524 SEDIMENTARY ENVIRONMENTS/Contourites Figure Core photos from ODP Leg 181 in the SW Pacific Gateway From Carter RM, McCave IN, Richter C, et al (eds.) (1999) Proc ODP, Initial Reports, Vol 181 Available from: http://www odp.tamu.edu/publications/181_IR/181ir.htm (A) Core 181 1121B 1H CC, 50 82 cm from the Campbell Drift showing brownish yellow sand with extremely sharp bottom contact (75 cm) with the underlying yellow clay This sand bed exhibits no grading and is interpreted as a contourite deposite left behind after that an intense winnowing removed the fine material (B) Core181 1122C 44X 2, 50 85 cm in the left (north) bank levee of the abyssal Bounty Fan showing greenish grey fine sand and silt beds that commonly exhibit sharp scoured top and bottom contacts with the interbedded mottled, dark greenish grey pelagic/hemipelagic bioturbated silty clay The conspicuous planar and cross laminations, representing concen trations of foraminifera and carbonate debris, suggest a stronger, episodic benthic flow regime, in contrast to that of the decelerating turbidity currents (C) Core 181 1124C 37X 2, 20 40 cm from the Rekohu Drift showing light greenish grey clay bearing nannofossil chalk with flaser like interbeds and laminae suggesting the presence of sediment moving bottom currents
