Sequence Stratigraphy of Carboniferous in Lower Yangtse Area of Jiangsu and Anhui Provinces

Abstract

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
