摘　　要：研究表明,在伊犁盆地南缘产出一条东西长达近百千米的铀及伴生元素成矿带,在我国境内依次产出有509、510、511、513及512铀矿床,此外还有多个铀矿化异常点.其中511、513、512等矿床为可地浸砂岩型铀矿床,受层间氧化带控制非常明显.从已知矿床的成矿环境和特征出发,阐述了伊犁盆地南缘层间氧化带的空间分布及控矿规律,通过不同层位的层间氧化带含矿性对比及同一层位不同地段的层间氧化带含矿性对比,总结出了伊犁盆地南缘含铀矿层间氧化带特征.A mineralization zone of uranium and associated elements, 2-5 km away from the piedmont, trending E-W about 100km, occurs at the southern margin of Ili basin. Uranium deposits occur at Daladi (509), Menqigur (510), Zajistan (511), Ukurqi (513) and Kujiertai (512), with lots of uranium occurrences additionally. The uranium deposits 511, 513 and 512 belong to in-situ leachable sandstone-type uranium, strictly controlled by interlayer oxidization zones. The area distribution and ore-controlling regularity of interlayer oxidization zones at the southern margin of Ili basin are described based on metallogenic setting and characteristics of the known deposits. The characteristics of interlayer oxidization zones are summarized through comparison of ore-bearing potential of interlayer oxidization zones from different horizons or same horizons but different sections.
