Figure 2. (A-D) Total activity down-core for ²¹⁰Pb (A) CRST 1, (B) CRST 2, (C) FMST 1, and (D) FMST 2 represented by blue lines (diamond markers), with error calculations (5%) shown in red. Supported ²¹⁰Pb values represented by orange (square markers) lines on all graphs, on the left. Respective graphs on the right showing the Natural Log (Ln) of ²¹⁰Pb excess per depth (CF:CS model) with regression equations. (E-H) Total activity down-core for ²¹⁰Pb (E) LGST 1, (F) LGST 2, (G) PMST 1, and (H) PMST 2 represented by blue lines (diamond markers), with error calculations (5%) shown in red. Supported ²¹⁰Pb values represented by orange (square markers) lines on all graphs, on the left. Respective graphs on the right show the Natural Log (Ln) of ²¹⁰Pb excess per depth (CF:CS model) with regression equations.
