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