| 摘 要： | 湖北省黄石地区栖霞组出露良好，化石丰富，是化石古生态分析的理想地区。通过化石统计、化石形态功能分析、埋藏学分析和围岩沉积学研究，本区栖霞组中共识别出五个化石群落（从下往上）：①Ｃｒｕｒｉｔｈｙｒｉｓ－Ｏｒｔｈｏｔｅｔｉｎａ（ＣＯ）群落；②Ｓｃｈｕｃｈｅｒｔｅｌｌａ－Ｓｐｏｎｇｅ（ＳＳ）群落；③Ｈａｙａｓａｋａｉａ（Ｈ）群落。④Ｓｐｏｕｓｅ（Ｓ）群落和⑤Ｔｙｌｏｐｌｅｃｔａ－Ｐａｒａｃａｎｉｎｉａ（ＴＰ）群落。化石群落及岩相特点在纵向上和横向上的一致变化，表明本区栖霞组形成于一南高北低的缓坡沉积环境，整个栖霞组为一大的海侵序列构成，各种化石群落和岩相的发展演化均是在这一缓坡沉积背景下形成的。

| Abstract: | Five fossil communities have been recognized in the Qixia Formation,Huangshi,Hubeibased on componental functional morphologic analysis and taphonomic analysis.In ascending order they are:1) Crurityris-Orthotetina (CO) Community; 2) Sclluchertella-Sponge(SS)Commullity; 3)Hayasakaia (H) Community; 4 )Sponge (S) Community,and 5 )TylDeplecta-Paracaninia(TP)Community.They belong to Boucot's Benthic Assemblages 2, 3and 4 respectively.The lateral variations in these commullities indicate that the formationwas accumulated on a carbonate ramp gently dipping northwards on which the Qixiantransgressive successions were developed. |
