There are three areas position for Dabie Mountains(大别山脉), Mt.Lushan(庐山),Mt.Huangshan(黄山).
Orogeny of Mt.Tienchu roughly induces into following four stages
A.Yanshan movement yanshanian movement of mesozoic
B.Early calnozoic tertiary(himalayan movement)
C.Metaphase Miocene tertiary(himalayan movement)
D.Late Tertiary to early Quaternary(himalayan movement)
天柱山造山運動大體歸納為以下四個階段:
壹..中生代的燕山運動
贰..新生代第三紀早期喜馬拉雅運動
叁..第三紀中期中新世喜馬拉雅運動
肆..第四紀末到第四紀初喜馬拉雅運動
After Tan-Lu fault zone and the Dabie orogen activity influence,airslake erosion and sediment weathering, gravitational force collapse and so on,the surface forms the tonalitic gneiss of granitoid intrusives, Danxia Landform divided by Chinese geomorphologist is landform type with a "anti-U type" .
There are lots of rocks cropping out,outcrop area 120 ㎢(square kilometers). Mt.Tienchu have many kinds of strange rocks and bizarre stones rising highland and big pine-trees.Also, there are many little ridgelines on Mt.Tienchu,which extends from the northwest to the southeast,and in-between these ridgelines there are many valleys. Stream water is always flowing all day long,a popular tourist spot with many valleys waterfalls fantastic rocks and stones. |
