base notes	Bith-N.n1/MT4n1n -- Bith-N.n1/MT4n1n (base GD4n of Maron et al., 2019) = Base MT4n is tentatively about 75% up in E17 at Guandao (Mingsong Li, in prep 2015; used here). Base CG12n = about 80% up in Cycle s7.8 (used here); or about 5% up in Kocaelia Zone (superzone for entire Bithynian) = just above base of Bithynian (following Hounslow-Muttoni revision; Concise GTS had as base of Bith.) BUT, perhaps CG12n of Szurlies => could be used to give Aegean duration.				comp notes
