文章认为铀成矿作用发生在这些次级构造单元形成之后,且具有找矿前景的是南部向斜带水西沟群第Ⅱ、Ⅲ、Ⅴ、Ⅶ旋回砂体和北部单斜带水西沟群第Ⅰ、Ⅱ、Ⅲ、Ⅴ旋回砂体及小泉沟群砂体。从容矿层位连续性、分布面积、砂体特征及层间氧化带发育特征等成矿条件看,北部单斜带铀成矿条件和找矿前景均优于南部向斜带。

The Chepaizi-Mosuowan paleo- uplift of N-E extending was shaped with the uplift ing of hinterland of Junggar basin during the Mid-Late Jurassic, which changed the structural framework of monoclinal hinterland of the basin, forming quite a few litho-stratigraphic traps of Mid-Upper Jurassic distributed along both sides of Chemo uplift .

格状沙丘的形成必须具备两个方向风夹角成90-135°、输沙能之比为2:1至4:1的双向低能风况条件和风成沙连续覆盖且主沙丘或主梁具有较大规模等沙源供应条件。

Tectonic subsidence play dominant role in their geometric shapes, basin fillings, sequence evolution and sediment distribution in the Wushi Sag. Outline of the sequences are in shape of box-wedge or sheet-wedge and boundaries of sequences are varied from bilateral fault to monoclinal fault overlap, so that the sequences show distinct semigrabens which overlay in different ways. Seven sequences were formed in different stage of tectonic evolution. The sequence of SQ1 formed in initial rift stage and deposited alluvial sequence. Sequences SQ2-SQ4 developed in intense rift stage and sediment lacustrine sequence. Sequences SQ5-SQ7 formed in late period of rift before thermal subsidence and deposit mere and delta sediment. The place adjacent to the synsedimentary fault is the subsidence center and depocenter; meanwhile, controlling fracture migrates in horizontal made subsidence and sedimentary center of the sag changed.

构造沉降是控制层序几何形态,充填叠置方式、演化及沉积体系分布的最重要因素:凹陷由多个半地堑在不同层序发育时期以不同方式叠置联结而成;受断层控制,层序外部形态有箱状-楔形、楔形-席状披覆型,边界终止方式有双断终止型、单断终止超覆型;不同构造演化阶段层序内部充填的沉积体系各具特征,初始断陷阶段的SQ1沉积冲积层序,强烈断陷阶段的SQ2-SQ4充填湖相层序,晚期断陷阶段SQ5-SQ7内部充填浅湖和河流三角洲沉积;同沉积断层陡坡带沉降迅速、可容纳空间快速增长,是凹陷的沉积和沉降中心,断陷期主控断裂活动时间和空间的变化导致了凹陷沉积和沉降中心的迁移。
