Its history dates back to the second millennium B.C. The ancient history of Jiroft and its proximity to the River ofHalil Roud have attracted archeologists during the recent decades. So far various historical works have been unearthed from the region of which marble ones are especially noteworthy. Basically, marble works were used more commonly in central plateau of Iran than other ones. The marble works discovered in Jirofl region are only comparable with those from the recently excavation at Shahr-I Sokhta in Zabol. The scientific examination of such works may pave way to identify their internal structures and to compare them in terms of their provenance. The present study will focus on the characterization of marbles discovered in Konar Sandal, Jiroft. In addition to petro graphical studies, XRD and XRF investigations were used to identify the crystalline structures as well as balk chemical composition of the discovered marbles. The obtained results revealed that the major constituents of the discovered marbles in Jiroft were Ca and CaO. The structure of discovered marbles had orderly compact patterns resulted mainly from metamorphism conditions. This structure is actually Unsimilar to those from Shahr-I Sokhta. 展开更多
