岩浆活动在太行山地区对峰林、嶂谷地貌形成过程的控制作用

Control effect of magmatic activity to formation procedures of peak-forest and narrow gorge landform in Taihang Mountain

太行山地区峰林、嶂谷的形成受节理面近垂直的追踪张节理的直接控制。根据物理模拟实验,岩浆侵入过程中可形成追踪张节理,因而推断控制峰林、嶂谷形成的追踪张节理以局部岩浆活动形成为主,板块域内的区域应力场作用为辅。同时指出,在具有侵入岩浆活动、地层层面近水平的地区,可能是寻找未发现的旅游资源的远景区。

There are some national geological parks in Taihang mountain area, where develops peak -forest and narrow gorge landform. There exist double - layer geological structural rocks, of which the upper belong to sedimentary and metamorphic rocks in nearly horizontal bedding plane. It is young for the lower magmatic rocks in age. The study shows that the peak - forest and narrow gorge landform is directly controlled by the near - vertical trace tensional joints in joint surface. According to the physical simulation experiment, the trace tensional joints could be formed when magma intruded, meanwhile, the regional stress field could make some assist effects. It is also pointed out that it may be a prospective area of tourism resources for the strata in nearly horizontal bedding plane with magmatic activity in the area.
