The artifact studied in this paper is a bimetallic sword made of bronze handle and an iron blade, which was excavated from the Tol ancient cemetery, located in Talash city, Gilan province, in 2001 by Mohammad Reza Khaltabari. This research aims to study the technology and pathology of the mentioned object by conducting comparative and archeological studies using the library method, conducting technological studies using the laboratory methods of radiography, metallography, and microstructural observations using a scanning electron microscope (SEM-EDS). The phase analysis of corrosion products was done by X-ray diffraction (XRD), as well as knowing the manufacturing method and identifying the types of damage and corrosion. The result shows that this work belongs to the Iron Age. Also, the tests performed on the two parts of the handle and the blade showed that the material of the iron blade is iron-carbon alloy. The amount of carbon in different parts of the body of blade is not the same and the handle is made of bronze alloy with casting and hammering techniques. It also has a galvanic corrosion effect.

Iranian Azarbaijan and the southern Caucasus have relatively good environmental conditions for the formation of ancient settlements. These include the Lake of Urmia and the coasts of Aras in northwestern Iran and the basins of the Kora River, Mill-Moghan (mountainous areas) in the South Caucasus. The archaeological evidences and recent researches in the two geographical areas provide commonalities and cultural similarities of the period. The main purpose of this article is to introduce traditions of pottery and sites and determine the chronological sequence in the study areas. In order to achieve cultural interactions in the studied geographical area in the Chalcolithic period, the following questions are proposed: What is the status of chronological sequence in the two cultural domains? The main hypothesis in this regard is the existence of chronology is almost identical in the two geographical areas. How do the settlement layers and the sequence of habitation from the Neolithic to the Chalcolithic period in ancient sites show the issue of cultural continuity and transmission? The present writing is done by descriptive-analytical method. As a final result, it can be said that similarities and differences of archaeological data, including the features of pottery, architectural structure, burial etc. point out that by studying areas such as Dalma Tepe, Jolfa’s Kul Tepe, Khoy’s Dava Göz, etc. in Northwestern Iran and Leila Tepesi, Qalayeri, Poylu Tepe, etc in the South Caucasus region have been obtained and in terms of chronology, the millennium BC includes 5000 BC to 3700-3600 BC.
