障壁岛—泻湖沉积体系特征与聚煤规律

Barrier Island-Lagoon Depositional System Characteristics and the Regularity of Coal Accumulation

叙述了障壁岛—泻湖体系的内部构成、成因相及各种沉积体发育特点,障壁岛一泻湖体系中砂体的组合关系、空间分布格局与海平面升降、沉积物类型、水动力强度的相互关系,指出了障壁海岸沉积体系的主要聚煤环境、潮坪沉积体系的聚煤特点及富煤环境形成与分布规律。

This paper describes the barrier island-lagoon system of the internal components, the origin of the phase and various kinds of sedimentary bodies development characteristics, the relationship between sand body combination relations, space distribution pattern and sea-level fluctuation, sediment types, water power of the strength in barrier island lagoon system, and points out that the barrier coast sedimentary system＇s main coal-bearing environment, tidal flat sedimentary system coal-bearing characteristics and rich coal environment formation and distribution.
