Over the past three decades, with the success in in-situ leach (ISL) mining of sandstone-type uranium deposits(SUD), the quantity, resources and production of SUD increased in China and the world, and it have leapt to the first in all types of uranium deposits. Based on the statistics for the latest database of IAEA, 1520 uranium deposits have been found worldwide, and 887 uranium deposits are sedimentary-type uranium deposits, accounting for 58% of the total number of uranium deposits; SUD have the largest number of 639, accounting for 71% of the sedimentary-type uranium deposits, accounting for 42% of the total number of uranium deposits in the world. The world has identified uranium resources (RAR+IR, <$130/kgU) 532.72×10 tU by 2011, of which sedimentary-type uranium deposits accounts for 44%, and sandstone-type uranium accounts for 32%. The two percentage will be 65% and 49% if not including Canada and Australia due to their monopolistic character. The amount of global uranium production increased by 64% from 2003 to 2013, 86% of which is from ISL mining. The amount of ISL production has leapt to the first since 2009, and the production from SUD accounts for about 56% of global total production in 2012. More than 350 uranium deposits and 272500 tU resources in China have been identified(OECD-NEA/IAEA, 2016), Sandstone-type uranium deposit accounts for 43% of the resources and has become China's the maximum amount of resources and resource potential in all types of uranium deposit. As can be seen from the above, most of the global uranium resources occur in sedimentary basins. 2 Universality and Division of Coexistence of Oil, Gas, Coals and Uranium in a Basin
