State geological mapping, an effective way to the discovery of giant deposits

High efficiency of regional metallogenic analysis while compiling sheets of the State Geological Map­1000/3 and ­200/2 is shown exemplified of the Russian Far East by the discovery of large gold­copper porphyry deposit Malmyzh. The need to strengthen regional geological studies and geological­metallogenic mapping as an important tool for predicting large deposits of unconventional types is stressed. Analysis and prediction of gold­copper porphyry type deposit distribution in volcano­plutonic belts of the Russian Far East are made. Prospects for gold­copper porphyry mineralization in the region have traditionally been associated with the Albian­Paleocene marginal East Sikhote­Alin and Okhotsk­Chukotka volcano­plutonic belts. Great prospects are also associated with the Late Jurassic­Early Cretaceous and Ordovician island arc belts.
