吉林辽源西保安群花岗质糜棱岩SHRIMP U-Pb定年
锆石U-Pb年龄 西保安群 吉林辽源
2014/7/7
吉林辽源西保安群是大面积花岗岩侵入体中的残留的构造岩片,传统认为属于华力西晚期或中侏罗世花岗闪长岩-二长花岗岩系。本文通过对接触界线附近花岗质糜棱岩样品采集和锆石SHRIMP U-Pb定年,获得多组锆石年龄值为236~231Ma、267.6~358.6Ma、416.3±6.8Ma、956±16Ma。认为该区花岗岩的侵入期次相当复杂,发育有早中三叠世岩体和发生了中、晚华力西期岩浆活动,西拉木伦河碰撞...
青海岗察岩体SHRIMP锆石U-Pb年龄及其地质意义
SHRIMP锆石U-Pb测年 岗察岩体 侵入期次 西秦岭 青海
2014/10/14
青海岗察岩体位于西秦岭造山带的西段,由闪长岩、花岗闪长岩、斑状花岗闪长岩体组成,各岩体虽然地质特征和岩性有所差异,但成因和形成的时间基本一致,是不同时期同一成因的产物,由早向晚由中性向酸性演化,属“I”型花岗岩系列。尽管前人对其中个别阶段岩体进行过年龄测定,但没有对多期岩体进行过系统的年代学精测。本文在运用阴极发光技术对岩体中锆石进行细致的内部结构分析的基础上,利用SHRIMP锆石U-Pb原位定年...
