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。
