| 摘 要： | 独山地区的革老河组和汤粑沟组中含有丰富的遗迹化石，可分为：Ｓｋｏｌｉｔｈｏｓ－Ｄｉｐｌｏｃｒａｔｅｒｉｏｎ，Ｒｈｉｚｏｃｏｒａｌｌｉｕｍ－Ｔｈａｌａｓｓｉｎｏｉｄｅｓ，Ｃｈｏｎｄｒｉｔｅｓ－Ｐａｌａｅｏｐｈｙｃｕｓ，Ｔｅｉｃｈｉｃｈｎｕｓ－Ｐｌａｎｏｌｉｔｅｓ，Ｐｌａｎｏｌｉｔｅｓ－Ｃｏｃｈｌｉｃｈｎｕｓ等５个反映不同沉积环境的遗迹组合，并在剖面上展现出较好的海平面变化。通过对遗迹组合所反映环境的研究，独山地区泥盆系－石炭系界线附近的沉积环境受脉动式海平面升降的影响和控制，界线可能在汤粑沟组底部钙泥质条带灰岩明显海退事件之上的第一次海进层附近。

| Abstract: | There are abundant trace fossils in the Gelaohe and Tangbagou Formations in Dushan,Guizhou, which can be divided into five trace fossil assemblages: (1) Skolithos-Diplocraterion Assemblage, including Skolithos, Diplocraterion and Thalassinoides and belonging to Skolithos ichnofacies of Seilacher. (2) Rhizocorallium-Thalassinoides Assemblage, including Rhizocorallium, Thalassinoides,Ophiomorpha, Palaeophycus and belonging to Glossifungites ichnofacies. (3) Chondrites-Palaeophycus Assemblage, only including Chondrites and Palaeophycus. (4) Teichichnus-Planolites Assemblage, including Teichichnus, Planolites, Phycodes, Chondrites, Palaeophycus and trilobita and belonging to Seilacher's Cruziana ichnofacies. (5) Planolites-Cochlichnus Assemblage, including Planolites, Cochlichnus, Chondrites. These assemblages well display the sea level changes and the Devonian-Carboniferous Boundary may be drawn near the first transgression. |
