The word "rock" is composed of mountain and stone
When it comes to mountains, the Five Mountains are inseparable in China
Which rocks are the five mountains made of?
Eastern Mount Tai
Mount Tai is the "top of the five mountains"
From Qin Shi Huang to Qing Dynasty
There are 13 generations of emperors who visited Mt.
There are also 24 emperors who sent officials to worship 72 times.
The rocks that make up the main body of Tarzan are the "Tarzan Miscellaneous Rocks"
It is composed of Taiyan metamorphic system and a large number of late Taiyan intrusive miscellaneous rocks
Mainly mixed rocks, mixed granites and various gneisses
About 2-2.5 billion years old
Some zircons found in the main peak Yuhuangding are the oldest rocks in Taishan
About 3.7 billion years old
The current landscape of Taishan was formed about 30 million years ago
It is still uplifting at a rate of 0.5 mm/year
▲ Xiyue Huashan ▲
Mount Hua is the birthplace of Chinese civilization
"The name "China" and "Huaxia" originates from Mt.
The highest elevation of the five mountains (2154m)
It is 15 kilometers long from east to west and 10 kilometers wide from north to south
Mount Hua is also the most dangerous of the Five Mountains
Huashan is a huge block of granite
The top of Huashan is a coarse-grained (5 mm in size) porphyritic granite
The middle part is medium-grained (2-5 mm in size) granite and gneissic granite
The oldest rocks of Mount Huashan are about 600-1 billion years old
70 million years ago, the bedrock of Huashan was exposed
The current landform was formed about 2-3 million years ago
▲ North Mount Everest ▲
Mount Heng Shan ranks second in elevation among the five mountains (2016m)
24 emperors have been here and 13 emperors have fought here
The rock layer of the main peak area of Heng Shan is ancient Cambrian Ordovician limestone
formed 500 million years ago
Other ancient metamorphic rocks, quartzite, quartz schist, etc.
Mt. Everest has been formed for 2.8 billion years
Repeated uplifting and subsidence, winding and bumpy
The current landscape of Mount Everest was formed 2.6 million years ago
▲ Zhong Yue Song Mountain ▲
The mountain has been continuously and completely exposed for about 3.6 billion years
of the past five geologic periods: the Tertiary, the Proterozoic, the Paleozoic, the Mesozoic and the Cenozoic.
The stratigraphy of five geological history periods
The stratigraphic sequence is clear and the tectonic traces are typical.
It is called "five generations together" by the geological community
In fact, it is a complete stone book of earth history
When the land of China was still a sea
Mt. Songshan emerged
Mt. Songsan is the "ancestor of all mountains"
The main rock of Mt. Song is quartzite
It was formed 1.8 billion years ago
The oldest rocks are the granite greenstone system
Metamorphosed by crustal movement to form a gneiss base
The base is overlain by quartzite
Mt. Songshan was formed six times as land and six times as sea
Started with ocean and ended with land
The current geomorphology of Mt.
It was the first of the five mountains to take shape
Since about 60 million years ago
Nanyue Mountain rose to receive weathering
A red weathered crust of thick granite was formed
The mountains of Nanyue have been rising and weathering again
The mountains have become even more majestic, and the landforms are in many different forms
The current landscape of Nanyue was formed 60 million years ago
