Regional extent
The metamorphic complex of the Danan’ao Group can be divided into two lithologic zones, known as the “Tailuge Zone” and the “Yuli Zone” which were divided by Gu Cangbo in 1963. The two lithologic zones are separated from one another by the Shoufeng Fault. The scope of the “Tailuge Zone” on the western side of the fault is more wider, being possessed of many kinds of metamorphic rocks, including a great amount of marble and gneiss, while the scope of the “Yuli Zone” on the eastern side of the fault is much lesser, comprising largely mica-schist, quartz-mica schist, intercalated occasionally with green schist.
