摘要
近十年来,我国东部沿海地区新生界碳酸盐岩,特别是生物灰岩的含矿性,已引起人们广泛的注视。其中海相生物化石的发现,涉及到碳酸盐岩的形成环境和我国东部早第三纪地质发展历史。为此,1976年笔者对㘵心群碳酸盐岩进行了野外调查及室内研究,首次发现了有孔虫、虫管、藻类等化石及藻叠层石。本文将简要地叙述碳酸盐岩的特征,并探讨其形成环境。
The carbonate rocks of the lower Tertiary Buxin group in Sanshui Basin,Guandong province spread along the basin’s margin may be subdivided into seven deposit areas,where for the first time were found foraminifera(Miliolids,Discorbidae,Nonionidae and Spirillinidae),worm tube(Sedentaria),algae and stromatolites.Judging from the data on petrology and paleontology,The area concerned was transgressed by sea waters during the Buxin epoch.
