment: An example from the Early Pleistocene of Calabria, southern Italy

open access: yesThe Depositional Record, EarlyView.
Early Pleistocene mixed arenites and their associated conglomerates and sandstones were studied in detail in Calabria, southern Italy. This study suggests that the studied palaeo‐strait was not necessarily a wider and similarly oriented expression of the modern Strait of Messina.

The Cenomanian–Turonian boundary interval in the Western Canada Foreland Basin: Stratigraphy, geochemistry, geochronology and sea‐level changes recorded in expanded and condensed clastic successions

open access: yesThe Depositional Record, EarlyView.
Shallow‐marine mudstone of the Cretaceous Kaskapau Formation in the British Columbia foredeep preserves a 185 m thick record of OAE2. The organic carbon‐isotope and osmium‐isotope excursions can be correlated in detail with other Cenomanian–Turonian boundary sections around the world.

Growth and form of the mound in Gale Crater, Mars: Slope wind enhanced erosion and transport [PDF]

open access: yes, 2013
Ancient sediments provide archives of climate and habitability on Mars. Gale Crater, the landing site for the Mars Science Laboratory (MSL), hosts a 5-km-high sedimentary mound (Mount Sharp/Aeolis Mons). Hypotheses for mound formation include evaporitic,
