Figure F96. Hole 1109D logs within the 590-720 mbsf interval. A. Natural gamma ray (HSGR) and natural gamma ray minus uranium contribution (HCGR). B. Neutron (APLC) and density (DPHI) porosity. C. Photoelectric effect (PEFL). The clean interval from 673 to 599 mbsf is composed of a carbonate-rich lower unit (Unit L8) and a radioactive sand upper unit (Unit L7). (Continued on next page.)
