Annotated record of the detailed examination of Mn deposits from DSDP Site 38, Leg 5 (Cores 5-38-6)@en

The nonfossiliferous nature of most of the thin sediment sequence at Site 37 had provided little biostratigraphic information for the northern end of the proposed section of sites along 140°W longitude. In an attempt to provide a biostratigraphically more meaningful hole as the high latitude terminus of the meridional section, an additional site (Site 38) was drilled between the Mendocino and Pioneer Fracture Zones.沿西经140°规划的站位剖面北段，37号站位（Site 37）处的多数薄层沉积序列均无化石产出，几乎未提供任何生物地层学（biostratigraphic）信息。为了在该子午向剖面的高纬度端点处获得更具生物地层学意义的钻孔，研究人员在门多西诺断裂带（Mendocino Fracture Zone）与先锋断裂带（Pioneer Fracture Zone）之间钻取了额外站位（38号站位，Site 38）。
