Anv的Shrimp离子探针分析用来测量加拿大Saskatchewen trors Hudson造山带驯鹿湖带哈得孙沉积岩中碎屑锆石的U-Pb同位素年龄。在该区,好几个岩性构造带由镁铁质到长英质变质火山岩、变质沉积岩组成,花岗质岩体成线状平行于北西侧的churdiu陆台分布(Van Schumus等人1987)。驯鹿湖带内的锆石U-Pb同位素年龄处于1.84～1.89Ga之间,而Churchiu陆台的同位素年龄在2.5～3.0Ga之上。对驯鹿湖带的火山岩、沉积岩和花岗质岩石的Nd同位素分析得出,∈_(Nd)(时间为1.9Ga)在+5到-8之间,其中较高的值来自于远离churchiu陆台以变质火山岩为主的带中;较低的值来自于与Churchiu陆台相邻的片麻岩和混合岩带内(Chaurvell等人,1987),从三个带用的变质沉积岩中新测定的Nd同位素得出∈_(Nd)值在+4到-2之间,而Nd
Anv’s Shrimp ion probe analysis was used to measure the U-Pb isotopic ages of detrital zircons in the Hudsonian sediments from the Saskatchewan trough Hudson ordeal in Canada. In this area, several lithologic tectonic belts consist of mafic-to-metamorphic metasedimentary metamorphic sedimentary rocks that are linearly parallel to the churdiu terrestrial distribution on the northwestern side (Van Schumus et al., 1987) . The zircon U-Pb isotope age in the reindeer-lake zone ranges from 1.84 to 1.89 Ga, while the age of the Churchiu continental platform is 2.5 to 3.0 Ga. The Nd isotopic analysis of volcanic rocks, sedimentary rocks and granitic rocks in the Caribou Lagoon shows that ∈ Nd (1.9Ga) is between +5 and -8, with the higher values coming from the land far away from the churchiu Taiwan metamorphic volcanic rocks; the lower values come from the gneisses and mixed rocks adjacent to the Churchiu station (Chaurvell et al., 1987), newly determined from the three metamorphic sedimentary rocks Nd isotopes give ∈_ (Nd) values between +4 and -2, whereas Nd
