  1. 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

    主要的結論為:其一,受三期幕式活動影響,斷陷形成了3個大的沉積旋迴和3個區域不整合面,構成了下白堊統3個二級層序;其二,受斷陷內翹傾和塊斷等構造活動的控制,以及三級氣候旋迴和物源供給因素的影響,下白堊統劃分出6個三級層序;其三,在單斷斷陷湖盆中,湖泊階段的早、晚期由於凹陷邊界斷層活動較弱,斷面較緩,陡坡可以發育扇三角洲,在湖泊階段的中期主要為水下扇砂礫巖體,並在窪槽區發育濁積扇。
