区域不整合 meaning in Chinese
interregional unconformity
interregionalunconformity
regionalunconformity
Examples
- Regarded regional unconformity , transformation basement of tectonic regime , incised water channels , discontinuous surface of sidementary facies and exposed surface of lowstand as boundary of sequence , the palaeozoic in the researched area can be divided into three supersequence and fourteen sequence
以区域不整合面、构造体制转换面、水道下切谷、沉积相突变面及低水位期暴露面作为层序界面，将研究区古生界划分为3个层序组和14个层序。 - 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。
