摘要: 在野外地质勘查的基础上,运用层序地层学的理论和研究方法,对苏皖下扬子地区石炭系露头进行了精细的层序地层研究和层序划分、对比,详细阐述了层序建立和层序特征。研究结果表明,苏皖下扬子地区石炭系可以分为6个三级层序,其中层序SQ1、SQ5、SQ6属于Ⅰ型层序,层序SQ2、SQ3、SQ4属于Ⅱ型层序。在苏皖下扬子的东北部地区SQ1—SQ6六个层序发育完整,而在西南部地区SQ1—SQ4四个层序存在不同程度的缺失;SQ5、SQ6层序则全区广布。

Abstract: This paper presents a detailed study of outcrop sequence stratigraphy of Carboniferous in Lower Y angtse area of Jiangsu and Anhui Provinces in China, on the basis of field geologic examination, making use of theory and method of sequence statigraphy, and with aid of the detailed stratigraphic classification and correlation in this area, hence the characteristics of the sequence and its establishment are suggested. And the sequence classification and regional correlation of Carboniferous in Lower Yangtse area are discussed. Results show that this area can be divided into 6 third-grade sequences (SQ1-SQ6), among which SQ1, SQ5, SQ6 belong to Type I sequence; SQ2 SQ3, SQ4 to Type II sequence. In northeastern part of Lower Yangtse area, SQ1-SQ6 are completely developed; in southwesterm part of it, SQ1-SQ4 are absent in different degrees; SQ5, SQ6 are distributed in the whole area.

Key words: Jiangsu province, Anhui province, Lower Yangtse area, Carboniferous, sequence stratigraphy, stratigraphic correlation
