【摘要】 可容空间概念是层序地层学理论体系中的一个重要组成部分。可容空间受到层序地层学理论中的构造沉降、海平面升降、沉积物供给和气候等4大控制要素的影响和控制,其中由不同构造背景所控制的盆地的演化特点对可容空间的性质和变化具有重要意义。在盆地内部可容空间发育具有不均衡性,其分析方法主要有构造沉降曲线和海平面升降曲线叠加法和断层活动计算法等。更多还原

【Abstract】 Accommodation concept is a main component of the sequence stratigraphic theory.The evolution of accommodation is controlled by sea level changes,tectonic subsidence,deposit accumulation and climatic element.Above all,tectonic subsidence is a key factor controlling the formation and evolution of accommodation.The formation and evolution of different stratigraphic units of different accommodation are dominantly controlled by different scales of basin characters.Based on the characteristics of tectonic subsidence and tectonic movement models,the basic patterns of accommodation and their depositional characteristics have been discussed,and some imperfect fields of the accommodation concept are pointed out.更多还原
