Studies on mineralogy and petrology of khondalite in Helan Mountain indicate that the typical metamorphic minerals such as garnet biotite and cordierite have good correlations with the adjacent equivalents, but the correlation between the typical minerals and the host rocks is not apparent.

The garnet migmatitic granite (GMG) was formed by partial melting of Ga-Bi gneiss within Ga-Bi gneiss complex of Archaean khondalites in Daqingshan area, Inner Mongolia, in the process of subhorizontal shearing and granulite facies metamorphism.

Early Precambrian metamorphic complex, composed of khondalite series, BiHb gneiss series, granulite series and metamorphosed plutonic intrusions inside the supracrustal rocks, are well developed in Daqingshan area.
