Beigu mountain tunnel is constructed in mica schist, chlorite schist, and leptynite (Figures 2(b), 2(c), and 2(d)).
The main rock types are biotite-bearing plagioclase gneiss, plagioclase hornblende gneiss, amphibolite, and biotite-bearing plagioclase leptynite. The structures in the regional area are complex and are mainly affected by the northern margin fault of the NCC (Kangbao-Chifeng fault) and the large-scale sinistral strike-slip motion of the Dunhua-Mishan fault.

The geological features encountered are as follows: gneiss to garnet, gneiss to amphiboles, leptynites, leptynites garnetified, and garnets.
They locally contain intercalations of crystalline limestones and dolomites (marbles), amphibolites, amphibole schists, quartzite and quartzite schists, graphite quartzites and mica schists, porphyroids and leptynites.
