Figure 58 (continued.) B. Downhole plot of inclinations with magnetostratigraphic interpretation. Polarity: normal = black; reversed = white; undetermined = diagonal lines. Chrons: C2n = Olduvai (1.77-1.95 Ma); C2r.1n = Reunion (2.14-2.15 Ma); C2r.1r and C2r.2r = lower parts of the Matuyama (1.95-2.14 Ma and 2.15-2.58 Ma, respectively); C2An.1n = upper part of the Gauss (2.58-3.04 Ma); C2An.1r = Kaena (3.04-3.11 Ma); C2An.2n = middle part of the Gauss (3.11-3.22 Ma); C2An.2r = Mammoth (3.22-3.33 Ma); C2An.3n = lower part of the Gauss (3.33-3.58 Ma); C2Ar = upper part of the Gilbert (3.58-4.18 Ma).
