本文通过对该区地层剖面及古生物的初步研究,发现在震旦系——寒武系边界层位存在有丰富的小壳化石、三叶虫、古介形虫、海绵、遗迹化石及迭层石等。笔者根据国际地科联关于层型剖面的标准,对本区震旦系——寒武系界线的划分进行了论述,提出了新的看法,并与邻区作了对比。 Based on the preliminary study of the stratigraphic and paleontology in this area, we find that there are abundant small shell fossils, trilobites, ancient ostracods, sponges, trace fossils and laminated layers in the Sinian-Cambrian boundary layer Stone and so on. According to the international standards of stratigraphic section of the ISKEL, the author discusses the division of the Sinian-Cambrian boundary in this area, puts forward a new view and makes a comparison with its neighboring areas.
