Annotated record of the detailed examination of Mn deposits from DSDP Site 159, Leg 16 (Cores 16-159-6 and 16-159-12)@en

DSDP 159 is one of a series of sites in the eastern equatorial Pacific on the west flank of the East Pacific Rise. It was selected by the Pacific Site Selection Panel on the premise that if hydrothermal processes on the crest of the East Pacific Rise supply the transition metals, a broad zone of such deposits should be present immediately above basement over the entire flank of the Rise.深海钻探计划（Deep Sea Drilling Project, DSDP）159站位是东太平洋海隆（East Pacific Rise）西翼东赤道太平洋海域一系列站位中的一员。该站位由太平洋站位遴选小组选定，遴选前提为：若东太平洋海隆峰顶的热液作用可为过渡金属提供补给，则在海隆整个侧翼的基盘上方区域，理应存在一片分布广泛的此类沉积矿床带。
