MARs were determined for each site using physical properties data and calculated LSRs. Measurements were averaged through each interval because of poor core recovery and limited shipboard measurements. MARs for Hole 1067A were calculated from 50 physical properties measurements (Fig. F6); 66 physical properties measurements were used for Hole 1068A MARs; 40 physical properties measurements were used for Hole 1069A MARs; 57 physical properties measurements were used for Hole 900A MARs; and 40 physical properties measurements were used for Hole 398D MARs. The physical properties average values used to create Figure F6 are listed in Table T9. Hole 1067A shows decreasing MARs from the middle Eocene to the lower middle Eocene (from 0.2 to 3.5 g/cm2/k.y.). MARs increase in the uppermost lower Eocene (2.3 g/cm2/k.y.), drop off to a hiatus in the upper lower Eocene (<0.2 g/cm2/k.y.), and increase (1.1 g/cm2/k.y.) in the lower Eocene. Holes 1068A, 1069A, 900A, and 398D have similar MAR patterns with a peak (>5.0 g/cm2/k.y.) in the lower middle Eocene, a drop (<2.0 g/cm2/k.y.) in the middle lower Eocene, and a variable increase (1.1-4.1 g/cm2/k.y.) during the lower lower Eocene. The increase in MARs seen at the lower/middle Eocene boundary indicates that sedimentation was greater than subsidence in the rift basin and that turbidity flows were depositing more of their sediments on the basement blocks (structural highs). Overall, the sediments on the IAP show similar MAR patterns with minor variations resulting from increasing distance from sediment source (Hole 1069A) or location on a structural high (Hole 900A).
