内蒙古苏左旗洪格尔地区新发现晚石炭世碱性花岗岩
|
摘要
兴蒙造山带中段二连-东乌旗地区发育一条晚古生代碱性花岗岩带,代表了碰撞后伸展背景,前人研究多认为其形成于早二叠世中晚期,本次在苏尼特左旗洪格尔地区新识别出晚石炭世(302±1 Ma)碱性花岗岩,与区域上其它晚石炭世碱性花岗岩共同构成了晚石炭世碱性花岗岩带,表明区域上存在晚石炭世(301～303 Ma)和早二叠世(272～290 Ma)两期碱性花岗岩岩浆活动。
Late Paleozoic alkaline granite belt along Erlian-Dongwuqi area indicate post-collisional extension setting. Most researchers suggested that these granites had formed in middle-late stage of early Permian. In this papers, the authors discover late Carboniferous alkaline granite with zircon U-Pb age of 302 ± 1 Ma in Honger,Sunidzuoqi, Inner Mongolia. The study hint that there were two episodes of alkaline granites along Erlian-Dongwuqi late Paleozoic magmatic belts.
