沉积旋回 [地质] sedimentary cycle
[地质] cycle of sedimentation
- 识别出不同地区的沉积旋回类型及其叠加方式。
Recognized sedimentary cycle style and superposition mode in different region. - 这也为沉积旋回的定量划分提供了一种新的思路。
All these researches provide a new clew for the quantitative classification of the cycle. - 盆地构造演化具多期次特点,火山作用与沉积作用频繁交替,形成了兴隆沟、蓝旗和义县三个火山沉积旋回。
It involves tectonic evolution of many times and frequent alternation of volcanism and sedimentation, forming Xinglonggou, Lanqi and Yixian volcanic sedimentary cycle.
