The quantity and value of their metal objects indicate the glory of the Elam era in Iran. This paper examines the data obtained from the geochemical study of silver alloys from the mentioned collections. In this paper, 23 silver samples from the collections have been analyzed by portable XRF method to test the alloy and to answer the two major research questions. Investigation of the data revealed that the presence of the Platinum group elements (PGE) Platinum-Group Elements can be classified as a geochemical model of these objects. Also, the presence of the element iridium could be determined as their chemical fingerprint. Based on these findings, it can be said that the primary ore of the objects of these three collections was supplied from a single geographical area. %> http://jra-tabriziau.ir/article-1-265-en.pdf %P 145-165 %& 145 %! %9 Original Research %L A-10-580-1 %+ Faculty of Conservation and Restoration, Art University of Isfahan, Isfahan, Iran %G eng %@ 2476-4647 %[ 2021
