Figure F16. Magnetic susceptibility data for 115 to 135 mcd for Holes 1210A (black line) and 1210B (blue line). The accurate correction factor for these raw instrument values is 0.68 x 10-6. This interval includes the middle Miocene/lower Oligocene unconformity. Hole 1210B data are offset from Hole 1210A data by a constant (40 x 10-6).
