| 摘 要： | 吉南地区的寒武纪生物化石（以三叶虫为主）极其发育，前人曾对其进行了详尽的研究，先后建立了７个阶１７个化石带。但化石带的含义不甚明确，多以标准分子为代表，即标准化石带（时间带？）。笔者等于１９９１￣１９９３年在白山市幅（１／５万）区调填图时，以区内的青沟子剖面为例，利用前人在该剖面上连续采集的三叶虫生物化石资料，按照多重地层划分的原则，对生物地层单位进行了初步清理，建立了５个正式生物地层单位－延限带

| Abstract: | The Cambrian biogenic fossils(mainly trilobite) are very development in the southern part of Jinn province.The former had studied that in detail and determined 7 stages,17 fossilzones,but the meaning of the fossil zones is not clear,most of them are guide fossils,that are; gtlide fossil zones(Chronostratigraphic zone?).Authors had preliminarily sortted out biostratigraphic units,taking the Qinggouzi section as an example,by using the former's data,according to the principle of the multiple stratigraphic division when we had mapped for the Baishan City sheet(1:50 000) in 1991-1993,and established 5 formal biostratigraphic unitsrangzones,6 non formal biostratigraphic units-bearing biogenic fossil beds. |
