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。基本的预测有准则为构造准则 ,岩性准则 ,地球化学准则。总结并提出了铀成矿评价的三个必要条件 :透水疏松砂层 ,铀源 ,地球化学栅。 1∶2 0万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有利层位之一。
The deep origin of ore forming is a new theory for prospcting in situ leachable sandstone type uranium.Tectonics,lithologics,geochemistry are basic forecasting criteria.Previous unconsolidated sand,source of uranium and geochemical barrier are three essential condition for forming uranium deposit.Metallogenic enviroment and prospective region are found.Tertiary system is prospctive layer for prospcting in situ leachable sandstone type uranium in the south of Song Liao Basin.
