  • Abbreviations: n, number of samples; D and I, declination and inclination of mean remanence direction; k, precision parameter; α95, circle of confidence (P=0.05); R, reverse magnetization). Present Earth's Field (PEF) directions at the sampling site: D=0°, I=−22°. The mean inclination expected for a Geocentric Axial Dipole (GAD) field for this locality is −0.6°. Sampling latitude=0.3°S and longitude=37.8°E.
