摘要：

生物造礁造岩作用的关键是阐明生物的古生态和造礁功能。块状、层纹状或板状、分枝状、结壳状和游移或漂浮的不定形状等,不同外形的造礁生物,以不同方式造成五种不同的原地石灰岩:骨架岩、盖覆岩、障积岩、缠结岩和生物粘结岩。同种外形的造礁生物,在各地质时代中的造礁造岩功能和机理是相似的。骨架岩、障积岩和部分盖覆岩可造成原生礁骨架;缠结岩、生物粘结岩和部分盖覆岩一般造成次生礁骨架。

Abstract:

The key of reef-and rock-building role of organisms is to explain their paleoecologic characters and reef-building functions.Different reef-building organ-isms in shapes,such as massive,lamellar or tubular,branching,encrusting and indefinite shapes of vagrant or floating organisms,can construct five kinds of autochonous limestones in distinct ways:framestone,coverstone,bafflestone,bindstone and biocement stone.The same shape of reef-building organisms may have similar reef-building functions and forming mechanisms even in various geo-logical times.That is,framestones,bafflestones and some coverstones may form primary framework of reef;bindstones,biocementstones and some coverstone sgenerally construct the secondary framework of reef.
