| 摘 要： | 本区下第三系地层中发育有大量的遗迹化石,类型多,分异度大。按其生态习性分为六大类:居住迹(Domichnia)、觅食迹(Fodichnia)停迹(Cubich-nia)、爬迹(Repichnia)、逃逸迹(Fugichnia)和牧食迹(Pascichnia),共计13个属。文中描述了类属的特征及其成因,并建立了适于本区的遗迹化石相模式,由五个相组成,即石针迹(Skolihtos)相、卷迹(Intortusichnus) 相、伸展迹(Aductusichnus)相、始网迹(Protopaleodictyon)相和古网迹(Paleodictyon)相,分别对应于滨湖、浅湖上部、浅湖下部、半深湖和深湖环境

| Abstract: | Trace fossils or ichuofossils in the said region arc welldeveloped both in quantity and in diversity. According to their ecological behaviors, they are divided into six types, including Domichnia, Fodinichnia, Cubichnia, Repichnia, Fugichnia and Pascichnia, altogether 13 varieties. The features and genesis of the types and the varieties are described. A lacustrine facics model of trace fossils was established with Ichuofacies of Skolithos, intortustchnus,Aductusichnus, Protopaleodictyon, and Paleodictyon, corresponding to ihe shore-lake, I, he upper shallow-lake, the lower-shallow lake, semideep-lake and deep-lake environments. |
