Figure F11. Average sedimentation rate for the interval 40–46 Ma, given in m/m.y. (after Moore et al., 2004). DSDP and ODP site positions are backtracked to their estimated position at 43 Ma. Site locations are colored according to sediment type for the time interval: blue = carbonate, green = siliceous-carbonate, red = siliceous, brown = clay. Contours are at 1, 5, and 10 m/m.y. Red dashed line = approximate geographic paleoequator based on the sediment archive, with a notable difference compared to the fixed-hotspot based rotation. Two regions of relatively high accumulation occur on both sides of the paleoequator in addition to the primary upwelling center.
