| Abstract: | There are five granitic intrusions which are biotite monzogranite in the district of Xihuashan.They are divided into three phases,show high Si,alkaline,poor Ti,Fe,Mg,Ca,P,belong to strongly-peraluminous high-K calc-alkaline series,ACNK>1.1.All this imply that the granites are S-type granite.Zircon U-Pb dating age is(150~153)Ma.The average of TREE is 237.15×10-6,higher than Naling granite(229.68×10-6).γ2-1a5,γ2-1b5,γ2-35 represent a LREE-rich curve while γ2-2a5,γ2-2b5 show a HREE-rich curv,but Eu negative anomaly are obvious in all granites.The granites geochemical characteristics and regional tectonic evolution background indicate that the rocks were formed in a post-orogenic extension environment,lithospheric thinning and extension tectonic background. |
