摘    要:黔南晚石炭世普遍发育了一套台地相的碳酸盐岩地层,其中多种底栖生物十分繁盛,为深入开展石炭纪生物礁研究提供了有利条件。近几年,随着研究的不断深入,笔者等陆续发现了一些新型的造礁生物,其中一种重要的造礁生物是一种类似藻类的生物。通过大量的野外观察和室内工作,笔者等发现:这种生物是黔南晚石炭世的重要造礁生物类型之一,它在台地边缘生物碎屑滩上以多种生长方式构建礁体。该生物具有两种生长形式:一种是生物体呈波状延续生长,弯曲环绕,层层叠置形成不同类型的纹层或席状;另一种是生物体在纵向和横向上相互交叉,构成规则或不规则的网格状形态。这种礁体的发现,丰富了石炭纪生物礁的类型。

关 键 词:贵州  晚石炭世  造礁生物  古生态  生物礁

Abstract:A series of platform facies carbonate develops widely in the south of Guizhou Province, which contains abundant benthonic organisms, and they provide advantage condition to the study of Carboniferous reef. In recent years, with the development of reef study, some new-style reef-building organisms were found, one of which is an important reef-building organism which is similar to alga. The organism were found to be one of the important reef-building organism of late Carboniferous in Southern Guizhou through much field and office work, and they built framework reefs by different growth forms on the biodebritus banks of the platform margin. The organism have two growth forms: one is continued undulant, curving and rounding, layers superposed laminae or sill-like; the other one is vertical and horizontal crossed, regular or irregular network. The reef enriches the Carboniferous reef types.
Keywords:south Guizhou  Late Carboniferous  reef-building organism  palaeoecology  reef
