摘要
从建造组合分析 ,划分开合序列 ,分析新疆地壳演化的原始大陆、古大陆、新大陆三大开合演化阶段 ,重点阐述古大陆开合演化阶段的四个开合旋回 ,提出新疆开合构造的四种类型。总结新疆开合构造多旋回发展 ,此开彼合、有序南移的活动特点 ,联系成矿作用 。
By analysis of formation associations the opening- closing series are subdivided and three open- ing- closing stages of the crustal evolution are analyzed including proto- continent,paleo- continent and neo- continent stages.Four opening- closing cycles are described by emphasis of the paleo- continent stage,and four types of opening- closing tectonics are put forward in Xinjiang.The features of opening- closing tectonics of Xinjiang are summarized,covering polycyclic development,opening and closing by the meantime,and southward migration in order.Finally point out that different types of opening- closing own different minerals and metallogenic series.
