The first occurrence of deep-sea Lower Cretaceous (Albian) sediments in the Pacific Ocean is reported from the Shatsky Rise at 31 degrees 51'N, 157 degrees 20'E. Seismic-profile records indicate that the core was taken between the extensive seismic reflectors A and B. Two hundred meters of unconsolidated sediment lies between the core site and basement (B) and suiggests that the sediment just above basement may be at least as old as Middle Jurassic.
据报道,在北纬31度51分、东经157度20分的 Shatsky 海隆首次发现了太平洋下白垩统(阿尔比阶)深海沉积物。地震剖面记录表明,岩芯取自广泛分布的地震反射层A和B之间。岩芯位置与基底(B)之间有200米未固结沉积物,这表明基底上方的沉积物可能至少与中侏罗世一样古老。
