西秦岭温泉岩体是壳幔混浆的产物。寄主岩石以贫CaO富FeOtot为特征 ,ANKC值大于 1 1 ,NK A值均小于 0 9,属铝过饱和钙碱性系列岩石 ,系上地壳碎屑岩类熔融而成。基性端元暗色微细粒镁铁质包体及基性岩墙 ,高Na2 O及K2 O ,而贫FeOtot。两类岩浆混合形成的混浆花岗岩 ,岩石地球化学介于两个端元并有显著的过渡特征和依从关系反映了重要的岩浆混合信息
West Qinling Hotspring rock mass is the product of crust-mantle mixing. Host rocks are characterized by poor CaO-rich FeOtot with an ANKC value greater than 1 1 and a NK A value less than 0.9, which belongs to an over-saturated series of Ca-Al basic series of rocks and is formed by the melting of crustal clastic rocks. Basic terminal dark microparticle mafic inclusions and basic dikes, high Na2 O and K2 O, and poor FeOtot. The mixed magmatic rocks formed by the two types of magma are characterized by the fact that the rock geochemistry is between two end units and has significant transitional features and dependencies that reflect important magma mixing information
