Massive craters
the construction team workers are digging the Bottom of the work
Recently, Yanqing County in Beijing, the Heung Chang Dazhuangke the white side of the road Red Dragon, pit. When the
researcher at the Institute of Chinese Academy of Geological Sciences with Han Lin, the Chinese regional geology and mineralization Geological Society Research Fellow, Xu came to the rain Chapter Dazhuangke Longtan Township, White, field research, and the causes and the White Dragon's engaged in a fierce debate .

Township, Yanqing County Public Dazhuangke members of Wu Ting was introduced, a large puddle in the mysterious town Cheong Dazhuangke Red Road and the intersection of Lotus Road White Dragon under the bridge, surrounded by lush vegetation, a stream flowing from the bottom, no different from ordinary valley. In the 80s of last century, when rich white Longtan water,
true religion store, the deepest place there is 3 meters. Persistent drought in recent years,
true religion skinny jeans, only 1 meter deep water. July 2010,
true religion sale, they plan on Red Road, both sides of the road landscape Chang beautification treatment, so they want to clean up the White Dragon Pool, surrounded by a stone on base, build a water landscape. However, in the clean-up found that only a few meters deep puddles originally, the result that more digging deeper, and later transferred to a large excavator to dig more than a month. Such as the large pit full nudity, it was surprised to find, like a circle Shitan jar, set in huge granite center, open oval, smooth walls, bare hands can not climb. After cleaning, the measured result, the maximum port width is 20 meters deep, 18 meters, all composed of hard granite.
It is near the village elders, in their childhood, the deep pit of water, to prevent children from around the adults, so far no one has seen the true face of giant pit.
>>> guess
nature created by
the reasons for the formation of giant crater, it is also different opinions, there was speculation that meteorite hit the pit, there was speculation that the impact of the formation of water, and still others dug manually. Wu Ting was that man-made cut is unlikely. Although some of the local masons, but site investigation by experts found that the giant hole from top to bottom, very smooth, no trace of processing.
Chinese Academy of Geological Sciences and Technology Department experts said, he speculated that the formation of white Longtan giant pit pit, stone pit will be worn edges and corners,
levis jean, a certain smoothness. years ago, Moulin
Korea with the forest known as the He believes that because of the Ice Age White Dragon traction and the formation of intense, that white is more than 200 million years ago, Longtan early Quaternary glacial melt water erosion results, it can be called Moulin.
Han Lin identified with, the large granite stone pit, learning called above the glaciers. glacier melting process, the water straight down the impact of the formation of giant rock pit. The reason is called the Moulin is because of its small mouth and the big belly, exactly like in ancient China for Tsuishine the mortar. look in the Beijing area long Lingzhen Po Kawamura, Huairou glass temple area have been found by the tens of centimeters to two or three meters deep Moulin, but so deep Moulin Yanqing was the first time. It is worth mentioning that in the bottom of this giant Moulin, also stands a very strange 6 meters tall The modern product
while another expert Zhang Yu Xu believes that the White Dragon Pool is located in the middle of mountain and valley, that it is unlikely that ancient product. Because if the product of the ancient, the one which is bound to be eroded away; Secondly, even if the pot hole had the privilege of reservations,
cheap true religion, it is difficult so happened, to the 20th century, only to be filled in 60 years half of the depth.
Zhang Yu Xu, according to the geological characteristics of white Longtan speculated that the potholes formed by erosion due to floods - one pot turning point in the valley and the narrow place, there is the formation of high-speed rotating vortex conditions. The second is the formation of potholes may have experienced several major floods. Third, we can see from the tornado, has a strong high-speed rotation of the fluid handling capacity of the human tornado can roll into the sky, strong winds and even the ordinary can be Feishazoudan. Therefore, the 20th century, the white 60's last big flood Longtan is empty (or partially empty) to form potholes (and may again deepen,
true religion online, intensify pot hole) after he was late or later the smaller flood flood boulder filled valley formed. Fourth, the integrity of potholes now cleared may be repeated several times under the flood erosion from the vortex.
