Scientists believe that in the past 2 million years, especially in the middle, late and Pleistocene epochs of hundreds of thousands of years, the terrain of western China has continued to rise, and the dry climate zone has been expanding. The loose rock masses deposited on the surface of these areas, such as sandstone, silty mudstone and conglomerate, are constantly weathered and eroded by the sun and wind, turning into a large amount of detrital material.
These large and small detritus materials disintegrated from the mountain and began to accumulate at the foot of the mountain. Under the action of the flood, it was washed away to the distant foothills, forming a large area of flood plain.
Whenever the dry season, under the action of strong winds, the fine sand and dust in the detrital material on the flood plain are blown into the sky, and the dust is blown to the area thousands of miles away, forming the Loess Plateau; And those fine sands are carried by the wind to the vicinity, forming a desert. The gravel with a relatively large particle size was left in place, forming the current Gobi desert landform.
The Gobi is a desert terrain covered with coarse sand and gravel on a layer of hard soil. According to the genesis of gravelly Gobi, it can be divided intoWeathered, water-formed, and wind-formedof the three.
The main cause of its formation is due to flood alluvium.
When a flood occurs, especially in a mountainous area, due to the gradual weakening of the flood energy, the following landform characteristics are formed in the flood impact area: large rocks are piled up at the nearest mountain pass, and the rocks become smaller in turn outside the mountain;
Then came a fist-sized finger-sized rock. Due to years of sunshine, rainforest and high winds, the edges and corners are gradually rounded and turned into what we call stone (scientific name gravel). In this way, the Gobi Desert was formed.
The finer sand and mud are alluvial and float farther away, forming a large desert farther away.
The Gobi is a type of desert. That is, a desert with gently undulating terrain and a large gravel cover. From Mongolian.
The Mongolian language calls the gravel desert the Gobi. The Gobi ground has been blown away by the wind because of the fine yarn, leaving gravel covering, so there is a difference between a gravel desert and a stony desert. The Mongols call it a desert area, which is full of sand and stones, with little water on the ground and few plants.

Desert?!The desert and the Gobi duel are two different kinds of things!
I can tell you responsibly: I live in the Gobi.
First of all, let me tell you what a desert is.
The surface of the desert is covered with a thick layer of fine sandy sand (have you ever been to the beach?). It's the same with the beach. It's just that the reasons for the formation are different, one is the long-term action of water, and the other is the long-term action of wind.
The surface of the desert changes and moves on its own, of course under the action of the wind :) because the sand runs with the wind. The sand dunes will move forward and change into different shapes.
It won't be like that in the Gobi. Because the surface of the Gobi is composed of loess and slightly larger sand and gravel. The ratio is about 1:
1.There is also more or less vegetation distributed on the Gobi Desert. When the wind blows, most of the dust blows, and when the wind is strong, there will be a landscape of sand and rocks, but the landform of the Gobi will not change.
In addition, it should be emphasized that the Gobi will turn into a desert under certain conditions!
Usually the edge of the Gobi is the desert. This is why some people mistake the desert for the Gobi. Therefore, we call on everyone to cherish water sources and save water! Take care of vegetation and strictly prohibit indiscriminate logging!
Because we're going to turn into a desert if we don't protect it here!
And if the desert continues to expand. Your home is about to become Gobi!

The Gobi is a desert terrain covered by coarse sand and gravel on the hard soil layer in the dry area, which is generally called the Gobi desert and the Gobi desert, which is translated into Mongolian as "a place where grass and trees are difficult to grow".
The climate on the Gobi is dry, the precipitation is small, and the grass and trees cannot grow, and the Gobi is distributed in the foothills of northern Inner Mongolia, the Tarim Basin and the Junggar Basin in Xinjiang. The Gobi Desert can only be used for irrigation by diverting water near water sources for agricultural and animal husbandry production.

In the current strange stone species, Gobi stone desert paint can be described as a lone show, he swept the strange stone market with a unique attitude, in this year's Taiyuan and Shijiazhuang stone exhibition in Xinjiang Inner Mongolia booth accounted for nearly half, which is more outstanding!
The following was taken at the Taiyuan Stone Exhibition.
<> the texture of the Gobi stone is hard, the color is heavy, all of them are weathered materials on the surface, and its large stones are very rare, most of them are delicate small stones, as a young but scarce stone, how do we play with him?
To play with the Gobi stone, in addition to having a certain understanding of the stone species, the most important thing is still your stone skills, whether a stone can shine depends to some extent on the perception of the stone appreciators, the following is an explanation with a personal collection of stones.
The following are individual and group collection stones.
Desert lacquer - Tyrannosaurus rex.
Gobi agate - bamboo shrimp.
Group of friends Sun Island Tibetan stones.
Looking at the above stones, do you have any experience?
Another Winnie the Pooh, can you wear it directly?
Maybe you are impatient, maybe you are salivating, but I do want to suggest that you need a pure heart to play with stones, and continuous learning and communication will improve your skills and achieve your stone edge! Pharaoh.

Gobi means barren beach, and the big Gobi is the big barren beach, which now refers to the big desert and the big barren beach.
A desert with gentle terrain and a ground covered with large gravel swaths. The Mongolian language calls the gravel desert the Gobi. All kinds of sediments in the erosion zone in the desert, such as flood deposits, alluvial deposits, glaciers, moraines and ice water deposits on the ice plain and detrital residues of bedrock after strong weathering, are blown away by strong wind, leaving coarse gravel, which covers the ground in pieces to form a gravel desert.
The Yumen area in Gansu Province in China is very typical. The gravel in the gravel desert is abrasively eroded by the sand carried by the wind, forming an angular wind prism stone, which has a brown iron and manganese oxide shell on the surface of the wind edge, which is called desert paint, which is formed by the precipitation of minerals dissolved in the evaporation of water in the gravel on the surface of the gravel.

Loading Gobi.
The Gobi Desert, also known as the Gobi Desert, is one of the world's largest desert and semi-desert regions, stretching across the vast expanse of Central Asia and across the vast expanses of Mongolia and China. Although Gobi means desert in Mongolian, in Chinese it sometimes refers to a desert area with rocks on the surface, as distinguished from a desert characterized by sand dunes.

The Gobi, also known as the Gobi Desert, is one of the world's largest desert and semi-desert regions, stretching across the vast expanse of Central Asia and spanning the vast spaces of Mongolia and China.
Gobi (Mongolian: in Mongolian it means desert, gravel desert, arid place, etc.).
The Chinese "Gobi" only refers to gravel, stony desert, semi-desert flat land.
-
The Gobi refers to the natural landscape of deserts, pebbles, and no water plants.
-
The Gobi Desert refers to a barren desert, or arid land.
When identifying Gobi agate rough, it can be identified by texture, hardness, and texture. Gobi agate rough is heavier than the fake one, and it will feel pressed in the hand, and the hardness is also higher than the fake one. The texture of the Gobi agate rough is very special because it has relatively small surface grains, and it is usually difficult to make this kind of graininess with fake ones. >>>More
