深源成矿论是可地浸砂岩型铀矿地质找矿的一种新思路 ,在松辽盆地南部铀矿勘查中得到了较好的应用 .基本的预测准则为构造准则、岩性准则、地球化学准则 .总结并提出了铀成矿评价的 3个必要条件 :透水疏松砂层 ,物源补给区 ,地球化学障 1∶ 2 0 0 0 0 0带钻区调已在该区找到有利的成矿环境和成矿远景区 ,已查明上第三系是本区形成可地浸砂岩型铀矿最有利层位 .
Deep source mineralization is a new idea of geological prospecting of leachable sandstone-type uranium deposits, and has been well applied in uranium exploration in southern Songliao Basin.The basic prediction criteria are tectonic criteria, lithological criteria, Geochemistry criteria. Three requirements for the uranium mineralization evaluation are summarized and put forward: Permeable Loose Sandstone, Source Replenishment Area, Geochemical Barrier 1: 20000 0 0 The metallogenic environment and the prospecting area have identified that the Upper Tertiary is the most favorable horizon for the formation of leachable sandstone-type uranium deposits in this area.
