摘要：

Over large areas with high heat flow on the East Pacific Rise the sediments are abnormally poor in aluminum and titanium and rich in iron, manganese, boron, arsenic, cadmium, vanadium and chromium compared to pelagic sediments in general. Most likely the sediments have incorporated precipitates from volcanic emanations that debouch on the crest of the rise. The mineralizing emanations probably originate in the crust or upper mantle, or both. © 1969.
