    Ocean Island Rock Assembly and Its Tectonic Significance in Tangga⁃Sumdo Area, Tibet

    • 摘要: 西藏松多(超)高压变质带对认识古特提斯洋的演化具有十分重要的作用,然而目前关于该带代表的洋盆早期演化记录发现较少,制约了对松多古特提斯洋盆演化的理解. 对唐加地区的洋岛型岩石组合进行了野外地质特征、岩浆岩全岩地球化学和锆石U⁃Pb定年研究.唐加地区洋岛型岩石组合的野外地质特征具有典型的“二元结构”,下层为玄武岩基底,上层为灰岩(大理岩)盖层和塌积砾岩,在上部盖层中还可见变质玄武岩夹层和大理岩与绿片岩互层的现象,与“佛得角型”洋岛类似. 两件玄武岩和一件辉绿玢岩脉的锆石U⁃P定年结果分别为330 Ma、310 Ma和307 Ma,为早石炭世晚期-晚石炭世. 玄武岩和辉绿玢岩均具有较高的TiO2、P2O5和(Na2O+K2O)含量,稀土元素和微量元素组成与OIB类似,显示明显的Nb、Ta富集,在判别图解中落在OIB和板内玄武岩区域,其岩浆源区可能为尖晶石-石榴子石二辉橄榄岩地幔,熔融深度较小.结合前人研究,初步认为松多古特提斯洋早石炭世晚期可能已经发育了初始洋盆,在早石炭世晚期到晚石炭世为慢/超慢速扩张,形成了具有“佛得角型”洋岛特征的唐加地区洋岛型岩石组合.
