The granitic rocks are an importent part of the Qiugyuan Archean green- stope-granite terrene, constituting a steady Archean craton together with the greenstone rocks. This paper deals with the discussion about the petrogenesis of the granitic rocks in accordance with the REE geochemistry. The granitic rocks in this terrene can be classified into two types: granitic and tonalitic. Their chondrite-normalized REE distribution patterns are comparable with A and B`group of the Amitzoq grauitic gnessic rocks. The Melinghong tonalitic diapir exhibits a typical REE plot of Archean tonalite, its HREE is strongly depleted, near CARB. CHOND..On the basis of rare elements and field geologi- cal investigation it is possible that the both gxoups derived from a common parental magma. The tonalitic parental magma was derived by partial mel- tig of the Iower crust, and fractional crystallization was displayed by the widespread activity of two types of the granitic rocks. The gramtlite-charuo- ckite series are the crystal basement of the greenstone belt, which occurs as arc around the charnockite. In the light of the REE and LIL model calcula- tion, the charnockite in Xianjipchang is probably the result of partial melting from the basic crust. After this it was migmated again, or many times.
