Turpan - Hami Basin "cool memories"

People who have been to Turpan, the deepest feelings is above 40 degrees Celsius heat. There has been a "Flaming" it?

 2012, the CAS Nanjing Institute of Geology and Paleontology researcher Wang,http://www.wdlh.com.cn/home.php?mod=space&uid=15756,air max one rouge et blanche air max 3, Ph.D. Wan Ming Lai,hollister stockists uk cheap hollister hoodies,http://www.greek-life.org/index.php/forum/greek-life/174504-reporter-intern-provided-for-the-chi-wan-qin-wang#174587, Missouri University of Science and Technology Professor Professor Yang Wan et al, in Xinjiang discovered a "Steinmann septate pith pine" fossil, after more than two years research,outlet hogan civitanova franchising scarpe hogan, they restored the 255 million years ago, Turpan - Hami Basin "cool memories",http://www.newxue.net/forum.php?mod=viewthread&tid=148859, where warm and humid, the annual average temperature of 12 to 14 degrees Celsius, the average annual rainfall of 900 to 1240 mm. Recent research results published in the internationally renowned geoscience journal "paleogeography,air max one en solde, paleoclimate, paleoecology" on.

Tree "tree" rings obvious

"This is our research petrified wood." Wang's computer has a chart, graph petrified wood fossil, about 15 cm in diameter.

"It actually is a tree of life 255 million years ago in the pine, now extinct and it should be very long,chaussure nike pas cher homme nike tn enfant, we found only a part of it." Wang said their study is a fossil conifers,http://www.bbs0556.com/home.php?mod=space&uid=159525, how old it lived, how it was dead? These are not known. To be sure, the tree of life in the Permian mass extinction 10 million years before, in the end-Permian mass extinction, which belongs to "disappear" category.

Wang They put the tree named "Steinmann septate pith pine," to commemorate the ancient Chinese study of botany and continental strata pioneer Adams Xingjian Academy of Sciences. They fossils slices, careful study under the microscope. Time has passed 255 million years, but the tree is still intact xylem cells, the cells above the hole, big and small, in the middle there is one small interval ...... "This tree's growth rings is not obvious, the fossils Cell size is gradual. "Wan Lai Ming said, with a microscope, they also found a tree" lifetime "situation is not good, it was mites Kenshi, the body is full of mites droppings.

255 million years ago, Turpan annual average temperature is around 13 ℃

. "Plant is climate change 'thermometer', then paleoclimate, paleoenvironment how,air jordan soldes nike air max bw, through plant can interpret it,nike air jordan noir jordan 11 noir," Wang Jun,http://www.msnightlife.com/activity/p/509420/, for the Turpan - Hami Basin paleoclimate, Professor Yang Wan has been studied for more than 10 years,http://zn50.com/home.php?mod=space&uid=185973, Previously, scientists have studied the lithosphere surrounding plants, soil, suggesting a general situation where the ancient climate, but it has been a lack of botanical evidence.

In fact, the plants on the climate,boutique moncler france moncler taille, more sensitive to carbon dioxide, rain,http://www.iwwss.cn/home.php?mod=space&uid=3092, high temperature, when the trees grow relatively fast,hogan scontatissime scarpe hogan outlet on line, petrified wood in the cell will be relatively large; rather cold and relatively dry, the trees will grow more slowly, petrified wood cells will be more dense.

Through the "Steinmann septate pith pine" fossil studies, Wan Ming ceremony to restore the 255 million years ago, Turpan climate. . "There is not a natural Huoyanshan, 255 million years ago, there is very cool, moist," Wan Ming Lai said,http://blissphotographyandboutique.com/blog/?p=417176,hogan scarpe femminili hogan 2013 outlet, then, Turpan - Hami basin is about 50 degrees north latitude, and the annual average temperature at 12-14 ℃, annual average 900-1240 mm rainfall.

And today's Turpan Basin climate causes, Wan Ming Lai believes that may appear relevant and Bogda Mountains. Dating back about 250 million years ago, because of the Tarim and Junggar plate - Turpan micro-plate collision, plus the Cenozoic plate motion collision, extrusion, forming a Bogda Mountains. "The emergence of the Bogda Mountains,hogan vendita hogan store online, affecting the atmospheric circulation, blocking the rain the clouds, causing drought Turpan Basin today."

For this study, Wang Jun, their ultimate goal is to explore the period dating back 300 million years to 250 million years on Earth suddenly thriving biodiversity extinction reasons. "Steinmann septate pith pine is before the end-Permian mass extinction creatures disappear. At that time, 95 percent of the world's marine life and 75 percent of terrestrial organisms in the mysterious disappearance of 'short-term' inside."
