对首次在吐哈盆地台北凹陷侏罗系发现的分布于不同剖面、不同层位中的动物遗迹化石进行了系统研究。主要分析了研究区内动物遗迹化石的特征 ,将之划分为六大类型 :( 1 )垂直居住迹 ;( 2 )垂直觅食迹 ;( 3 )“U”形管 ;( 4)潜穴系统 ;( 5)逃逸迹 ;( 6)停息迹。较详细地分析了各类型的形态特征和保存特点 ,简要分析了造迹生物的行为习性及环境意义。在此基础上 ,建立了本区动物遗迹化石的环境模式。同时指出 ,遗迹化石在陆相含油气盆地确实大量存在 ,并在储层研究中具广泛的实践意义。
Animal trace fossils, which were found in the Jurassic in Taipei depression of the Turpan-Hami basin in different sections and in different layers, were systematically studied. This paper mainly analyzes the characteristics of animal trace fossils in the study area and divides them into six major types: (1) vertical living trace; (2) vertical feeding trace; (3) “U” shaped tube; ; (5) Escape track; (6) Stop track. Analyzed the morphological characteristics and preservation characteristics of each type in more detail, and briefly analyzed the behavioral habit and environmental significance of pathogenic organisms. On this basis, we established the environmental model of animal trace fossils in this area. At the same time, it is pointed out that trace fossils do exist in a large number in continental oil-gas basins and have extensive practical significance in reservoir research.
