摘要：
The lower continental crust plays a crucial role in continental evolution and mountain building. It is widely accepted that the lower crust is dominated by granulites, mafic or felsic. In the present paper our studies are presented on the geophysical properties of granulites from two adjacent tectonic units, the Late Archean Taihau Complex along the southern margin of the North China craton in Lushan, and the Early Proterozoid Dahe Formation in the Qinling orogen in Tongbai, eastern Henan Province, China. The results indicate that the granulites from the two units were formed within the P-T regime of the lower crust, but in distinct environments.
