Figure F49. Composite digital images and magnetic susceptibility (MS) records across the early Eocene Chron C24n clay layer (Y) at Leg 208 sites. The 1-cm and 2.5-cm MS records were obtained from point magnetic susceptibility (PMS) measurements and loop measurements (MSL), respectively. The PMS values were calibrated to the MSL values by multiplying each value with 2.0683 and adding 7.8257.
