甘肃北山大山头南花岗闪长岩SHRIMP锆石U-Pb定年及其地质意义
|
摘要
采用SHRIMP锆石U-Pb定年方法,首次获得大山头南出露的片麻状花岗闪长岩的~(206)Pb/~(208)Pb加权平均年龄为(386±6)Ma(MSWD=1.06),代表该岩体的成岩年龄,即大山头南花岗闪长岩岩体形成于中泥盆世。于此同时,首次获得了花岗闪长岩中部分继承锆石的年龄为(885±20)Ma(MSWD=1.18),该年龄是新元古代构造热事件的反映。该岩体成岩年龄介于其北侧的大山头超镁铁岩体(397±4)Ma和大山头南超镁铁岩体(374±3)Ma之间,结合研究区地质构造背景及前人研究成果,认为中晚泥盆世期间不仅有中酸性岩浆侵位,同时沿大断裂带也有部分镁铁-超镁铁岩侵位,中酸性岩体与镁铁-超镁铁岩体可能具有类似的地质背景,即它们均形成于后造山或同造山晚期阶段。
Using the SHRIMP zircon U-Pb dating methods,the diagenesisage of the Dashantounangranodiorite has been obtained for the first time.The obtained ~(206)Pb/~(208 )Pb weighted average age is(386±6)Ma(MSWD=1.06),standing for the Dashantounan granodiorite was formed in middle Devonian.At the same time,the inherited zircon age has been obtained for the first time,and the yielded age is(885±20)Ma(MSWD=1.18),whichserves as a reflection of the Neoproterozoic tectonic-thermal event.The diagenetic age between the age of Dashantourock mass(397±4)Ma and the ones of Dashantounan rock mass(374±3)Ma.After analyzing the previous research achievements,it’s believed that themagmatic intrusionin the Middle-lateDevoniannot only includeintermediate-acidic magmas,but also include basic-ultrabasicmagma in the studying area.Theintermediate-acidic and basic-ultrabasicmagma might be formed in the same geological background,that is,theymight beformed in a post-orogenic extensional setting or a late-stage of syn-orogenic setting.
