自六十年代初期在新疆库车盆地开展钾盐找矿工作以来,该区下第三系的巨厚石盐岩层就被视为重点研究对象,成为找钾的直接目的层。库车盆地有一些盐丘分布,构造比较复杂。这是巨厚的盐层在压应力作用下,因其塑性变形而造成上拱,刺穿和外流等特殊的构造形式,其结果使盐层产状变动剧烈,伴随有密集的断裂和复杂的褶皱。该区出露地表的盐层,在宏观岩性上有一定相似性,其层理不清晰,夹层少,古生物化石稀少,缺乏对比标志。强烈的后期溶蚀作用又使得盐层的面目全非。埋藏于地下的盐 Since the early 1960s, when potash prospecting was carried out in the Kuqa Basin, Xinjiang, the formation of huge thick salt rock formations in the Tertiary in the area has been regarded as a key research object and has become the direct target for potassium seeking. There are some salt domes in the Kuqa Basin, with relatively complicated structures. This is a very thick salt layer under compressive stress, because of its plastic deformation caused by the arch, piercing and outflow of special structures, the result of the dramatic changes in salt production, accompanied by intensive fracture and complex Folds. The exposed salt strata in the area have some similarities in macro lithology. Their stratigraphy is not clear, the interlayer is thin, paleontological fossils are scarce, and there is no contrast mark. Strong post-erosion effect makes the salt beyond recognition.
