Retreat of trench may lead to back-arc extension. The Pacific plate subducts at low angle beneath the Eurasia plate, tomographic results indicate that the subducted Pacific slab does not penetrate the 670 km discontinuity, instead, it is lying flat above the interface. The flattening occurred about 28 Ma ago. Geo- dynamic computation suggests: when the frontier of the subducted slab reaches the phase boundary of lower and upper mantle, it may be hindered and turn flat lying above the boundary, facilitates the retreat of trench and back-arc extension. Volcanism in northeastern China is likely a product of such retreat of subduction, far field back-arc extension, and melting due to reduce of pressure while mantle upwelling.展开更多

China, known as the "Kingdom of Bicycles", has the largest output and export volume of whole bikes, but the industry has been in difficulties in recent years. The blind import of international capital is the main reason for the decline of the bicycle industry in the country. In the mid 1980s, cheap labor and optimistic market forecasts attracted international capital to China’s bicycle indus-展开更多
