base notes	Base of Pleistocene is just above the base of Matuyama Chron (reversed-polarity chron C2r) (= top of Gauss; normal-polarity C2An.1n). MIS 104 at 2595 ka; and an Ar/Ar date from Kenya of 2606 +/-6 ka. (Channell et al., 2020). Was 2.581 Ma in Cande-Kent’95 vs. 2.60 in Hilgen ’91 vs. recalculated Ar-Ar 2.61 Ma (Singer, 2014; used here).				comp notes
