Oxygen Isotope Variations of Basaltic Lavas and Upper Mantle Rocks [PDF]
This chapter summarizes the oxygen isotope geochemistry of terrestrial basalts and their mantle sources, including the conceptual framework for interpreting such data and the phenomenology of known variations.

Platinum group element mineralization at Musongati (Burundi) : concentration and Pd-Rh distribution in pentlandite [PDF]
The mafic-ultramafic intrusions of the Karagwe-Ankole belt in Burundi are considered as a new potential source for platinum group elements (PGE). The intrusions have mainly been studied for their PGE potential with regard to PGE concentration, but the ...

The Bundelkhand craton in India preserves important records of archean geological evolution, where several ultramafic rocks belonging to the Babina Greenstone Belt (BGB) occur as isolated and oval shaped bodies.

Release of potassium from rock powder by the yeast Torulaspora globosa
The alteration of minerals in rocks and the availability of elements for plant nutrition require long periods of time, and microorganisms are thought to induce the release of potassium and phosphate from rocks.

Seismic wide-angle study of accreted Proterozoic crust in southeastern Wyoming [PDF]
A seismic wide-angle xperiment was conducted in southeastern Wyoming, USA to investigate the seismic character of a postulated Proterozoic magmatic arc south of the suture (Cheyenne Belt) to the Archean Wyoming Province.

Ex-situ mineral carbonation: resources, process and environmental assessment (Carmex project) [PDF]
This article presents the main results of the Carmex project (2009-2012), whose purpose was to review the feasibility of ex-situ mineral carbonation in terms of resource availability, performance of the aqueous mineral carbonation process and life cycle ...

Oxygen isotope geochemistry of the second HSDP core [PDF]
Oxygen isotope ratios were measured in olivine phenocrysts (~1 mm diameter), olivine microphenocrysts (generally ~100–200 µm diameter), glass, and/or matrix from 89 samples collected from depths down to 3079.7 m in the second, and main, HSDP core (HSDP-2)

Abstract In addition to high‐temperature vents, lower‐temperature flow (LTF) (<300°C) is abundant along mid‐ocean ridges and contributes globally‐important fluxes of heat and water along with largely‐unconstrained geochemical influences on the ocean. We examined the impact of on‐axis LTF on the chemical composition of the overlying water column (<40 m ...
