ABSTRACT: Following the designation of a GSSP for the Paleocene/Eocene boundary in the Dababiya Quarry section in the southern Nile Valley of Egypt a continuously cored well was drilled in the hope of recovering better preserved lithologies and microfossils than in nearby outcrops. The well was continuously cored from the lower part of the El MahmiyaMember of the Esna Shale and penetrated the Dababiya Quarry Beds, El Hanadi Member of the Esna Shale, Tarawan Chalk and Dakhla Shale to a total depth of 140 m. Geophysical logging included Natural Gamma Ray (GR), Single-Point Resistivity (PR), Self-Potential (SP), and Resistivity, Short Normal (SN) and Long Normal (LN). Magnetic susceptibility was also measured. The Paleocene/Eocene and Cretaceous/Paleogene (K/P) boundaries. were recorded as sharp peaks on all logs particularly theGRand PR, and in themagnetic susceptibility log.Accordingly, in addition to the paleontological and lithological studies, the two boundaries are well delineated/characterized from the geophysical logging and magnetic susceptibility logs. This paper presents a brief description and discussion of the logging andmagnetic susceptibility characteristics of the subsurface sequences encountered in the Dababiya Quarry Corehole (DQC).
