Quaternary glaciers, very far away from us, about a million years ago or so to the Ten thousand years ago, between the million years, but also human beings appear, the long stage of evolution. Quaternary glacier from us again very close, in the Helan Mountain Pass have found many relics of the Quaternary glacier, and we see it, and massage to get it, we have been living in human beings, even among its influence. In time, it is very far away from us; in space, it was close. It is this far from a recent cause us many suppose.
Iceberg scratches and rock art background to about 180 million years ago, a small dinosaur was born, it will, and it, like all parents proudly watching this world, because they are at the top of the world's food chain, perhaps, they think they are the master of the earth.
Ultimately, however, dinosaurs disappeared, the human being as the top of the food chain.
All these are created by glaciers.
Helan Mountain rock formation of large, imposing extraordinary mountain valley and mountains piled rocks, all these are also related with the glacier. The Helan Mountain rock painting rich and dense, which also concerned with the glacier ... ...
Helan I rock paintings discovered glacial scratches, people full of curiosity, imagination.
With these questions, in the Helan mouth rock art under the guidance of director of management, we detect a geologist, Mr. Zhou Kunshu recently identified three significant relics of ancient glacial rock scratches. This three glaciers are located on a smooth surface scratches, a number of parallel lines in the same direction. In accordance with the geological scholars say, it is with the valley glacier advance, the sandstone formation of the slow movement. Which at an altitude of 1320 meters, north latitude 30 degrees 45 minutes east longitude 106 ° 0.1 points a, that is, the south side of the mountain like a rock art engraved faces of the people there are obvious scratches and rock art images intertwined, from the color point of view, rub marks and nicks Jun Cheng dark brown rock paintings. Even with 15 times larger micro-sight observation, is also still see scratches in rock art and rock paintings scored the rock surface color is consistent. Some scratches can be seen with consistency.
Scratches are very obvious, but if it is not pointing geological experts, most people will not link it with ice. This is also the Helan Mountain rock paintings dating has not been solved, there is no exact reason why the light of the geological age. In fact, as early as in 1983, our region has many geological workers in the Helan Mountain Pass found, including scratches, ice Hom, cirque, Quaternary glacial boulder and other relics, mainly concentrated in the vicinity of Soviet yukou. Scratches on the glaciers have been different times of the controversy, there is no unified understanding, but I do not know what is the reason why no mention of the Helan mouth glacial scratches. At that time, Ningxia Helan Mountain rock art research is still in its infancy, for the relationship between the ancient geological features and rock art there is not enough knowledge to break the ice between scratches and rock paintings have been in people's sight. Shuidonggou last year during the commemoration of the 80th anniversary of the famous geologist Kun-tert-glacial rock art tours in the Helan mouth, the chance discovery of many glaciers in this scratches.
Glacial scratches and rock paintings to break the relationship between pairs of Helan Mountain rock paintings dating itself have much impact, the most important is the painting of the geological background will have a more explicit reference to the mountain because of Helan Mountain sandstone, its hardness greater in the Stone Age times it is difficult to stay on the surface nicks, but rock paintings portray the rock surface, is one centimeter thick "stone skin", this layer of stone skin is not inherent in the mountain, is outside low temperature, high pressure results, which is likely related with the external force of glaciers. This layer "hardness," a low, easy to portray rock art, but this is only a preliminary to conclude that further conclusions to wait for test results come out to say.
