Correlation of Peat Sections of the Lower Amur Region Based on the Results of Relative Paleointensity Calculations

The article considers the possibility of determining the age of and correlating peat sections by solving the inverse problem of magnetostratigraphy based on findings of comprehensive (palaeomagnetic, petromagnetic, microprobe, and radiocarbon) studies on peats of the Tyapka and Chlya peat sections in the Lower Amur Region. For this, we used the relative paleointensity values calculated following the technique described by Bagina-Petrova. There is no difference in the rate of magnetization fixation among studied peat samples, and the age of magnetization is comparable to the age of the peat deposits themselves. The solution to the inverse problem of magnetostratigraphy using the relative paleointensity values can be used to correlate peat sections among themselves and to estimate the rate of peat accumulation in different periods of the Holocene, even in the absence of radiocarbon dating for one of the correlated sections.
