| 摘 要： | 综合运用露头、岩心、地震等资料,应用层序地层学和沉积学的理论方法,研究了桂中坳陷中泥盆统罗富组的层序地层特征及沉积演化规律,识别出2个三级层序,分别为SQ1和SQ2。区内的层序界面,在地震剖面上主要表现为上超和削蚀,在垂向上主要出现在地层叠加方式的转换带。通过对基干剖面、辅助剖面和主要钻井资料的分析,绘制了桂中坳陷中泥盆纪东岗岭期（SQ1,SQ2）的沉积体系图。

| Abstract: | In order to study the sequence features and depositional evolution of Luofu middle Devonion Formation in Guizhong depression by the theories of outcrops,drill core,sequence stratigraphy and sedimentology,midlle Devonian outcrops and well drilling data are analyzed carefully.Two third-order sequences are identified and named as SQ1 and SQ2.The methods of identificating sequence boundary are analyzed.Sequence boundary in seismic profile is found to be onlap and truncation in the transiton zone of stacking pat... |
