四川盆地西南部茅口期岩相古地理
Lithofacies Palaeogeography of Maokou Period in Southwestern Sichuan Basin
摘要
Abstract
According to the data from field outcrops, drilling section and well logging, the Hthologic characteristics and litho-facies palaeogeography of Maokou Formation in southwest Sichuan Basin are analyzed- The results indicated that Maokou Formation developed beach and open sea microfacies in southwest Sichuan basin and can be divided into three sedimentary cycles, which represent the three sea-level fluctuations in Maokou period. The second sedimentary cycle, the phase that sea level decline, becomes the most important period when shallow beach developed widely with the litholgy of sparite bioclastic limestone and partial dolomite. Transformed by the later Dongwu movement, shallow beach can be favorable reservoir.关键词
