The 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.

A non-classical view on calcium oxalate precipitation and the role of citrate
Nature Communications, 2017 The formation mechanism of abundant calcium oxalate biomaterials is unresolved. Here the authors show the early stages of calcium oxalate formation in pure and citrate-bearing solutions by using a titration set-up in conjunction with solution quenching ...

The 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.

A Log‐Ratio‐Based Algorithm for Petrologic Mass‐Balance Problems and Uncertainty Assessment
Geochemistry, Geophysics, Geosystems, 2023 We provide a new algorithm for mass‐balance calculations in petrology and geochemistry based on the log‐ratio approach championed initially by John Aitchison (e.g., Aitchison, 1982, https://doi.org/10.1111/j.2517-6161.1982.tb01195.x; Aitchison, 1984 ...
