depositional cycle meaning in English

沉积旋回
沉积循环

Examples

  1. Erlian basin is a rift lacustrine basin developed on the hercynian geosyncline folded base in early cretaceous , is featured by simple sedimentary feature , depositional cycle , small lacustrine transgressive , dry climate , salinization lacustrine water and multi - and - near sources
    摘要二连盆地是在海西期地槽褶皱基底上发育起来的早白垩世断陷湖泊群,具有湖盆湖浸规模较小、气候条件干燥、湖水咸化、沉积旋回单一,多物源、近物源和粗碎屑等沉积特征,以及发育岩性地层油气藏为主的油气分布特点。
  2. The main conclusions are as follows ; firstly , under the influence of three phases of episodic activities , three two - order sequences is composed of three depositional cycles and three regional unconformities ; secondly , under the control of structure activities such as fault - block activities and the influence of three - order climate cycles and source recharge , lower cretaceous can be divided into six three - order sequence ; thirdly , because fault activities is weak and fault slope is gently , fan deltas exist in steep slopes in early and later stages and subaqueous fans exist and turbidite fans exist in troughs in middle stage
    主要的结论为:其一,受三期幕式活动影响,断陷形成了3个大的沉积旋回和3个区域不整合面,构成了下白垩统3个二级层序;其二,受断陷内翘倾和块断等构造活动的控制,以及三级气候旋回和物源供给因素的影响,下白垩统划分出6个三级层序;其三,在单断断陷湖盆中,湖泊阶段的早、晚期由于凹陷边界断层活动较弱,断面较缓,陡坡可以发育扇三角洲,在湖泊阶段的中期主要为水下扇砂砾岩体,并在洼槽区发育浊积扇。
  3. Depositional cycles on basin scale have been interpreted as the result of depositional response to tectonism such as episodic rifting , polyphasic compressive flexural subsidence and reversion , and differential subsidence of fault blocks ; while the formation of high frequency sequences was attributed to variation in lake level and sediment supply
    盆地规模的沉积旋回多是盆地幕式裂陷、多幕挤压挠曲沉降、多期构造反转、断块差异沉降等构造作用的沉积回应;高频层序单元的发育则主要与湖平面和沉积物供给量的变化有关。
