This study investigates the magnetic mineralogy of a collection of archaeological potteries. Actual magnetic carriers and the domain states of the constituent magnetic fine particles have been obtained from the acquisition of isothermal remanence and low field susceptibility measurements. The magnetic mineralogy of all samples has been dominated by ferrimagnetic mineral (magnetite/magnetite with low titanium content) which is suitable for paleointensity measurement in determining the intensity of the ancient geomagnetic field.

Keywords: rock and mineral magnetism, archaeological pottery

Magnetinės mineralogijos metodais tirtas archeologinių lipdinių šukių rinkinys. Išmatavus izoterminį nuovargį ir jutą silpname lauke, nustatyti tikrieji magnetizmo šaltiniai ir smulkių sudėtinių magnetinių dalelių domeninės būsenos. Visų bandinių magnetinėje mineralinėje sudėtyje dominavo ferimagnetinis mineralas (magnetitas ar magnetitas su nedidele titano priemaiša), tinkamas paleointensyvumui matuoti nustatant senovės geomagnetinio lauko intensyvumą.
