Stratum near the bridge foundation is rhyolite porphyry in late Jurassic period. A little of slope eluvium exists on the top of the mountain, which is 200 m long and 80 m wide, and its all sides face to sea. The integrality of rock mass of the mountain is relatively poor because of the effect of some faults and other structural fissures.
