چکیده انگلیسی
Its petrographical property is remarkable and quite interesting. In order to perform petrographical studies on Oltu-stone, ten samples were taken from two locations a few kilometers from the town of Oltu which is northeast of Erzurum city in eastern Turkey. Polished briquettes and thin sections were produced from the samples for petrographical examination under a coal microscope. SEM and EDS analyses were also conducted. Internal cellular structures can clearly be traced in fluorescent mode. The great strength of the stone has always incorrectly led to the conclusion that its genesis is unlike the genesis of coal. However, fluorescent light plainly revealed detailed cellular structures. With the aid of fluorescent light, suberinite textures and silicate filling of the cell cavities were clearly observed.
