Conclusion

Overlapping sites and objectives were drilled on the three expeditions comprising NanTroSEIZE Stage 1. Because specific teams of specialists were onboard and collaborated on core and log analysis during each separate expedition, the site reports are, by necessity, published separately in this volume. This introduction and summary of some of the results highlights a few overarching aspects of the drilling results. Taken as a whole, the NanTroSEIZE Stage 1 transect of six major sites has documented the structure, sedimentology, tectonic history, present-day stress conditions, and other aspects of the margin. The overall principal goal of characterizing the fault systems and their wall rocks in the aseismic regime and sampling the older prism beneath the Kumano forearc basin has been achieved, setting the stage for deep riser drilling to the seismogenic zone.
