The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 229-246., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Landslide-Induced Weathering in Tectonically Active Mountains: Evidence From Dissolved Radiogenic Uranium Isotopes

open access: yesFrontiers in Earth Science, 2022
Understanding weathering processes in landslide-dominated catchments is critical for evaluating the role of landslides in chemical weathering and the global carbon cycle.

Radiogenic isotope: not just about words

open access: yesApplied Geochemistry, 2022
This viewpoint is a short comment on gender issues with isotope terminology. The terms "parent"/"daughter" should be avoided in favor of the more descriptive "precursor ion" and "product ion" terms.

Distinct iron cycling in a Southern Ocean eddy

open access: yesNature Communications, 2020
Eddies are common ocean features that isolate large swaths of seawater, but it is unclear how they influence productivity of phytoplankton trapped inside.

Radiogenic heat production in granitoids from the Sierras de Córdoba, Argentina

open access: yesGeothermal Energy, 2021
One of the most important processes of heat generation from the Earth's interior is the radioactive decay of isotopes. The main hosts of the major radiogenic elements U, Th and K in the crust are granitoids.

Evidence of hydrological control of Sr behavior in stream water (Strengbach catchment, Vosges mountains, France) [PDF]

open access: yes, 2002
Strontium and particularly 87Sr/86Sr ratios in stream water have often been used to calculate weathering rates in catchments. Nevertheless, in the literature, discharge variation effects on the geochemical behavior of Sr are often omitted or considered ...

Amphibole: A major carrier of helium isotopes in crustal rocks [PDF]

open access: yes, 2016
The first evidence for a specific role of amphiboles in He isotope balance of crustal rocks was presented in early contributions by Gerling et al. (1971, 1976).

Radiogenic p-isotopes from type Ia supernova, nuclear physics uncertainties, and galactic chemical evolution compared with values in primitive meteorites [PDF]

open access: yes, 2014
The nucleosynthesis of proton-rich isotopes is calculated for multi-dimensional Chandrasekhar-mass models of Type Ia supernovae (SNe Ia) with different metallicities.

Human and faunal stable and radiogenic isotope data from four Bahraini and three Jordanian assemblages c. 5300 B.C. to 1500 AD

open access: yesData in Brief, 2021
This dataset presents carbon, nitrogen, oxygen (carbonates and phosphates) and strontium data from human and faunal remains from that portion of seven assemblages from Jordan and Bahrain currently curated at the Smithsonian Institution's National Museum ...

The Use of Intrinsic Markers for Studying the Migratory Movements of Bats

open access: yesAnimals, 2021
Mortality of migratory bat species at wind energy facilities is a well-documented phenomenon, and mitigation and management are partially constrained by the current limited knowledge of bat migratory movements.
