base notes	Major expansion of N.Hemis. glaciation begins near Gauss/Matuyama boundary [accepted in 2009 for base of "Quaternary", hence base of revised "Pleistocene"]. NOTE: Was at 2.588 Ma, which is mid-point of underlying Sapropel, which Rio et al (1998) had recommended to also be age of base-Gelasian. However, Gibbard and Head (2009) noted the offset; therefore recommended 2.58 (not 2.59); which is used here.				comp notes
