| Abstract: | Through study and comparison on lead isotope geochemical backgrounds of strata,intermediate-basic dikes,granitoids and alkalibasalts with which gold mineralizations are associated in jiaodong region,the value ranges of lead isotope compositions of each kind of main geological bodies in this region are given. Using plumbotectonics of northern China, we point out that regional granitoids are dominantly stemed from Jiaodong Group metamorphic rocks,Mesozoic granitoids and intermediate-basic dikes associated with gold mineralization are probably the products of remelting and crystallization-differentiation of Jiaodong Group, while some of the pre-Mesozoic granitoids are the products of migmatization of the Jiaodong Group Alkali-basalt in this area formed from southern China mantle by eruptiong after inserting down toward northern China plate. |
