广西隆林地区二叠纪生物礁微体化石与沉积环境研究

ON THE MICROFSSILS OF THE PEKMIAN BIOHERM AND THE SEDIMENTARY ENVIRONMENT IN THE LONGLIN AREA, KUANGXI PROVINCE

作者以广西隆林二叠系生物礁剖面为代表，系统采集和研究了各门类生物化石，以有孔虫、钙藻的生态为特征，自下而上，划分了１２个有孔虫－钙藻组合。从定性及定量分析入手，浅析了生物群落与沉积环境的关系，再造了海域微地貌景观。

Taking the Permian bioherm section of the Longlin area, Kuangxi Province as anexample,the authors systematically sampled and analysed the different phyla of fossils. From lower to upper of the sectionm, 12 assemb ages were clarified for Foraminifera andcalcareous algae by the characterization of their ecology. Consequently, a relationshipbetween the biOcoenose and its sedimentary environments were preliminarily approached, with a view to qualitative and quantitative analyses, the microgeomorphic features for amarine facies were reconstructed.
