Abstract:

?南阿尔金俯冲碰撞杂岩带早古生代存在517,501~496,462~451和426~385Ma四个期次的花岗质岩浆岩.第一期岩浆岩侵位于区内蛇绿岩型镁铁质岩石之中,后三期分别对应于该构造带高压-超高压岩石~500Ma的峰期变质及其~450和~420Ma的两期退变质时间.结合区域地质背景、镁铁-超镁铁质岩和高压-超高压变质作用研究成果综合分析,这四期岩浆岩分别是南阿尔金早古生代板块俯冲碰撞过程中,先期俯冲洋壳,之后陆壳深俯冲导致地壳加厚引发下地壳以及深俯冲板片断离导致中上地壳和造山后伸展减薄阶段部分熔融作用的产物.其中,洋壳型埃达克岩的形成时代(517Ma)为南阿尔金洋壳俯冲作用时限提供了直接约束,陆壳深俯冲引发的高压-超高压峰期变质时代(~500Ma)作用滞后这一事件约10Myr,表明南阿尔金早古生代时期由洋壳俯冲转换为陆壳俯冲可能是一个连续的构造演化过程.这四期花岗质岩石与区内蛇绿岩型镁铁-超镁铁质岩石以及高压-超高压变质岩石的形成,共同记录了南阿尔金早古生代时期从大洋俯冲、之后的大陆深俯冲碰撞再到后来深俯冲陆壳折返抬升的完整构造演化过程.
