| 摘 要： | 精确同位素地质测年结果表明,沂水岩群形成时代为2 760～2 700Ma,泰山岩群雁翎关岩组、柳杭岩组下亚组和孟家屯岩组形成时代为2 750～2 700Ma,均属新太古代早期;泰山岩群柳杭岩组上亚组、山草峪岩组形成时代为2 600～2 540Ma(被峄山岩套石英闪长岩和傲徕山岩套二长花岗岩侵入),济宁岩群岩浆锆石年龄(2 561±24)Ma,均属新太古代晚期。荆山群和粉子山群的形成时代为古元古代晚期。芝罘群碎屑锆石U-Pb年龄(1 658±32)Ma、(1 792±43)Ma,形成时代为中元古代。云台岩群花果山组碎屑锆石U-Pb年龄800～740Ma,形成时代为新元古代。 |

| 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... |
