Table T2. Main criteria used for distinguishing lithostratigraphic units.

Unit Depth
(mbsf) Characteristics

I
0-4.6
Nannofossils = A; foraminifers = A-C; quartz/feldspar = P; beds <0.5 m distinguished by colors; unit sits on unconformity.

II
4.6-11.2
Nannofossils = A; foraminifers = A-C; glauconite = P; beds >1.0 m; colors less distinct than in Unit I.

III
11.2-54.9
Nannofossils = A; foraminifers = C; sponge spicules = P; bedding differentiation weak.

IV
54.9-220.7
Nannofossils = A; foraminifers = P; bedding very poor.

Unit	Depth (mbsf)	Characteristics
I	0-4.6	Nannofossils = A; foraminifers = A-C; quartz/feldspar = P; beds <0.5 m distinguished by colors; unit sits on unconformity.
II	4.6-11.2	Nannofossils = A; foraminifers = A-C; glauconite = P; beds >1.0 m; colors less distinct than in Unit I.
III	11.2-54.9	Nannofossils = A; foraminifers = C; sponge spicules = P; bedding differentiation weak.
IV	54.9-220.7	Nannofossils = A; foraminifers = P; bedding very poor.

Note: A = abundant, C = common, P = present.
