摘要: 首次在“阳岭砾岩”的夹层中，获大量微古植物及几丁虫化石，为其时代置于晚寒武世至早奥陶世提供了有力证据。另外，对含义不清的“阳岭砾岩”重新厘定了定义，作为“组”级的正式岩石地层单位。Abstract: Many fossil micropaleophytes and chitinozoans were collected for the first time froni inter-calations of the Yangling psephyte in southwestern Jiangxi, Which furnishes strong evidencefor assigning the age of the Yangling psephyte to Late Cambrian-Early Ordovician. Mean-while, the Yangling psephyte whose connotation was originally ambiguous and vague has beenredefined , and it is regarded as a formal formation-rank lithostratigraphic unit.
