    盆地規模的沉積旋迴多是盆地幕式裂陷、多幕擠壓撓曲沉降、多期構造反轉、斷塊差異沉降等構造作用的沉積回應；高頻層序單元的發育則主要與湖平面和沉積物供給量的變化有關。
  4. The depositional character of zhuxiang formation in the basin reads as follows : a series of nne alluvial fan were formed along the fault. the half - deep lake to deep lake faces appeared by west side of the fault, towards the west the saucer lake faces, shore deposit and flood plain face appeared in proper order. the depositional center of lower cretaceous was formed in eastern part of the basin, and the depositional depth was pinch - out and thinning out from the east to the west

    盆地內下白堊統朱巷組沉積特徵表現為：沿郯廬斷裂帶呈北北東向廣泛發育了沖積扇體系，從近斷裂帶西側出現的半深湖-深湖相，向西依次為濱淺湖相到泛濫平原相的規律性分佈，沉積厚度由東向西尖滅、超覆，構成了明顯的東斷西超的盆地構造格局，表明下白堊統的沉積中心依然位於盆地東部。
  5. The lithological traps related to jishan delta ? turbidite fan depositional system inherently developed during the base level falling period of c3 cycle and the base level rising period ; the lithological traps related to the underwater fan depositional system near xiakou fault developed during c2 cycle ; the lithological traps related to qudi fan delta developed during the base level falling period of c2 cycle ; and there are a few lithological traps related to shangfeng delta. these predicted traps are mainly distributed in the deeply low - lying areas

    在沉積體系、沉積相研究的基礎上，對臨南窪陷沙三段巖性圈閉分佈作出了預測，指出了各旋迴基準面下降期是尋找巖性圈閉的有利層序地層位置， （扇）三角洲前緣滑塌作用或快速充填作用形成的濁積扇或滑塌作用形成的濁積巖體是巖性圈閉形成的主要場所。
  6. There are 5 depositional systems in the region. they are : panhe and jishan delta systems coming from chengning heave near the northwest border of the region, shuangfen delta located in southwest part of the region coming from luxi dome, qudi fan - delta located in the southeast of the studying area and the sub - fan near fault or fan - delta of the southern part of the region

    確定了沙三段沉積時期發育的五種沉積體系類型，即來自凹陷西北邊界埕寧凸起的盤河三角洲體系和基山三角洲體系、來自魯西隆起、分佈在凹陷西南部的雙豐三角洲體系、東南部的曲堤（扇）三角洲體系，南部的近岸水下扇/扇三角洲體系。
  7. 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。
  8. Appearance of marginal faces, parallel depositional center near the tan - lu fault zone, the obvious faulted down boundary in the eastern part and the overlapping boundary from east to west inside the basin indicated that the fault zone occurred as the eastern boundary of the basin in jurassic and acted as provenance of the basin in east due to strike - slip uplifting of the zhangbaling belt

    這些逆沖推覆構造在靠近郯廬斷裂帶附近，具有顯著增多的特點；盆地內侏羅系地層在郯廬斷裂帶一側廣泛發育了邊緣相及與斷裂帶平行的沉積中心，沉積厚度東厚西薄，在盆地東部形成了明顯的斷陷邊界，向盆地內部北西方向則顯示了沉積超覆邊界的特徵。
  9. The structural slope - break zones are defined as the depositional slopes abrupt change in geomorphology and developed widely in fault and foreland basins, the recognition of which is significant for predicting the distribution of depositional systems tracts, particularly the lowstand systems tracts which usually comprised economically important reservoirs in these basins

    構造坡折帶是由構造活動所產生的、對沉積作用具有長期控製作用的古沉積斜坡或古地貌突變帶，在斷陷或前陸等盆地中普遍發育，其識別對闡明盆內沉積體系域，特別是構成重要油氣藏的低位域的分佈和預測具有重要意義。
