摘    要:本文从研究伊犁盆地不同地段含煤系地层岩性变化特征入手,提出冲积扇快速入湖的扇三角洲沉积相模式,并讨论了4个沉积亚相,即冲积扇、扇前辫状河、滨湖三角洲、湖沼相的沉积相特征及其空间展布规律,研究了含煤系沉积相与层间氧化带砂岩型铀矿的成矿关系,指出了滨湖三角洲相砂体是寻找层间氧化带砂岩型铀矿的主要部位。

关 键 词:含煤系,沉积相特征,砂岩型铀矿,滨湖三角洲相砂体

Abstract:Starting with the study on the stratigraphic and lithologic characteristics of the coalbearing series at different places in Yili Basin, this paper proposes a fan-delta sedimentarymodel, and discusses the sedimentary features and spatial distribution regularities of its foursubfacies (namely, alluvial fan, braided stream, lakeshore delta, lacustrine and marsh factes ).Then, the relationship between sedimentary factes of the coal-bearing series and the formation of sandstone uranium minerlizations of interlayered oxidation zone type is investigated,and the lakeshore delta sandstone body is pointed out to be the major target for the prospectlug of sandstone uranium deposit of interlayered oxidation zone type.
Keywords:Coal-bearing series  Characteristics of sedimentary factes  Sandstone type uranium deposit  Sandstone body of lakeshore delta factes
