Predicting Water Cycle Characteristics from Percolation Theory and Observational Data. [PDF]

open access: yes, 2020
The fate of water and water-soluble toxic wastes in the subsurface is of high importance for many scientific and practical applications. Although solute transport is proportional to water flow rates, theoretical and experimental studies show that heavy ...

The mantle isotopic printer: Basic mantle plume geochemistry for seismologists and geodynamicists [PDF]

open access: yes, 2015
High-temperature geochemistry combined with igneous petrology is an essential tool to infer the conditions of magma generation and evolution in the Earth's interior.

Trace element geochemistry of peridotites from the Izu-Bonin-Mariana Forearc, Leg 125

open access: yes, 1992
Trace element analyses (first-series transition elements, Ti, Rb, Sr, Zr, Y, Nb, and REE) were carried out on whole rocks and minerals from 10 peridotite samples from both Conical Seamount in the Mariana forearc and Torishima Forearc Seamount in the Izu ...

Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

open access: yesThe Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

The fate of William Whewell’s four palætiological domains : a comparative study [PDF]

open access: yes, 2019
In 1847, the British polymath William Whewell pointed out that the sciences for which he, in 1837, had coined the term “palætiological” have much in common and that they may reflect light upon each other by being treated together.

Carbonate microfacies and transgressive‐regressive sequences of Oxfordian shallow‐water limestones (Korallenoolith, Lower Saxony Basin)

open access: yesThe Depositional Record, EarlyView.
The Bisperode section is one of the most expanded and complete sections with shallow‐marine Oxfordian strata in the LSB. This study provides a reference record for shallow‐marine settings and allows for the correlation of the strata from the LSB with Oxfordian deposits distributed elsewhere in the world.

Printing non-Euclidean solids

open access: yes, 2017
Geometrically frustrated solids with non-Euclidean reference metric are ubiquitous in biology and are becoming increasingly relevant in technological applications. Often they acquire a targeted con- figuration of incompatibility through surface accretion

Geochemical Signatures of Potassic to Sodic Adang Volcanics, Western Sulawesi: Implications for Their Tectonic Setting and Origin [PDF]

open access: yes, 2016
DOI:10.17014/ijog.3.3.195-214The Adang Volcanics represent a series of (ultra) potassic to sodic lavas and tuffaceous rocks of predominantly trachytic composition, which forms the part of a sequence of Late Cenozoic high-K volcanic and associated ...

Trace elements, rare earth elements and isotopes of poorly preserved fossils from lower Cretaceous carbonates (Eastern Black Sea): Implications for early diagenetic alteration

open access: yesThe Depositional Record, EarlyView.
Analysing Rare Earth Elements (REEs) and other trace elements together with stable isotope data in poorly preserved belemnites can provide valuable insights into early diagenetic pathways, water‐interaction processes, and even potential redox conditions.

The FOREGS Geochemistry Task Group 1994-1996 [PDF]

open access: yes, 1996
The Forum of European Geological Surveys (FOREGS) includes geological surveys from 33 European countries and is responsible for co-ordinating geological survey activities in Europe. The FOREGS Geochemistry Task Group was established in 1994 as part of
