title: East Pacific Rise Near 13{degrees}N: Geology of New Hydrothermal Fields.
abstract: Abundant massive sulfide deposits are present at the crest of the East Pacific Rise near 13 degrees North, where the opening rate is about 12 centimeters per year. Large manganese and helium-3 anomalies in seawater samples, evidence of intense present-day activity of hydrothermal springs, indicate that sulfides are still being produced along this segment of the rise. Massive sulfides also occur on adjacent off-axis seamounts.
