Geologists and archaeologists say that the stone was made by heating silt from the Tigris and Euphrates rivers to melting temperatures and then slowly cooling it “to produce rock - hard slab resembling a type of volcanic rock called basalt, ” reports The New York Times.
Geoloogid ja arheoloogid ütlevad, et see kivi valmistati Tigrise ja Eufrati jõe mudast, mida kuumutati sulamistemperatuurini ning jahutati siis aeglaselt, nii et ” sellest saaks kivikõva plaat, mis meenutab vulkaanilist kivimit basalti ”, teatab ” The New York Times ”.
