Unveiling magnetic susceptibility as a proxy in Archaeology: limits for discrimination of magnetic contributions

Popis výsledku v původním jazyce

Magnetic enhancement is primarily driven by strong lithology, and at archaeological sites is often linked with thermal transformations, including areas influenced by heating or burning, micro-refuse materials, as well as particularly remnants of ceramics, daub, fired clay, and feces, which contribute to the formation of pedogenic magnetic particles (Tite and Mullins, 1971). In archaeological soils and sediments, accurately distinguishing between the strongly magnetic fractions of multidomain (MD) and superparamagnetic (SP)ngrains is particularly challenging. Unfortunately, identifying SP grains solely through frequency-dependent magnetic susceptibility is limited, especially when MD magnetite or maghemite is substantial. To address this challenge, we propose a combined approach of physical magnetic separation and laboratory measurements to differentiate between the two contributions. The results are supported by the determination of isothermal remanent magnetization (IRM) acquisition curves to quantify the coercivity components of the tested samples. is work is significant for accurately interpreting the magnetic properties of various materials within a sample, in archaeological contexts and environmental studies where multiple magnetic minerals coexist in the same sample.
