Comparative analysis of microscopic images and XRF and EDS results of bricks from arheological sites Mediana and Naisus

This paper describes the archaeological sites Mediana and Naisus during Late Antiquity. Microscopic imagesof  bricks, and the results and analysis of XRF bricks from these archaeological sites are shown. Based on the results, it can be concluded that a similar brick exterior, and approximately the same chemical composition. One reason is, most likely, a similar chemical composition of the soil, because the archaeological sites are geographically close to each other. Another reason  could be the same way bricks were producted, and that the same fuel was used in the kilns.
