南极利文斯顿岛赫德半岛中的迈尔斯陡崖组主要是浅变质的石英长石杂砂岩、粉砂岩、泥岩和粉砂岩与泥岩互层等组成的复理石，厚度可能超过3 000 m，形成于浊积扇的上扇和下扇部分，时代可能为晚三叠世。在复理石相岩石中发育一套深水的遗迹化石，共有15个遗迹属、16个遗迹种，其中有10个可以鉴定到遗迹种、两个比较种，4个只鉴定到遗迹属，未鉴定到遗迹种；建立1个新遗迹属及新遗迹种，除新遗迹属种外，其余14个遗迹属，15个遗迹种都曾经在深海复理石相浊积岩内发现过，其中 Belorhaphe, Glockerichnus, Lophoctenium, Rhabdo glyphus, Paleodictyon , Sublorenzinia , Spirophycus , Strobilorhaphe, Tuberculichnus , Cochlichnus 等，属于浊流前产生在复理石相泥岩内的高度分异的雕画迹(Graphoglyptida)，它们产于泥岩却保存为上覆砂岩底面的铸型凸起。另外Fucusopsis和Neonereites却产生在砂岩内代表浊流后形成的沉积后遗迹组合。文内还描述3种浊流常见的无机构造，并与上述遗迹化石进行比较。

The Miers Bluff Formation on Hurd Peninsula, Liv ingston Island, West Antarctica, contains low-grade metamorphic grey-wacke, arkose sandstone, shales, con glomerate, pebbly mudstone and breccias and has been in terpreted to be a sequence of turbidites. It may represent sedimentation of upper and lower mid-fan settings. Its thick is more than 3 000 meters (base unknown). Its de positional age has been palynologically dated as Late Trias sic (Ouyang et al., 2000). Many trace fossils of the whole succession were found in the turbidites of the Miers Bluff Formation. All these are deep sea ichnofossils. Fif teen ichnogenus and sixteen ichnospecies are recongnized. They are Belorhaphe ichnosp., Cochlichnus ichonosp. , Fucusopsis annulata Palibin, Glockerichnus ichnosp., Halyminidium sublumbricoides ( Azpeitia ), Lophocteni um comosum Richter, Neonereites uniserialis Seilacher, Paleodictyon ichnosp. , Paleaichnus antarctics ichnogen. et ichnosp. nov., Planolites montanus Richter, Rhabdo glyphus grossheimi Vassoevich, Spirophycus bicornis Heer, Strobilorhaphe ichnosp. , Sublorenzinia cf. plana Ksiazkiewicz, Tuberculichnus meandrinus Ksiazkiewicz and Tuberculichnus bulbosus Ksiazkiewicz. We found a new trace fossil and propose a new ichnogenus and new ichnospecies－Paleaichnus antarcticus ichnogen. et ich nosp. nov. Except the new ichnogenus and ichnospecies, others had been found in deep-sea flysch turbidites. Some are in mudstone and preserved in the cast convex of over lying sandstone sole. They formed before turbidity flows and belong to the high-different Graphoglyptidas of flysch mudstone, for example Belorhaphe, Glockerichnus, Lophoctenium , Rhabdoglyphus , Paleodictyon , Sublorenzinia , Spirophycus , Strobilorhaphe , Tuber culichnus and Cochlichnus et al. Others as Fucusopsis and Neonereites are preserved in sandstones and stand for trace assemblages after turbidity sedimentation. In addition, the paper also discussed three common inorganic structures in turbidity flow and compared with the above-mentioned trace fossils.
