The geomagnetic field recorded in sediments of the Tuzla section (the Krasnodar Territory, Russia) over the time interval 120–70 ka

Abstract

Petro-and paleomagnetic methods are applied to the study of the lower part of the Early Pleistocene Tuzla section on the Black Sea coast of the Taman Peninsula, This part of the section is composed of marine and lagoonal sediments deposited over the time interval 120–70 ka. The measured curves of the variation in the geomagnetic field inclination reveal an anomalous direction dated at ∼110 ka that coincides with a similar anomalous direction in the Eltigen section (Ukraine) correlating with the Blake paleomagnetic event. The significant correlation between the time series NRM0.015/SIRM0.015 (Tuzla section) and the world composite Sint-800 curve indicates that the curve NRM0.015/SIRM0.015 in the interval 110–70 ka actually reflects the variation in the relative paleointensity of the geomagnetic field.
