Lire la suite >The early history of mature ocean basins is often buried by thick, continent-derived sediment prisms or carbonate build ups and rarely tapped by deep ocean drilling. Drilling in young ocean basins, such as those in the Gulf of California, Mexico, offers insights into the interplay of tectonic, magmatic and sedimentologic processes and into the extent and nature of post-depositional diagenesis/alteration and microbiological activity in the basin fill. The ~4km of biosiliceous to terrigenous sediments and mafic rocks recovered during International Ocean Discovery Program (IODP) Expedition 385 provide an unprecedented record for a nascent ocean basin setting. Expedition results have applications to hydrocarbon exploration and environmental implications for large-scale carbon cycling. A summary of drilling results and shipboard analyses is first presented. This is followed by more detailed look at the nature of the sedimentary record, stratigraphic variation across the basin and integration of previous Deep Sea Drilling Project Leg 64 results. Ongoing and future Expedition research activities are discussed. Opportunities for audience participation in future IODP activities are presented.Lire moins >
