Figure F25. Main logs recorded in Hole 1229A. A. The hole diameter is measured by the caliper arm of the density sonde. B. The gamma ray is a measure of the natural radioactivity of the formation. C. Concentrations of potassium, thorium, and uranium derived from the gamma ray counts. D. Ratio of the thorium to uranium concentrations. High values indicate sediments of terrigenous origin. E. Resistivity measured by the Phasor Dual Induction Tool with three depths of investigation. 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 Sonde, SGT = Scintillation Gamma Ray Tool.
