Abstract:
The cumulative classified count record (in percentages) over ~2 cm resolution of each petrologically identified IRD lithologies within the stratigraphic units of Heinrich Layers and Interlayers (about ~10 to 20 samples of 10 cm3) represent the >1 mm IRD particles in ~100 to 200 cm3 of sediments. The data are expressed in percentage to facilitate correlation and also avoiding exaggeration of less signification IRD particle abundances. IRD accumulation rate per area and time was derived from IRD counts and sedimentation rate of each stratigraphic unit.
