Abstract A comprehensive measurement on Shigouli outcrop section of Devonian Yangmaba Formation in the Longmenshan area of Sichuan Basin,was carried to identify the major characteristics of storm deposition and detail study the tempestite depositional system. The major features of storm deposits in the Yangmaba Formation include storm scouring surface,gutter cast structure,graded bedding,parallel bedding,and hummocky cross-stratification. The Yangmaba Formation developed six different composites of storm sedimentary units. A complete storm sequence pattern in the area is established,including the graded bedding section(Sa),the parallel bedding section(Sb),the hummocky cross-stratification section(Sc),the wave bedding section(Sd)and the mudstone section(Se). The bottom often developed the scour surface and gutter cast structure. Generally,there are two types of tempestites developed in the study area,the near-source storm deposits and far-source storm deposits. According to the profile structure type and sedimentary structure characteristics of storm deposits,the distribution pattern of storm sedimentary sequence in this area is established. The storm deposits developed in the study area have great implications for the reconstruction of palaeogeography,because it indicates that the storm deposits is an important control factor for the development of mixed deposits and the inhibition of the development of reefs in this area.
