| 摘 要： | 库车坳陷中段盐层广泛分布,可细分为盐岩层、膏泥岩层、膏盐层等不同沉积端元。在沉积载荷、浮力及区域构造挤压应力作用下,盐层发生塑性流动,盐上构造层、盐下构造层也发生变形,形成了盐下构造层、盐层、盐上构造层三位一体的复合盐相关构造样式。本文从构造变形差异分析入手,结合盐层沉积特征、基底古地貌特征、盐上构造层沉积差异,运用生长地层和不整合分析方法认为库车坳陷中段盐相关构造样式的形成主要受控于盐层性质、基底特征、构造应力和沉积差异负载。

| Abstract: | The Paleogene salt bed of Kumugeliemu Formation distributes widely in the central segment of Kuqa depression.It is composed of rock salt,creaming mudstone,creaming rock salt.The salt bed began to flow because of the sedimentary loading,buoyance and compressive stress,and then the structural layers both the top of and underside of the evaporite bed commence to deform.Thus,the triune compound structure styles related to salt of the supersalt layer,salt layer and subsalt layer came into being.By analyzing the ... |
