In evolution process of all geologicalhistory, uranium gathers without interruption in upper crust. Urani-um mineralization is closely realted with evolution characteristics of thecontinent crust.1. It was not until the continent crust evolved to certain maturedegree that uranium began metallization. The oldest uranium depositon the earth occurred in the Delanshiwa （Kapuwaer） district,展开更多

Africa misappropriates time as it does to other resources, such as minerals. With this tradition, everything on the continent is always running behind schedule.

As a significant national strategy for China, the emphasis is on the construction of roads and achieving economic agglomeration and radiation through the construction of traffic axes. Using published literature and data analyses, this paper studied current traffic patterns between China and other regions within the SREB from the perspective of rail, ocean and air transportation. With regard to existing problems and development prospects of these three types of transportation, we propose construction modes for the traffic economic belt across continental plates and that future construction within the SREB should consider key cities as joints and arterial traffic lines as development axes, promote connecting of joints by lines, advance deep construction through joints and axes, connect lines into net, and develop informationalized traffic economic belt on the basis of trans-regional cooperation.展开更多
