Archaeomagnetic is an interdisciplinary field that bridges geophysics and archeology. It evaluates the changes in the Earth’s magnetic field over the periods of human existence. In this method, scientists use the sporadic changes in the Earth’s magnetic field and some features of archaeological artefacts that can acquire the direction and intensity of the Earth’s magnetic field. Ultimately, the average age of an archaeological artefact is determined. The samples in these study were collected from the archaic sites of Kul Tape, Hadi Shhr, Jolfa, and DavaGoz, Khoy. The samples were dated back to the Neolitic and the Kura- Araxes II period’s (2638-5215 B.C). These samples had been dated previously by the 14C method. For this purpose, the measurement method of mass magnetic susceptibility was used with the Capabridge device. To determine the size of minerals, frequency-dependent magnetic susceptibility was used by the Bartington device, magnetic minerology was studied by Curie temperature determination (CS3 device), the second magnetization was demagnetized and the primary magnetization was obtained by thermal demagnetization. Regarding the abundance of ferromagnetic minerals, the samples showed similar magnetic behavior. Furthermore, the sizes of ferromagnetic minerals were a compound of super-paramagnetic and larger particles. The magnetic carriers in all samples were magnetite and titano-magnetite. The absence of hematite. This was an impediment to determining the archaeomagnetic property. There is a good compatibility between the reference curve of changes in the archaeomagnetic tendency for the studied range of time when considering the results of neighboring sites (Balkan) over the same era and duration. Despite the various lacks and deficiencies, this reference curve can be used for determining the age of heated samples and objects over the given range of archaic period in this study and over a specific spatial range of 1000 km around these two sites.
