The Depositional Record, EarlyView.The data and interpretations of this study are used to test the proposal by Goldhammer et al. that a ‘stratigraphy of early diagenesis’ is operational in carbonate depositional systems. What this means is that distinct mineralogical and geochemical changes to rock and sediment occur associated with external controls, such as the rise and fall of sea ...

The Depositional Record, EarlyView.Five large Alpine cave systems on the Dachstein (Austria) were investigated and 35 sediment profiles or outcrops between 860 m a.s.l. and 1945 m a.s.l. were analysed. An altitude‐dependent overall stratigraphy is established and depositional conditions and palaeo‐environments are reconstructed.

An Algorithm for Thermodynamic Parameter Optimization: Application to the Martian Mantle
Geochemistry, Geophysics, Geosystems, 2021 The compilation of thermodynamic models for geophysical applications is such a tedious and complex process that it is generally impractical for researchers to refit parameters in existing models in light of new constraints.

The 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.

The pioneer work of Bernard Kübler and Martin Frey in very low-grade metamorphic terranes: paleo-geothermal potential of variation in Kübler-Index/organic matter reflectance correlations. A review [PDF]
, 2018 Low-temperature metamorphic petrology occupies the P-T field between sedimentary and metamorphic petrology. Two important pillars of low-temperature metamorphism are coal petrology and clay mineralogy.

Routine characterization and interpretation of complex alkali feldspar intergrowths [PDF]
, 2015 Almost all alkali feldspar crystals contain a rich inventory of exsolution, twin, and domain microtextures that form subsequent to crystal growth and provide a record of the thermal history of the crystal and often of its involvement in replacement ...

The 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.

Estimation and uncertainty quantification of magma interaction times using statistical emulation
VolcanicaThe evolution of volcanic plumbing systems, which controls the style and size of eruptions, is largely determined by processes at depths that are not observable.

Petrography and petrology of the Hawaii Scientific Drilling Project lavas: Inferences from olivine phenocryst abundances and compositions [PDF]
, 1996 The Mauna Loa (ML) and Mauna Kea (MK) lavas recovered by the Hawaii Scientific Drilling Project (HSDP) include aphyric to highly olivine-phyric basalts.

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.
