Journal Article
Alexander Bentley, R., Buckley, H. R., Spriggs, M., Bedford, S., Ottley, C. J., Nowell, G. M., …Graham Pearson, D. (2007). LAPITA MIGRANTS IN THE PACIFIC’S OLDEST CEMETERY:ISOTOPIC ANALYSIS AT TEOUMA, VANUATU. American Antiquity, 72, 645-656

Teouma, an archaeological site on Efate Island, Vanuatu, features the earliest cemetery yet discovered of the colonizers of Remote Oceania, from the late second millennium B.C. In order to investigate potential migration of seventeen human individual... Read More about LAPITA MIGRANTS IN THE PACIFIC’S OLDEST CEMETERY:ISOTOPIC ANALYSIS AT TEOUMA, VANUATU.

Platinum-group elements (Ir, Pd, Pt and Rh) in road deposited sediments in two urban watersheds, Hawaii (2007)
Journal Article
Sutherland, R., Pearson, D., & Ottley, C. (2007). Platinum-group elements (Ir, Pd, Pt and Rh) in road deposited sediments in two urban watersheds, Hawaii. Applied Geochemistry, 22(7), 1485-1501. https://doi.org/10.1016/j.apgeochem.2007.04.008

This study represents the first detailed investigation of platinum-group elements (PGEs) in road-deposited sediment (RDS) in Hawaii, USA. Thirty-three sample locations, in two urban watersheds in Honolulu, Oahu, Hawaii were sampled. The <63 μm fracti...

Origin of CFB magmatism: Multi-tiered intracrustal picrite-rhyolite magmatic plumbing at Spitzkoppe, western Namibia, during early-Cretaceous Etendeka magmatism (2007)
Journal Article
Thompson, R., Riches, A., Antoshechkina, P., Pearson, D., Nowell, G., Ottley, C., …Niku-Paavola, V. (2007). Origin of CFB magmatism: Multi-tiered intracrustal picrite-rhyolite magmatic plumbing at Spitzkoppe, western Namibia, during early-Cretaceous Etendeka magmatism. 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., Pearson, D., & Ottley, C. (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...
