With the preparation of subjective map of remote sensing like fractures and alteration from regions like Chadormalu, Central Iran, yazd province and around Mashhad, we could introduce some Igneous outcrop for decorative stone as a potential index after a detail field works. Out of all these outcrops 32 of them were selected for detail studies of mineralogy, petrology, geochemistry and rock mechanic. All the above studies were carried out based on A.S.T.M. standard. Based on above studies, 3 outcrops around the Mashhad and 4 outcrops in Chadormalu are very suit of decorative stone. From commercial point of view and A.S.T.M. system as well as scientific the name these rocks ranged from muscovite granite to diorite.
