摘要: 为了探索层序地层岩相古地理编图方法,对四川盆地晚二叠世生物礁层序地层岩相古地理进行了编图试验,以四川盆地晚二叠世生物礁各层序地层的海退低点及海侵高点作为相对等时面编制了8幅层序地层岩相古地理图.层序地层岩相古地理图不仅能极大地减少由传统的压缩法和优势相编图法所造成的模糊失真现象,而且提高了对沉积和构造演化规律的预测水平.

Abstract: In order to determine a mapping method for sequence stratigraphy lithofacies and paleogeography,the mapping test for sequence stratigraphy lithofacies and paleogeography of the Late Permian reef in Sichuan Basin was carried out.Eight maps of sequence stratigraphy lithofacies-paleogeography were given,on the basis of the isotime surface of each sequence at lower point of marine regression and high point of marine transgression in the Late Permian reef in Sichuan Basin.The sequence stratigraphy lithofacies_paleogeographic map not only reduced the distortion derived from the traditional predominance or compress mapping methods but also promote the prediction of sedimentary and basin evolution laws.

Key words: Sichuan Basin, Late Permian, reef, mapping, sequence stratigraphy, lithofacies-paleogeographic map
