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.

The granitic enclaves in the central-facies porphyroblastic lava are subvolcanic rocks with forming age of 134.2±1.9Ma. There is another intrusion of subvolcanic rhyodacitic porphyry with age of 136.0±2.6Ma, in the contact zone of the two volcanic cycles in the western part of the Xiangshan complex. The U-Pb ages of the sub-quartz-monzonite porphyry and lamprophyre are 129.5±2.0Ma and 125.1±3.1Ma, respectively. This suggests that the extension in the Xiangshan region, began in K〓, was week, and earlier than that in the coastal region of Zhejiang and Fujian provinces. Extension in K〓 in Xiangshan and neighboring regions was much stronger, forming NE striking large red-downfaulted-basins.
相山中心相碎斑熔岩中的花岗质包体属次火山岩,其成岩年龄为134.2±1.9Ma,在相山西部两火山旋回的界面之间,存在另一类次火山岩的侵位,其成岩年龄为136.0±2.6Ma,岩性为次流纹英安斑岩;次石英二长斑岩及煌斑岩的成岩年龄分别为129.5±2.0Ma及125.1±3.1Ma,说明相山地区的伸展、裂解作用明显早于浙、闽沿海,在K〓就开始了,但规模并不是很大;而K〓时期的拉张作用在相山及其邻区表现的更为强烈,形成了大面积的呈北东向展布的红色断陷盆地。
