steep fault
解釋
陡角斷層-
The frontal structure of longmenshan in the west of sichuan is very complex, showing intense structure deformation in overthrust belt, high structure amplitude, steep stratigraphic dip, developed fault blocks, complex seismic wave field, frequent change of lateral velocity, and poor image of post - stack time migration processing
摘要川西龍門山前緣構造非常復雜，逆掩推覆構造帶構造形變強烈，構造幅度大，地層傾角陡，斷塊發育，地震波場復雜，速度橫向變化大，常規疊后時間偏移處理成像效果較差。 -
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。 -
We predicated three favorable zones : the excellent play is at the downside of the east terrace - fault slope, the good play is distributed on the depression ' s steep, the common play around the edge of the slope of the depression
發育扇三角洲砂體的東部斷階斜坡帶中下部、發育三角洲砂體的東南凹槽和東北部緩坡帶是最有利的目標區，發育近岸水下扇的西部陡岸帶是較有利區帶，緩坡帶的上部邊緣為一般勘探區。 -
Several normal faults within the hainan fault zone constitute a fault - step zone and form a narrow and steep zone, which controlled the development and distribution of depositional systems in this area
研究認為，海南斷裂帶的幾個北掉斷層構成斷階帶，形成湖盆邊緣陡且窄的地貌特點，控制了該區沉積體系的展布規律。
