| 摘 要： | 浙江省老虎洞组、黄龙组生物地层的研究较薄弱，尤其是笾化石带的建立不够系统，使地层的正确划分和对比存在一些问题。笔者通过精测浙江省桐庐县杨家老虎洞组、黄龙组地层剖面，系统采集了筵化石样品，经筵薄片研究。自下而上新建2个筵化石带：Profusulinella simplex带和FusulineUa bocki—Fusulina mayiensis带(二带化石归属达拉阶)。并与浙江长兴、杭州、常山地区的老虎洞组、黄龙组剖面进行了生物地层和岩石地层的划分对比。对比结果表明：Profusulinella simplex带上延至黄龙组中一下部， |

| Abstract: | The biostratigraphy of the Huanglong and Laohudong formations in Zhejiang is less studied, and especially the fusulinid zone is not systematic. So there are some problems about the correct stratigraphic division and correlation. The authors intensively measured the stratigraphic section of the Laohudong Formation and Huanglong Formation in Tonglu, Zhejiang Province, and gathered samples of fusulinids from the section, and by thin section study the authors established two fusulinid zones; they are in ascending order: the Profusulinella simplex zone and Fusulinella bocki-Fusulina mayiensis zone (both belong to the Dalaan Stage). Moreover, the biostratigraphic and lithostratigraphic correlation has been made between this section and the section of the two formations in Changxing, Hangzhou and Changshan in Zhejiang. The correlation results indicate that the Profusulinella simplex zone may extend upward to the middle and lower parts of the Huanglong Formation. |
