		Core, section, interval (cm)			Depth (mbsf)			Core, section, interval (cm)			Depth (mbsf)
		Top	Base		Top	Base		Top	Base		Top	Base
I	IA	1H-1, 0	7H-CC, 17		0.0	62.0							Skeletal wackestone to grainstone with planktonic foraminifers, pteropods, and variety of microfossils. Light gray to greenish gray.	Hemipelagic setting (drift deposits)
	IB	7H-CC, 17	22H-5, 18		62.0	200.6							Mudstone to skeletal packstone with predominantly planktonic foraminifers. Light greenish gray to olive-gray.	Hemipelagic setting (drift deposits)
II	IIA	22H-5, 18	?		200.6	224.8		?	4R-1, 55		?	225.0	Skeletal packstone to grainstone, predominantly fine grained with planktonic foraminifers, abundant larger benthic foraminifers, and neritic material. White to pale brownish white and slightly dolomitized.	Periplatform setting
	IIB							4R-1, 55	15R-1, 0		225.0	330.3	Skeletal packstone to grainstone and skeletal grainstone/floatstone to rudstone, coarse grained, with lepidocyclinids, rhodoliths, and corals. White to pale yellow and slightly dolomitized.	Proximal slope, periplatform setting
	IIC							15R-1, 0	22R-1, 0		330.3	397.6	Skeletal grainstone to packstone (brownish white), fine grained, and silt-sized packstone to grainstone with clay. Light gray to light olive-gray and slightly dolomitized between 330 and 360 mbsf.	Periplatform setting
III	IIIA							22R-1, 0	27R-1, 144		397.6	447.1	Mudstone to silt-sized packstone with clay, cyclic alternation of lithologies. Light to dark greenish gray and slightly dolomitized. Occurrence of small fining-upward sequences.	Hemipelagic (deepening upward?); cyclic sedimentation
	IIIB							27R-1, 144	33R-1, 23		447.1	503.6	Silt-sized packstone to grainstone with more abundant glauconite (at base of subunit) and less clay than Subunit IIIA. Light greenish gray to light olive-gray and slightly dolomitized.	Hemipelagic (deepening upward?); cyclic sedimentation, some influence of distal periplatform shedding?
IV								33R-1, 23	34R-1, 23		503.6	513.2	Skeletal floatstone/rudstone with larger benthic foraminifers (Cycloclypeus sp.) and rhodoliths. White to light greenish gray.	Deep shelf facies
V								34R-1, 23			513.2		Olivine basalt with smectite-, hematite-, feldspar- and opal-(?) filled veins. Dark gray.	Basement
