Deskripsi
Time dynamics of geomagnetic field in the region of Chernigov regional magnetic anomaly was investigated using the records of magnetometry observations at 2008 – 2012 years. During these four years the induction module B increased by 140 nT. Against this background trend, the low-level anomalous time variations ΔB were observed regionally (ΔΔB <1.0 nT / year) and locally (ΔΔB> ± 1,5 nT / year). The regional variations are interpreted as a result of magnetization of the magnetic source. The local variations are supposed to be generated by the fluid processes in geodynamic active deep faults of the Dnieper-Donets rift.
