Collaborative Research: Elucidating the geologic record of Late Paleozoic subduction initiation along the southwestern margin of Laurentia, southern California and Sonora, Mexico

The principle aim of this project is to document the timing and response of the southwestern Laurentian margin to the initiation of subduction during late Paleozoic time. Although the recycling of lithosphere at subduction zones is a fundamental part of plate tectonic theory, the manner by which subduction zones initiate...

Clastic provenance studies in New Zealand

To determine "source to sink" provenance and dispersal of sand in the Taranaki Basin, for prediction of petroleum reservoir sand distribution and quality, via fingerprinting sand composition in modern rivers and coastal areas associated with mapped basement terranes in the basin's southern hinterland to provide an analogue model for ancient sediment sources and effects of sediment transport. Rationale: The proposed study will help to understand and predi...

The sedimentary/volcaniclastic record of subduction initiation and magmatic arc development at IODP Site U1438

The Izu-Bonin-Mariana (IBM) system is the focus of several 2013-2014 International Ocean Discovery Program (IODP) expeditions (350, 351 and 352) which were designed to answer questions about the fundamental plate-tectonic processes of convergent-margin initiation and crustal development in intra-oceanic settings. The primary objectives of IODP Expedition 351 included discovering the...

U.S. Science Support Program Office associated with the International Ocean Discovery Program (USSSP-IODP)

I have been nominated to serve as the Science Evaluation Panel, Science Chair, for the International Ocean Discovery Program. This grant is for the first year of a normally three-year commitment.
