Abstract

155 samples from 170 collected at 36 archaeological sites dating between the 15th and 1st century B. C. defines the variation in declination (±20°), inclination (±10°) and ancient intensity (±15-20μT) in Georgia. These new observations are consistent with earlier observations and, when combined with them, these errors are reduced to ±5°, ±4°, and ±5-6μT. The virtual dipole path shows an anticlockwise rotation during this period.
