Abstract

Iron-rich sediments chemically similar to those forming at present on the crest of the East Pacific Rise have been found just above basement at widely separated drill sites in the eastern equatorial Pacific, including three sites of Leg 16 of the Deep Sea Drilling Project. These sediments were probably formed when the basement was at the crest of this rise and have moved to their present location as a result of sea-floor spreading.

摘要

在赤道东太平洋相距甚远的钻探点，包括深海钻探计划第16航次的三个钻探点，在基底之上发现了富含铁的沉积物，其化学性质与目前在东太平洋海隆顶部形成的沉积物相似。这些沉积物可能是在基底位于该海隆顶部时形成的，并由于海底扩张而移动到了它们现在的位置。
