Figure F29. Main logs recorded in Hole 1230A. A. The hole diameter is measured by the caliper arm of the density sonde. B. The gamma ray log is a measure of the natural radioactivity of the formation. C. Concentrations of potassium, thorium, and uranium derived from the gamma ray counts. D. Resistivity measured by the Phasor Dual Induction Tool with three depths of investigation. E. Preliminary compressional (VP) and shear (VS) sonic velocity. These data will be reprocessed postcruise. F. Density log (red line) compared with density measurements made on core samples (shaded circles) (see "Density and Porosity" in "Physical Properties"). G. Porosity log for the two receivers of the APS sonde compared with porosity measurements made on core samples (shaded circles) (see "Density and Porosity" in "Physical Properties"). HNGS = Hostile Environment Natural Gamma Ray Sonde. SGT = Scintillation Gamma Ray Tool.
