The Study of Geochemistry and Tectonic Environment of Monzogranite in Huangtuliang Area,Northwest Hebei

摘要：

　　Based on the geological and geochemical studies in Huangtuling monzogranites,they are suggested that the granites in this area are the Peraluminous plutons.The REEs compositions of the samples are similar, showing high ΣREE contents, with enrichment in LREEs, light and heavy REEs fractionations are obvious and negative Eu anomalies.They show enrichment in K, Ba, Th and depletion in Ta, Nb, P, Zr and Ti.Depending on the geochemical characteristics and the tectonic setting diagrams of Ta-Yb、 Nb-Y、 Rb-(Y+Nb) and Rb-(Yb +Ta) of Monzogranite, we can conclude that granite formation environments in this region are more complex, both are the formation of orogenic environment, and are the non-formation of it, and they have the realationship with Middle Triassic North China Craton.
