Abstract:

本文报道在庐山筲箕洼组中获得细碧岩SHIRMP锆石U-Pb年龄(840±6)Ma,MSWD=1.3,流纹岩锆石U-Pb年龄(833±4)Ma,MSWD=1.4,和流纹岩锆石U-Pb年龄(831±3)Ma,对应的MSWD=1.47。而在星子群流纹岩中获得206Pb/238U年龄为(825±5)Ma,对应的MSWD=0.46。笔者依据上述精确锆石年龄,首次提出将筲箕洼组明确定位于星子岩群之下。本文结合“江南造山带”锆石U-Pb年龄:东部变质基底的双桥山群,西部变质基底梵净山群和似盖层下江群以及中部变质基底冷家溪群和似盖层板溪群的锆石SHRIMPU-Pb年龄,将筲箕洼组定位于“武陵运动”之下的新元古代地层。依据星子岩群年龄数据,首次将星子岩群明确定位于筲箕洼组之上与双桥山群为同期的深变质岩。该年龄对限定区域地层对比和构造演化都有着重要意义。上述锆石U-Pb年龄标示了赣西北地区同样存在820Ma界面上下的新元古代地层,为江南古陆变质地层的对比提供了新的年代学数据。
