  • Based on the outcrop measurement and indoor identification to the Luoreping Formation in southern Micangshan,it has been found that there are many tempestites in the Luoreping Formation of Middle Silurian in southern Micangshan, developing ditch structures, gravel-sized grain structures and graded bedding. The main lithology are mud shale, micrite and bioclastic limestone. There are three kinds of sedimentary sequences in the tempestites which show a certain inheritance. This is distal storm deposit and shallow shelf sedimentary environment. The discovery of storm-induced rocks in the area has explained the causes of the biological limestone lenticle, providing new standard for regional stratigraphic isochronous correlation and basis for the evolution of ancient geography, climate and Yangtze basin development. This study indicates that the later Luoreping Group sedimentation period in Nanjiang area has been in low latitude areas where storms frequently take place.

Abstract: Based on the outcrop measurement and indoor identification to the Luoreping Formation in southern Micangshan,it has been found that there are many tempestites in the Luoreping Formation of Middle Silurian in southern Micangshan, developing ditch structures, gravel-sized grain structures and graded bedding. The main lithology are mud shale, micrite and bioclastic limestone. There are three kinds of sedimentary sequences in the tempestites which show a certain inheritance. This is distal storm deposit and shallow shelf sedimentary environment. The discovery of storm-induced rocks in the area has explained the causes of the biological limestone lenticle, providing new standard for regional stratigraphic isochronous correlation and basis for the evolution of ancient geography, climate and Yangtze basin development. This study indicates that the later Luoreping Group sedimentation period in Nanjiang area has been in low latitude areas where storms frequently take place.
