Leg 193 was the fourth Ocean Drilling Program expedition focusing on understanding subseafloor hydrothermal systems. This program was the first to combine studies of the volcanology, structure, hydrology, mineralization, and microbiology of a subseafloor hydrothermal system hosted by felsic rocks by coring at the PACMANUS hydrothermal field in the Manus Basin, Papua New Guinea. The study examines only the petrology and bulk rock and mineral chemistry of the freshest and most morphologically youthful lava flows recovered from the shallowest drill cores at the four sites occupied during Leg 193. There are subtle but distinct petrographic and geochemical variations between the closely spaced sites.
