Uranium Exploration 

Uranium exploration in China started in the 1950s. The total drilling completed thus far amounts to more than 40 million meters. High-precision aerial radiological surveys of nearly 1/3 of the country's land area have been completed, and more than 370 uranium deposits identified. The latest evaluation of potential uranium resources across the country predicts a total of more than 2.8 million tons of uranium. Since the mid-1990s, the prospecting for uranium has shifted to sandstone-type uranium deposits and important discoveries have been made in sedimentary basins in northern China, doubling the identified reserves of uranium resources. A number of large or extra-large uranium deposits have been found in Yili, Ordos, Erlian, Songliao, Turpan-Hami and Bayingebi basins. The northeastern part of Ordos Basin is found to be home to China's first known 100,000-ton uranium deposit. Uranium resources have been discovered in 23 provinces (autonomous regions) in China, of which the Inner Mongolia Autonomous Region, Jiangxi Province and Xinjiang Uyghur Autonomous Region have the most abundant deposits. 

鈾礦地質(zhì)勘查

中國鈾礦地質(zhì)勘查工作始于 20世紀(jì) 50年代，至今已累計(jì)投入鉆探工作量 4000多萬米，完成了近 1/3國土面積的高精度航空放射性調(diào)查，查明 370余個(gè)鈾礦床。在新一輪全國鈾礦資源潛力評(píng)價(jià)中，預(yù)測(cè)鈾礦資源潛力超過 280萬噸，顯示出巨大的找礦潛力。 20世紀(jì) 90年代中期以來，中國鈾礦找礦重點(diǎn)轉(zhuǎn)向砂巖型鈾礦，并在北方沉積盆地取得了重要突破，實(shí)現(xiàn)了新增鈾礦資源儲(chǔ)量翻番。伊犁、鄂爾多斯、二連、松遼、吐哈、巴音戈壁等盆地探明了一批大型、特大型鈾礦床，其中鄂爾多斯盆地東北部已成為中國首個(gè)十萬噸級(jí)鈾礦資源大基地。目前，中國 23個(gè)?。▍^(qū)）發(fā)現(xiàn)有鈾礦資源，以內(nèi)蒙古、江西和新疆鈾資源最為豐富。
