| Abstract: | Massive sulfide deposits with two distinct compositions are spatially related to volcanic edifices that penetrate up to 500 m of turbiditic sediment in Escanaba Trough (ET), southern Gorda Ridge. The mineralogy, metal content, sulfur isotope composition, and hydrocarbon content of massive sulfides from ET reflect the extensive interaction between underlying turbiditic sediment and hydrothermal fluid. Pyrrhotite-rich sulfide mounds are inferred to have formed under gentle temperature and chemical gradients related to diffuse, low-velocity flow through disrupted sediment near the sediment-capped hills. |
