蒙古国南戈壁Harshatewula地区二长花岗岩LA-ICP-MS锆石U-Pb年龄及其地质意义
LA-ICP-MS zir-con U-Pb dating of monzogranite of Harshatewula area in South Gobi province, Mongolia, and its geological significance
摘要
Abstract
High precision LA-ICP-MS zircon U-Pb dating of the Harshatewula monzogranites was conducted. The analyses indi⁃cate that the intrusion was formed at 327.0±2.1Ma, belonging to Early Carboniferous. The age is a relatively reliable and directly mea⁃sured datum which provides the evidence for the existence of an island arc magmatite belt composed of Beishan tectonic belt, Har⁃like-Dananhu islandarc belt and Gobi-Tianshan island arc magmatite belt. This result has great significance for the understanding of the tectonic-geological evolution in this area.关键词
