| Abstract: | Shuiquangou-Hougou syenite complex is one of the largest subalkaline rock bodies in the Northwester Hebei. It can be divided into 5 stages of intrusion and 8 types of intrusive rocks.Kfeldspar and albite are main rockforming minerals.In addition,there are aegirineaugite and diopside.Petrochemistry of the rock body is similar to that of the subalkaline syenite in the world.Petrology and petrochemistry have revealed that shuiquangow-Hougou syenite complex was formed by anatetic magma. |
