新疆扎基斯坦地区土壤元素有机结合态测量法找铀试验研究

针对常规物化探方法对寻找砂岩型铀矿几乎无效这一现实，初步探讨了土壤元素有机结合态形成机理，并应用土壤有机结合态铀、钼测量法在新疆伊犁盆地南缘扎基斯坦地区进行了寻找地浸砂岩型铀矿试验。与全铀及210Po法测量结果对比表明，土壤有机结合态铀、钼异常能较好地反映埋深200 m以内的铀矿化，而全铀及210Po测量结果对深部砂岩型铀矿化几乎无任何显示。因此，土壤有机结合态铀、钼测量法有望成为地浸砂岩型铀矿找矿的有效方法。

STUDY ON EXPLORATION METHOD FOR URANIUM BY DETERMINATION OF ORGANICALLY FORMS OF ELEMENTS IN SOILS AT AJISITAN AREA , XINJIANG AUTONOMOUS REGION

This paper preliminarily discusses the formation mechanism of organically bound forms of elements in soils, and the test is conducted by applying the determinations of the forms of uranium and molybdenum in soils to prospecting in situ leachable sandstone type uranium deposits in Zajistan area in view of the fact that the traditional geophysical and geochemical explorations have almost no effect on prospecting deposits of this type. Compared with the total uranium and 210Po surveys, the determinations can indicate the deposits in depth of more than 200 m while the surveys cannot. Therefore, the determinations can hopefully become effective methods applied to exploring the deposits of this type.
