What is the formation of cobblestone

Cobblestone formation is a long process, which can be water erosion, but also the friction between each other. The pebble that you may be in the history of floods, mudslides caused (as is in the mountains) but the specific reason for doing there, geological structure, geographical environment, but also need to refer to the situation of the surrounding mountains. As for the really tall mountain not long tree may be the reason o the soil around the trees and caused by biological ties.

Pebbles are formed? About 100 million years ago in the Mesozoic, the role of movement in the crust, the magma emitting surface, rapid cooling of the magma would be the formation of granite. After thousands of years ago, due to the granite magma intrusion caused dislocation extrusion, resulting in a large number of smaller stones, those stones at the water's edge, over a long period of slow water erosion and their mutual rolling eventually leading to the present pebbles.

Pebble is a long time, evolving.
As the crustal movement of the vibration forces, weathering, and then after the impact of flash floods, water handling and repeated rolling friction between sand and gravel, and finally form a lovely rounded like pebbles. Rivers flowing through different geological structures, different rock mountain, through erosion, they form different components of the pebbles. Mountains of rock caving down as weathering, erosion in the river course, by the removal of water each rounded role and would like to form a pebble.


Another hard-hard stone, washed in the river, is also gradually become smooth, until the natural, smooth as eggs.
The formation of pebbles can be divided into two stages, first stage weathering of rocks, landslides stage; second stage is the rock in the river by river transport and the rounded stage.
Contain pebbles of gravel, which was caused by broken rock, only long-distance transport to edges and corners disappear, the formation of Park-shaped o oval stones (o pebbles, gravel), and then by cementation of rock known as the gravel.
Lapis colored sand stone pebbles stone Taihu Shi color: red cream, blue cream, wide red, coffee, Chinese Emperador, black white, cream thread, Hang Grey, yellow travertine, beige travertine, Emerald, Dandong Green, large flowers green, rice topaz, citrine, etc., and the rain the red, white marble, black jade, Jin Xiangyu, etc.

Originally thick is big rocks, but after millions of years of erosion and rain collide between each other, it becomes a block-clear beautiful pebble.
