苏州花岗岩是长江三角洲腹地唯一的较大规模出露于地表的花岗岩体地貌景观十分典型。本组摄自苏州花岗岩核心区的照片重点呈现了岩体的矿物结构特征,以及垂直节理在花岗岩地貌不同发育阶段中所起的作用。■一线天(天平山)苏州花岗岩核心区的著名景点、由花岗岩垂直节理经外力风化侵蚀发育而成。游人拾级而行时只能侧身通过,抬头仅见一线天光,有穿越龙门的感觉。■垂直节理(天池山)节理与花岗岩岩体的风化侵蚀具有明显的关联性■石隙(天平山)一组垂直节理切穿山岩,经风化侵蚀形成透光现象 Suzhou granite is the only large-scale granite body exposed in the hinterland of the Yangtze River Delta landscape is very typical. This photo taken in the core area of ​​Suzhou granite shows the mineralogical characteristics of the rock mass and the role played by vertical joints in different developmental stages of the granite landform. ■ Tian Xian (Tian Ping Shan) Suzhou granite core area of ​​the famous attractions, by the vertical granite joints formed by external weathering and erosion developed. Visitors can only walk side by side when looking up, only saw a glimmer of sky, the feeling of crossing the gantry. ■ The vertical joints (Tianchi Mountain) are obviously associated with the weathering and erosion of granitic rock mass. ■ A set of vertical joints cut into the rock mass (Tianpingshan) and become translucent by weathering
