摘要
广西早石炭世生物礁研究甚少,仅有方少仙、侯方浩(1986)曾报道过田林浪平珊瑚—苔藓虫礁,而来宾叠层石藻礁的发现为早石炭世生物礁增添了新的内容。本文通过对叠层石的形态、礁岩组合及沉积序列的描述,探讨成礁环境,认为来宾叠层石礁属于发育在台缘缓斜坡上的丘礁群;并说明叠层石仅局限于潮坪和潮下浅水环境。
The Early Carboniferous reefs have been studied very little except Langping bryozoan ?coral reef in Tianlin was reported by Fang Shaoxian and Hou Fanghou in 1986. The discovery of the stromatolitic algal reef in Laibin has added new contents for Early Carboniferous reefs. Based on the form of stromatolite,the association of reef rocks and the sedimentary sequence,this paper has discussed the reef-forming environment, believed that the stromatolitic algal reef in Laibin belongs to the mound-reef community in the gentle slope of margin platform,and the stromatolite is limited to the environment of tidal flat and subtidal shallow water.
