base notes	Chron C2r/C2An boundary (= Matuyama Reversed/Gauss Normal boundary) coincides with Oxygen isotope stage 103-104 boundary. "Gauss Normal Chron" (C2An) contains two reversed intervals -- Kaena (2An.1r) and Mammoth (2An.2r). Polarity chron C2An.1n -- Top (= top of Gauss) is 2.581 Ma in Cande-Kent’95 (used here), vs. 2.60 in Hilgen ’91. This 2.581 Ma age (Gauss/Matuyama boundary) was by Langereis, van Hoof & Hilgen (1994, Nature 369: 615).				comp notes
