| 摘 要： | 从中小型陆相红色盆地沉积的基本组成和结构特征入手，重点就区调填图中存在的问题及区调方法、内容等进行分析与探讨。红层区冲积扇体是一种特殊类型的沉积地质体，为揭示其时空分布规律，提出被某些特征面所分隔、同期洪积事件形成的各冲积扇体组成与“组”相当的基本填图单位；在扇体内进一步划分岩性段与扇根、扇中、扇缘岩相带。

| Abstract: | The author has studied the fundamental composition and structure of sediments in intermediate and small sized red basins. On the basis of the study, the paper mainly discusses the problems in regional mapping and methods and contents of regional surveys. The author considers that alluvial fans in areas of red beds are a special type of sedimentary strata body. In order to reveal their temporal spatial distribution pattern, it is proposed that a basic mapping unit equivalent to the “formation” may be formed by various alluvial fans separated by some characteristic boundaries and generated by a synchronous diluvial event and that a fan may be further divided into lithological intervals and fan root, fan center and fan fringe faices zones. |
