Summary: Site U1528 (proposed Site UC-1A) is located inside a small (∼40 m diameter at the top; ∼25 m diameter at the bottom) pit crater at the summit of the Upper Cone of Brothers volcano at a water depth of 1228 m. The primary objective at this site was to drill into the upflow zone of a Type II hydrothermal system strongly influenced by magmatic degassing. In this area, relatively gas-rich, very acidic fluids are being discharged, resulting in advanced argillic alteration. Site U1528 was designed to address important Expedition 376 objectives related to the role of magmatically influenced hydrothermal fluids in transporting metals to the seafloor and to provide a comparison of fluid-rock reactions with the seawater-dominated Type I hydrothermal system drilled at Sites U1527 and U1530.
