通过对安徽东至建新剖面红花园组的生物礁、微生物岩进行研究,发现蓝绿菌类Girvanella在生物礁中大量分布,是生物礁的主要造礁成分。其他造礁生物包括瓶筐虫、石海绵、腹足类、腕足类、棘皮类等。Girvanella以散乱分布、包壳、组成内碎屑以及与海绵伴生等4种方式在本区生物礁中存在,并且在生物礁成礁过程中以生物本体矿化作用及粘结、捕获颗粒的作用形成生物礁格架;瓶筐虫及石海绵为生物礁中的居住者,因此,生物礁性质为瓶筐虫/石海绵-微生物礁,微生物起到了主要的造礁作用。此外红花园组典型含生物礁沉积序列是由底部的生屑灰岩基底、中部的海绵层(少量微生物岩)及顶部的微生物岩组成的。通过与其他地区同时代生物礁的对比发现,东至建新剖面红花园组中瓶筐虫/石海绵-微生物礁的发育及微生物的繁盛是全球性的,是由于底栖生物扰动对潮下带微生物发育影响尚未彰显造成的。
Based on the reefs and microbial rocks in the Honghuayuan Formation in East Zhijian, Anhui Province, the blue-green fungus Girvanella is found in a large number of reefs and is the major reef component of reefs. Other reef creatures, including bottle basket insect, stone sponge, gastropods, brachiopods, echinoderms and so on. Girvanella exists in reefs in this area in 4 ways including scattered distribution, crusting, internal fragmentation and sponge associated with sponge. In addition, Girvanella catches the role of particles by bio-mineralization and bonding during reef reef formation Forming reef shelves; bottleworm and stone sponge reef living in reefs, therefore, the nature of the reef aquarium bottleworm / stone sponge - microbial reef, microbes play a major reefing role. In addition, the typical sequence of reef-containing deposits in the Honghuayuan Formation is composed of a base of bioclastic limestone, a sponge layer in the middle (small amount of microbial rock), and a top microbial rock. By comparing with the contemporary reefs in other areas, it is found that the development of the bottleworm / stone sponge-reefs and the flourishing of microorganisms in the Honghuayuan Formation in the Dongzhijian section are global due to the disturbance of benthic organisms to the subtidal zone Microbial development has not yet caused the obvious.
