摘要
何国琦教授将裴伟等的显生宙地壳发展成熟度理论的三阶段(洋壳—过渡壳—陆壳)模式发展为五阶段(老陆壳—拉张型过渡壳—洋壳—汇聚型过渡壳—新陆壳)模式.本文按此模式讨论了新疆北部地壳发展各阶段的岩浆建造及其成矿作用,并进一步将新陆壳阶段划分出固结期.活化期、稳定期.
The theory of the development maturity of Earth's crust by Peve et al divided the evolution of the phanerozoic crust into three stages: oceanic-transitional-conti- nental. This theory was developed by He Guoqi. He divided it into five stages: old continental crust-tensile transitional crust-oceanic crust-convergent crust-phanero-zoic new continental crust. According to this model, this paper describes the mag-matic formation and the mineralization of the northern Xinjiang.
