| 摘 要： | 本文通过对河道和河谷两个不同地貌单元特征的界定 ,澄清铀矿地质领域中对古河道型砂岩铀矿床与古河谷型砂岩铀矿床概念上的混淆。同时就河道与河谷对基准面变化的响应及充填序列特征作了探讨 ,为确定古河道在平面上的展布提供依据。 |
| 关 键 词： | 河道 河谷 铀矿床 充填特征 基准面 |

| Abstract: | By discriminating the characteristics of two different geomorphological elements-stream channel and stream valley, this paper tries to clear up the concept of paleochannel sandstone type uranium deposit and paleovalley sandstone type uranium deposit in the field of uranium geology. Moreover, the author also discusses the response of the stream channel and stream valley to the variation of erosional basis and characteristics of depositional sequence. The above mentioned provides help for the determination of the distribution of paleochannels on the plan. |
| Keywords: | Stream channel Stream valley Uranium deposit Depositional characteristics Erosional basis |
