The Precambrian-Cambrian boundary (PCB), the events leading up to it and the subsequent bioradiation(s) continue to be an enigma in Earth History and demonstrate that we are still unable to convincingly explain the mechanisms and large-scale interactions between the bio-, hydro-, atmo- and geosphere on our planet even at a fundamental level. Although considerable advances have been made in documenting changes and hypotheses abound, many studies tend to focus on narrow aspects or apply a limited set of techniques and tools and are therefore vulnerable to alternative explanations. Our studies over the past three years, in contrast, have the ambition and structure to be regionally and disciplinarily firmly integrated. In continuing our Forschergruppe, we suggest to consolidate our knowledge and understanding of Ediacaran and Cambrian processes and environments based on the classical Yangtze Craton sections, to selectively modify research methods and to expand into other regions in order to generalize our knowledge.

前寒武纪-寒武纪边界（PCB）、导致其发生的事件以及随后的生物辐射仍然是地球历史上的一个谜，这表明即使在基本层面上，我们仍然无法令人信服地解释地球上生物、水、大气和地圈之间的机制和大规模相互作用。尽管在记录变化和假设方面已经取得了相当大的进展，但许多研究往往集中在狭窄的方面或应用有限的技术和工具，因此容易受到其他解释的影响。相比之下，我们过去三年的研究具有在区域和学科上牢固整合的雄心和结构。在继续研究组的过程中，我们建议以扬子克拉通经典剖面为基础，巩固对埃迪卡拉纪和寒武纪过程和环境的认识和理解，有选择地修改研究方法，并扩展到其他地区，以推广我们的知识。
