| 摘 要： | 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1:200000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.

| Abstract: | The deep origin of ore forming is a new theory for prospcting in situ leachable sandstone type uranium Tectonics,lithology and geochemistry are the basic forecasting criteria Previous unconsolidated sand, source area and geochemical barrier are three essential conditions for the forming of uranium deposits Favorable metallogenic enviroment and potential region have been found The Tertiary system is a promising layer for prospecting in situ leachable sandstone type uranium in the south of Song Liao Basin |

| Keywords: | deep origin of ore forming forecasting criteria sandstone type uranium prospective region |
