Journal Article
Gröcke, D. R., & Waltham, D. (2007). Reply to the comment on “Non-uniqueness and interpretation of the seawater 87Sr/86Sr curve” by John M. McArthur and Paul B. Wignall. Geochimica et Cosmochimica Acta, 71(13), 3387 -3387. https://doi.org/10.1016/j.gca.2007.04.016

Waltham and Gröcke (2006) introduced a new methodology for analysis of the seawater strontium-isotope curve, which showed that changes to a source-flux (e.g., the continental weathering flux) or a source-isotope ratio (e.g., the hydrothermal flux iso...

Journal of Petrology, 48(6), 1119-1154. https://doi.org/10.1093/petrology/egm012

Early Cretaceous tholeiitic picrite-to-rhyolite dykes around Spitzkoppe, western Namibia, are part of the extensive Henties Bay–Outjo swarm, penecontemporaneous with 132 Ma Etendeka lavas 100 km to the NW. Although only intermediate to rhyolitic dyke...

Grain size partitioning of platinum-group elements in road-deposited sediments: Implications for anthropogenic flux estimates from autocatalysts (2007)
Journal Article
Sutherland, R. A., Pearson, D. G., & Ottley, C. J. (2007). Grain size partitioning of platinum-group elements in road-deposited sediments: Implications for anthropogenic flux estimates from autocatalysts. Environmental Pollution, 15(3), 503-515. https://doi.org/10.1016/j.envpol.2007.04.018

Abstract Twelve road-deposited sediment samples were analyzed for platinum-group elements (PGEs) and Pb in the <63 μm fraction of an urban watershed in Hawaii. Three samples were further fractionated into five size classes, from 63–125 μm to 1000–200...

Asymmetric generation of oceanic crust at the ultra-slow spreading Southwest Indian Ridge, 64ºE (2007)
Journal Article

We describe topographic, gravity, magnetic, and sonar data from a Southwest Indian Ridge spreading segment near 64E, 28S. We interpret these to reveal crustal structure, spreading history, and volcanic and tectonic processes over the last 12 Myr. We...

The mechanical behavior of slabs in the mantle transition zone is a poorly understood phenomenon. To obtain a better understanding of the stress and deformation pattern inside subducting slabs, we performed 2D numerical simulations of the subduction...

Isotopic fingerprinting has long been used to trace magmatic processes and the components that contribute to magmas. Recent technological improvements enable us to measure the isotopic composition of progressively smaller samples. This has provided a...
