We studied geochemistry and geochronology of thirty granitoid rocks from five porphyry deposits and eighteen porphyry occurrences. Result of our study on geochemistry and geochronology of granitoid rocks, related with porphyry deposits, similar with some records on age and geochemistry in south Mongolia and it is vital importance for further study of Central Asian Orogenic Belt as well as reconstruction of paleo geo environment and related porphyry mineralization.
