    U-Pb Ages and Hf Isotopes of Detrital Zircons of Nanhua Sedimentary Rocks from the Yangtze Gorges: Implications for Genesis of Neoproterozoic Magmatism in South China

    • 摘要: 对采自宜昌三峡地区南华纪沉积岩中碎屑锆石进行了U-Pb定年,新元古代锆石U-Pb年龄在833Ma、785Ma出现高峰,说明此时期有两期大规模岩浆活动.结合前人的Hf同位素结果,新元古代锆石U-Pb年龄与εHf(t)值关系图表明: 910~890Ma之间锆石εHf(t)值表现为高正值(≈10,接近亏损地幔演化值),890~840Ma锆石εHf(t)值明显降低,并有负值出现,另外在890Ma处有年龄峰出现.笔者认为扬子和华夏板块的拼合可能在890Ma发生了由俯冲到陆-陆或陆-弧的碰撞,之前的高εHf(t)值由洋壳俯冲造成,之后碰撞作用陆壳物质熔融造成了εHf(t)值的降低; 840~800Ma的锆石εHf(t)值有正也有负,800~780Ma的锆石εHf(t)值小于0,780~750Ma的锆石εHf(t)值大于0.这些数据与830~795Ma、780~745Ma两期地幔柱事件吻合.
