| 摘 要： | 利用高分辨率三维地震资料,在珠江口白云凹陷三维工区中发现形态以及发育特征相似的7个海底峡谷.通过对其现今地貌特征研究,将其分为上、中、下段.综合地震反射振幅、连续性及外部结构形态等信息,识别出了峡谷侵蚀基底、谷底沉积、谷壁滑塌等峡谷地震相单元.结合峡谷不同位置处的各类地震相的发育情况,可知峡谷的这3个地貌单元具有不同的...

| Abstract: | Based on the high resolution 3D seismic data,seven submarine canyons are studied on their morphological and sedimentary characteristics in a block in the Baiyun Sag,northern South China Sea.Upon morphological features,the canyons are divided into three segments,namely upper,middle and lower segments.According to the continuity and amplitude of the reflection,integrated with seismic reflection configuration,the basal erosional discontinuity and two seismic facies,i.e.thalweg facies and slide facies,were reco... |
