| Abstract: | 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. |
