摘要
Tubiphytes广泛分布在黔南晚石炭世礁相地层中,具有多样的生物形态。其造礁作用以粘结方式为主,可以集中密集形成粘结岩礁块,也可以与其它造礁生物共同建造礁体。其建造的礁体分布局限,礁体一般规模不大。Tub-iphytes在工作区除形成礁体外,还通过包覆其它生物碎屑和粘连灰泥和碎屑颗粒形成粘结岩,构成珊瑚礁体的基底,起到固结基底的作用;也可以在其它礁体内部粘结充填在礁骨架中的灰泥和碎屑颗粒形成块状粘结岩,起到加固礁体的作用。Tubiphytes与其它生物碎屑一起作为碳酸盐岩造岩的重要组成部分,在礁相地层中也广泛存在。Tubiphytes在黔南晚石炭世礁相地层中是一类具有特色的生物。
Tubiphytes are widespread in reef strata of the Late Carboniferous in South Guizhou.They have a variety of morphological forms.The dense Tubiphytes construct the reef rock mainly by binding.They also form the reef with other reef-building organisms in the study area.The Tubiphytes reefs are relative small-size and localized.In the study area,most of Tubiphytes form boundstone by encrusting the bioclasts and binding bioclastic grains and mud,except for forming reef.Tubiphytes boundstone can offer a stable substrate of coral reef by binding sediments.They can also bind the bioclastic grains that filled in the space of coral reefs framework to form a massive boundstone and enhance the stability of coral reefs.As the important component of the carbonate rocks,Tubiphytes also extensively occur in the strata with other bioclasts.Tubiphytes are the characteristic organism in reef strata of the Late Carboniferous in South Guizhou.
