Bataille Thumbail Bataille et al. (2012), Mapping multiple source effects on the strontium isotopic signatures of ecosystems from the circum-Caribbean region

Strontium (Sr) isotope ratios (87Sr/86Sr) can provide insights into a range of environmental processes. Previous authors have mapped 87Sr/86Sr in both bedrock and water across large spatial scales, but these efforts have assumed that the weathering of primary minerals in bedrock is the only source of environmentally available Sr. Bataille et al.





Yuri_Taran IEDA Data Rescue Mini-Award: Legacy Russian Volcanic and Hydrothermal Gas Data

Geochemical analyses of volcanic and hydrothermal gas samples from 20 publications have been translated and compiled by Tobias Fischer (DCO DECADE; University of New Mexico, USA), with expert Russian gas geochemist Yuri Taran (Universidad Autonoma de Mexico; pictured at right), Elena Kalacheva (IVS, Kamchatka) and Nicole Thomas (UNM). These data, which were previously… Read More



Carmichael Thumbnail Carmichael (2014), Chemical Analysis of Silicate Rocks: A Manual

The late Dr. Ian S. E. Carmichael (pictured) was known as "a giant in the field of igneous processes and volcanoes." His groundbreaking work included the development and use of a suite of analytical techniques for the determination of silicate rock composition. He compiled these… Read More



Kelley Thumbnail Kelley et al. (2013), Composition of plume-influenced mid-ocean ridge lavas and glasses from the Mid-Atlantic Ridge, East Pacific Rise, Galapagos Spreading Center, and Gulf of Aden

Plumes of mantle-derived material impinge on or otherwise interact with oceanic spreading centers in many locations throughout the world. These interactions often result in unique geochemical signatures in ridge lavas due to variations in mantle source composition. Kelley et al. (2013) presents high resolution and high precision trace element data for 573 samples of variably plume-influenced… Read More



Delano Thumbnail IEDA Data Rescue Mini-Award: Lunar Samples

An enduring legacy of the Apollo program is the lunar sample collection that is currently maintained and curated at Johnson Space Center in Houston, TX. These samples, obtained at tremendous cost and great risk, are the only samples that have ever been returned by astronauts from the surface of another planetary body.
