浙赣交界地区上奥陶统三衢山组礁灰岩的分类

本文讨论了礁灰岩的分类历史，特别对Ｔｓｉｅｎ，Ｈ．Ｈ．的礁灰岩分类系统进行了介绍．浙赣交界地区上奥陶统三衢山组生物礁发育良好，通过对其所含造礁生物的形态及功能分析，区分出五大类礁灰岩，即格架岩、障积岩、盖复岩、绑结岩和生物粘结岩，并指出生物礁礁核相主要由以上各种礁灰岩的复合类型所组成．

CLASSIFICATION OF REEF LIMESTONE IN THE UPPER ORDOVICIAN SANQUSHAN FORMATION IN THE BORDER AREA BETWEEN ZBEJIANG AND JIANGXI PROVINCES

Reefs in the Sanqushan Formation in the border area between Zhejiang Province and Jiangxi Province are very well-developed. Based on the functional morphologic analyses of various reef-building organisms,the reef limestone is divided into five different types,namely, framestone, coverstone, bindstone, baffiestone and biocementstone. This paper proposes that the reef core facies mainly consists of complex reef limestone.
