中扬子区海相沉积盆地性质研究

STUDY ON THE CHARACTER OF MARINE SEDIMENT BASIN IN THE MID-YANGTZE AREA

分析了中扬子区海相沉积盆地基底和层序充填特征 ;研制了 M判别图解 ;研究了沉积盆地的性质 ,认为盆地基底具有三分性 ,盆地层序充填具有阶段性和分区性 。

The character of sequence fills and the basement of the marine sediment basin in mid Yangtze area were analyzed, and a map called 'M' was developed while the character of marine sediment basin was studied. As a result, the basement could be divided into three parts, the sequence fills could be identified as several stages and varied distribution, and the body character of the basin showed as a craton one.
