| 摘 要： | Ｓｍ－Ｎｄ矿物等时线定年结果表明，菁布拉克岩带基性超基性岩形成于３２０Ｍａ，其形成时代晚于早石炭世早期的火山活动，是塔里木板块与巩乃斯微板块碰撞晚期拉张构造环境的产物。

| Abstract: | Basic and ultrabasic rocks were dated by the Sm-Nd mineral isochron technique.The results show that these rocks were formed at 320 Ma B.P.after the Early Carboniferous volcanism,being products in an extonsion tec-tonic setting at the late stage of collision between the Tarim plate and the Gongnaisi microplate. |
