| 摘 要： | 在西澳大利亚坎宁盆地泥盆纪生物礁组合和东澳大利亚昆士兰州密西西比纪生物礁详细调查和研究的基础上, 通过分析晚泥盆世至密西西比纪生物礁组合在古特提斯海4个不同地区的发育形式和演化特征对西澳大利亚坎宁盆地与中国桂林晚泥盆世生物礁组合以及东澳大利亚昆士兰与中国广西和西日本秋吉台密西西比纪的生物礁进行对比.第一次从构造、地层、古纬度和古气候方面来探讨古东特提斯海和北特提斯海晚泥盆世至密西西比纪生物礁的发育异同, 研究成果改进了对西澳大利亚、东澳大利亚、华南和西日本4个地区生物礁发育的认识, 从而可在全球角度上去探讨控制晚古生代生物礁发育的各种因素.研究的地质时段包含重要的生物绝灭事件, 也是温室向冰室的转折时期, 是全球范围造礁生物演替、更新和重新繁盛的阶段.研究成果对认识晚泥盆世至密西西比纪全球范围内造礁生物和生物礁类型与早、中泥盆世的区别, 对研究全球在这一时期古气候和古环境的变化都具有重要的意义.

Effect of Different Tectonic-Stratigraphic Settings on Late Devonian and Mississippian Reefs in Western Australia,Eastern Australia,South China and Japan |

| Abstract: | The Devonian reef complexes in the Canning basin of western Australia and the Mississippian reef in eastern Australia were compared with those coeval reef complexes in Guilin and Mississippian reefs in Guangxi, South China, and in Akiyoshi, Japan based on the detailed studies on the Devonian reef complexes in Canning basin, western Australia and Mississippian reefs in eastern Australia and through analyzing the development pattern and evolution characteristics of Devonian and Mississippian reefs in four different paleotethys areas. The difference in reef development during the Late Devonian to Mississippian between eastern paleotethys and northern paleotethys was discussed with respect to tectonics, stratigraphy, palaeolatitude, and palaeoclimate, which greatly improves our understanding of Late Devonian to Mississippian reef development in western Australia, eastern Australia, South China, and western Japan respectively, so that the different factors that controlled the reef development in Late Paleozoic were discussed in a global perspective. The geologic interval relevant to this study comprises the important biotic extinction events, it is also a transitional period from greenhouse to icehouse and a stage of evolution, regeneration, and resuscitation for reef-building organisms. The research results are significant in understanding the difference between Late Devonian to Mississippian and early to middle Devonian reef-building organisms and reef types globally and in studying the global palaeoclimatic and palaeoenvironmental changes in this time interval. |
