The greenstone belt is an important tectonic unit in the Archean continental crust. The greenstone belt can be classified into three types according to their unique lithological units: 1） The Barberton type mainly consists of basic-ultrabasic volcanics, with minor felsic volcanics and secondary sediments, lack of andesites; 2） The Superior type is characterized by large amounts of andesites and basaltic andesites, with secondary sediments present. 3） The Dharwar type is characterized by the volumes of clastic sediments and carbonates. The Barberton type greenstone belt is extensively exposed on Earth, showing complex composition and a series of unique petrological and geochemical characteristics: e.g., 1） basic-ultrabasic volcanics are dominant in the sequence of the greenstone belt; 2） komatiites with anomalous potential temperature; 3） the basic volcanics can be divided into the enriched and the depleted basaltic rocks. Although the grade of metamorphism is significantly higher （upper amphibolite to granulite facies）, the Qingyuan greenstone belt is of clear sequence, analogous to the typical Barberton-type greenstone belt in lithological units. The majority of the Qingyuan greenstone belt were formed at 2.5 Ga, coeval with the extensively exposed late Neoarchean granitic gneisses, and no large scale of >2.7 Ga geological bodies exposed in the region. Petrological and geochemical data of the Qingyuan greenstone belt suggests that“ Archean proto-mantle plume model”is favored to account for the generation of the Late Neoarchean basement from Qingyuan area and other regions in the eastern block, North China Craton, not completely the same as the Post-Archean mantle plume in some aspect.
