山东古生代生物地层单位的划分

DIVISION OF PALEOZOIC BIOSTRATIGRAPHIC UNITS IN SHANDONG

摘要:

本文按照不同生物地层单位的含义，对山东古生代生物地层单位进行了厘定，共划出４１个生物带，其中寒武纪有２１个；奥陶纪１０个，包括３个哑层间隔带；石炭纪３个；二叠纪７个。这些生物地层单位的确立，对统一山东古生代生物地层单位的划分和推动今后的区调工作将起到重要的作用。

According to the definition of different biostratigraphic units,the Paleozoic biostratigraphic units in Shandong can be divided into 41 biobelts.Of them,21 belong to Cambrian;10 belong to Ordovician,including 3 barrenbed interval zones;3 belong to Carboniferous;7 belong to Permian.The determination of the units will play an important role in uniting the division of Paleozoic biostratigraphic units in Shandong and in improving geological regional survey in the future.
