【摘要】 运用地震地层学方法 ,在笔架南盆地识别出 5个特征明显的反射界面 ,划分了 3个超层序、5个地震层序 ,并探讨各地震层序的地质时代。通过地震相沉积相推测分析 ,认为地震层序E主要发育火山碎屑岩相 ;地震层序D主要发育半深海偏泥相 ;地震层序C主要发育半深海泥岩相 ;地震层序B主要发育半深海—深海泥岩相和浊积偏砂相 ;地震层序A主要发育深海泥岩相、深海三角洲泥岩相和浊积偏砂相更多还原

【Abstract】 From seismic stratigraphy, the authors identify five seismic reflection interfaces and differentiate five seismic sequences and three supersequences. Geologic age of seismic sequences is confined to a certain degree. Seismic facies and sedimentary facies are analyzed. There developed pyroclastic rock in the Late Oligocene in the basin, bathyal mudstone and a little sandstone in the Early Miocene, bathyal mudstone in the Middle Micocene and the Late Miocene, bathyal\|deep sea mudstone and turbidite in the Pliocene, and deep sea mudstone, deltaic mudstone and turbidite in the Quaternary.更多还原
