<br><br>In the November 30 issue of "Science Bulletin" Vol. 54 22 on the Guangzhou Chen Ming of the Chinese Academy of Sciences, who published "Xiuyan meteorite crater confirmed,hogan scarpe interactive uomo," confirms (Liaoning) Xiuyan found China's first meteorite impact craters,chaussure zanotti, the study fills our territory such unique geological formations acting blank.<br><br><br><br><br><br>Recently,tiffany italia, reporters rushed to the Liaoning Xiuyan Manchu Autonomous County Town of Cologne Su village,felpa adidas, explore the 1.8 km diameter crater 150 meters deep secret.<br><br><br><br><br><br>Has shown signs of pit<br><br><br><br><br><br>Giant ring lying mountains<br><br><br><br><br><br>Cologne entered the village,giubbotti moncler, we will be in front of the "pit" of the shock. In the "pit" entrance, on both sides of the ridge suddenly broken, only to leave people a narrow dirt road.<br><br><br><br><br><br>Climb to the top, the reporter was surprised to find, "pit" with a standard Zhengyuan actually almost the same, plus surrounded by mountains, like a giant ring lying quietly in the mountains.<br><br><br><br><br><br>Four 周山岭 climb down from the crater watching the entire pit was a bowl shape. Crater diameter of about 2000 meters, the pit depth of about 150 meters,louboutin pigalle, according to the villagers, an existing group of villagers,hermes bracciali, more than 60 families living here. Due to the shape of a circle around the mountain surround,negozi woolrich bologna, so the villagers set to "bandy" for the name of the village.<br><br><br><br><br><br>Hang strange<br><br><br><br><br><br>Well water can burn the oil slick in Black<br><br><br><br><br><br>"Pit" and generations living here,louboutin chaussures soldes, because not very convenient transportation, where the villagers rely on the mountain sericulture and farming to sustain life. Because of this,rayban, Azeri circle of life is not rich, even as some still unexplained natural phenomena villagers complain incessantly. First, where the water and outside different. Many people in the village to take up water wells are floating layer of oil, simply can not drink.<br><br><br><br><br><br>In addition to a layer of oil floating in the water, the "circle" There are strange things, that is buried underground where a black soil, dug up after dry surface with white cream, throw fire can burn.<br><br><br><br><br><br>3-year survey<br><br><br><br><br><br>OK Xiuyan crater<br><br><br><br><br><br>As early as between 1982-2004,dior occhiali da sole, a number of research units have to Xiuyan field trips, want to verify the crater of speculation, but for various reasons, and ultimately failed to identify.<br><br><br><br><br><br>In early 2007,armani lunette de vue, Chinese Academy of Sciences Guangzhou Institute of Geochemistry, Dr. Chen Ming rate researchers in Xiuyan expand research, and initially this unique geographical landscape named "Xiuyan pit." Researchers in the study of the first year,louboutin online france, that capture the surface rocks in the pit area to the physical changes impact shock wave traces left for later study provides critical scientific evidence, clear way to explore technology.<br><br><br><br><br><br>March 20 this year,chaussures louboutin, Chen Ming led the team once again came to "Xiuyan pit", for a period of more than five months of drilling survey work,louboutin chaussures soldes, reveals the geological structure of the deep pit body and get valuable deep rock samples. Rock sample batches were sent to Guangzhou,peuterey online, the researchers found a strong impact lead to the meteorite target rock deformation, evidence of shock metamorphism series fragmentation and partial melting as well as rocks and minerals occurrence, from a scientific point of view and ultimately proved that the pit is formed by meteorite impact,nike sito ufficiale, Xiuyan meteorite impact craters also became the first confirmed scientific craters.<br><br><br><br><br><br>The results showed that the Rock Xiuyan meteorite crater 20 million years ago formed the Early Proterozoic metamorphic rocks. Through the analysis of radioisotopes pit substance, initially identified meteorite impact event occurred 50,000 years ago. After the formation of meteorite impact craters,bvlgari bracelets, pit water formed small lakes and lake sediments deposited hundreds of meters thick. Around 39,porsche design lunette de soleil,000 years ago, the low-lying "Xiuyan pit" east formed a gap, the water outflow and erosion of mountains,converse costa rica, lakes and finally disappeared, evolved into today saw a bowl-shaped depressions.<br><br><br><br><br><br>(According to "Liaoning Daily" reported)<br><br><br><br>
