Influences of the Archaeomagnetic Variations on Magnetic Structure and Field ?T of Pottery Kilns

P071 Influences of the Archaeomagnetic Variations on Magnetic Structure and Field ΔT of Pottery Kilns Introduction 1 Shape magnetic anisotropy effect causes thermoremanent magnetization (TRM) vectors refraction. It can determine the significant errors of classical archaeomagnetic investigation results. On the basis of magnetic structure of a pottery kilns modelling it is shown that the refraction error correction for the archaeomagnetic dating is necessary and possible. The results of modelling demostrated that the differeces of magnetic field ΔT of kilns determined by archaeomagnetic variations of geomagnetic field are considerable. It can be used for estimation of the ancient geomagnetic field vector
