南澳大利亚晚元古代沉积剖面是世界晚前寒武纪较好的标准剖面之一。该剖面岩性较为多样,厚度巨大,出露良好,研究程度高,有同位索年龄资料并含有各种各样的生物化石:藻类、迭层石、藻灰结核、大量无骨骼动物印痕及活动遗迹。自从1960年A.和提出把南澳大利亚晚前寒武纪沉积上部划分为国际地层表中一个独立地层单位—埃迪卡拉系后,对其研究的兴趣与日俱增。本文是根据对剖面及其中所含藻类化石和结构的研究而提出的,其目的在于简要地论述这些剖面的地层研究现状并着重讨论
The Late Paleoproterozoic sedimentary section of South Australia is one of the better standard sections of the Precambrian in the world. This section is quite diverse in lithology, with a large thickness, well-exposed, highly studied, isotopic age data and contains a wide range of biological fossils: algae, laminated rock, algal ash tuberculosis, a large number of non-skeletal animal prints and activities remains. Since 1960 A., and his proposal to classify the upper part of the Precambrian sediments of South Australia as an independent strata unit in the international stratigraphic table, Edicika, there has been growing interest in the study. This article is based on the study of the profile and the algae fossils and structures contained therein. The purpose of this paper is to briefly discuss the status of stratigraphic studies of these profiles and to focus on
