摘　　要：通过用电子显微镜对新疆库车盆地第三系含钾岩屑进行形貌及能谱元素成分分析研究,发现该盆地2400～3600m间累计含钾岩层厚度约100m。分上下两大含钾类型层,下层主要为硫酸盐钾芒硝类型,上层为钾石盐(光卤石)类型。It is found that the accumulative potash terrane thickness from 2400 m to 3600 m of the basin is about 100m by the composition analysis study of extrinsic feature and energy spectrum element on the tertiary debris with potash in Xinjiang Kuche basin with electron microscope. It is two types of terrane with potash, sulphate mirabilite type on the sublayer and potash rock salt（carnallite）type on the superlayer.
