Geochemical and petrographic approach for the origin of the limestone blocks of thewalls of the Great Temple of Hattusha, Çorum (N-Turkey)

The socle stones of the Great Temple in Lower City Hittite capital city, Hattusha (Çorum Province) have been studied for first time by petrographic and geochemical analysis (Sr isotope, stable trace element geochemistry). Study objectives were to determine carbonate facies stone samples used investigate their possible sources. Petrographic 10 limestone presents five clusters different microfacies. Stable isotope (δ13C δ18O) displayed presence 5 groups parallel with analysis. Trace same considerable difference among 87Sr/86Sr ratios change between 0.70697 0.706867. Based on results, it can be stated that building using are from probably This is great importance better understand construction process acquisition materials.
