By the single zircon U Pb dating method, the quartz syenite porphyny yielded an age of concordance (1 731±29)Ma, and the aegirine augite syenite and syenogebbro are dated upper cocordi...
应用单锆石U Pb法测定年龄,石英正长斑岩谐和年龄为( 1731± 2 9)Ma ,霓辉正长岩、正长辉长岩上交点年龄分别为( 1644± 14)Ma、( 1750± 65)Ma.1650~ 170 0Ma是碱性岩浆活动热构造事件的标志,石英正长斑岩被中元古代晚期的高山河组不整合覆盖,故以 1650~ 170 0Ma作为熊耳群的上限。1650~ 170 0Ma热构造事件是华北地块重大地质事件,有可能是进一步划分中元古代重要的年龄界限。
