1.In addition to ultrahigh pressure(UHP) metamorphic complex, the granitic gneiss is another important rock type in southeastern Dabie Mountains. The granitic gneiss yields 789±43 Ma based on the U Pb zircon concordia upper intercept.
花岗片麻岩是大别山区除超高压变质杂岩外的另一种重要岩石类型 ,本文测得南大别二长花岗片麻岩中单颗粒锆石U Pb不一致线的上交点年龄为 789± 43Ma。收藏指正
2.A Study of Zircon U-Pb Dating and Oxygen Isotopes in UHP Granitic Gneiss from the Weihai Region in Northeast Sulu
威海地区超高压变质花岗片麻岩锆石U-Pb定年和氧同位素研究收藏指正
3.Precise Restriction of Non-UHP Granitic Gneiss from the UHP Metamorphic Belt in the Sulu Terrane, Eastern China: Evidence from Mineral Inclusions,Cathodoluminescence Images and SHRIMP U-Pb Dating in Zircon Domains
苏鲁超高压变质带中非超高压花岗质片麻岩的准确识别:来自锆石微区矿物包体及SHRIMP U-Pb定年的证据收藏指正
4.SHRIMP U-Pb dating of zircons from Lgn gneiss enclave and NG granite yielded ages of 65.0～55.0 Ma and 18.3～11.1 Ma, representing periods of granitic magma crystallization in Palaeocene and Miocene respectively.
在18.3～11.1Ma期间,在约11km深度的Lgn、Ygn下方发生大规模岩浆侵位和结晶成岩事件,形成念青唐古拉黑云母二长花岗岩(NG)。收藏指正
5.The early Archaeozoic metamorphic complex in the west of Liaoning consists of 85%-90% of felsic gneiss including mainly pluntonic granitic complex with quartz diorite-granodiorite-granite (TTG) assemblage,and 10%~15% of upper crust rock including layered volcanic-sedimentary rock,dike rock and basic-uitrabasic instrusives.
辽西早太古宙变质杂岩是由85%～90%长英质片麻岩(主要是英云闪长岩—花岗间长岩—花岗岩组合(简称TTG)的深成花岗杂岩)和10%～15%上壳岩(包括层状火山—沉积岩、脉岩及基性超基性侵入岩等)组成.收藏指正
6.The tectonites in this zone include tectonic gneiss and mylonite. The biotite from the granitic mylonite gives a 40Ar/39Ar age of 105.2±1.7 Ma,implying that the ductile shear zone may be traced back to the Early Cretaceous.
带内所形成的构造岩主要为构造片麻岩和糜棱岩类,对花岗质糜棱岩中的黑云母进行40Ar/39Ar年龄测试,获得105.2±1.7Ma,认为该韧性剪切带形成于早白垩世。收藏指正
