What is Subduction Initiation in Izu-Bonin-Mariana about?
The document discusses the findings from IODP Expedition 352, which drilled four sites in the Bonin outer forearc to study the geological record of subduction initiation related to the Pacific Plate. It highlights the discovery of forearc basalt (FAB) and boninite formations, indicating a transition from seafloor spreading to subduction-related volcanism around 52 Ma. The study provides insights into the geochemical characteristics and evolution of these volcanic rocks, linking them to broader tectonic proc
