base notes	Base PL4 (or, due to LAD, then top of PL3, and alternate for top of Zone N20). NOTE that calibrations imply NO DURATION of Zone PL4 in Atlantic; and extremely brief (but earlier) elsewhere. To avoid confusion on graphics, the base of PL4 has been lowered by 0.01 myr (3.14 Ma, instead of 3.13 Ma in Lourens et al., 2004 compilation). Astronomically tuned as 3.14 Ma from Atlantic ODP Sites 925 & 926. Wade et al. (2011) used this 3.16 Ma age. This LAD is reported as slightly earlier (3.17 Ma) in astronomically tuned eastern Mediterranean and much earlier (3.59 Ma) at astronomically tuned Pacific ODP Legs 111 and 138. Berggren et al. (1995) assigned as base Kaena (3.12 Ma = C2An.1r.0) and noted that Pliocene foram ’Sphaeroidinellopsis seminulina’ LAD occurs about 0.1 m.y. earlier (top of Mammoth, or 3.21 Ma) in the Mediterranean.
