摘要
Abstract
As showed by precise isotopic dating results,Yishui group was formed in the 2760~2700Ma,while Yanlingguan formation in Taishan group,Xiayazu formation and Mengjiatun formation in Liuhang group were formed in 2750~2700Ma.They all belong to early period of Neoarchean.Shangya formation and Shancaoyu formation of Liuhang formation in Taishan group were formed in 2600~2540Ma(intruded by quartz diorite rock units in Yishan rock group and monzogranite in Aolaishan rock group),while zircons ages of Jining group was(2561±24)Ma.They all belong to the late Archean.The formation period of Jingshan group and Fenzishan group is late Paleoproterozoic.Detrital zircon U-Pb age of Zhifu group was(1658±32) Ma and(1792±43)Ma.They were formed in the Mesoproterozoic.Detrital zircon U-Pb age of Huaguoshan group is 800~740Ma,and was formed in the Neoproterozoic.关键词
