Geochemical composition of zircon from various igneous rocks associated with different types of mineralization (Eastern Transbaikalia): development of innovative methods fore casting and searching for metal deposits

The indicator features of zircon from the ore-bearing complexes of Eastern Transbaikalia were established relying on representative factual basis. These features were demonstrated to be highly efficient for determining the potential ore content of granitoids. The values of Ce and Eu anomalies, as well as Yb/Dy in zircons, may be used as indicators of magma oxidation level. Thus, the magmatic rocks of Eastern Transbaikalia with Ce/Ce*>100, Eu/Eu* > 0.4, Yb/Dy > ~4.0-5.0 and (Ce/Nd)/Y > 0.01 may be bearing the classical porphyry type of mineralization. The integrated consideration of the rare earth element composition of zircon and magnetic susceptibility of rocks also may be used as a criterion to search for porphyry type, as well as for some other types of mineralization. It is demonstrated that the high values of magnetic susceptibility (>1.0 x 10-3SI) of magmatic rocks point to the oxidative conditions of rock formation, favorable for the formation of Au-Cu-Fe skarn-porphyry, porphyry and Au-polymetallic types of mineralization.
