The Tasmanides occupy the eastern third of Australia and provide an extensive record of the evolution of the eastern Gondwanan convergent plate boundary from the Cambrian to the Triassic. This article presents a summary of the primary building blocks (igneous provinces and sedimentary basins) within the Tasmanides, followed by a discussion of the timing and extent of deformation events. Relatively short episodes of contractional deformation alternated with longer periods of crustal extension accompanied by voluminous magmatism. This behavior was likely controlled by plate boundary migration (trench retreat and advance) that was also responsible for bending and segmentation of the convergent plate margin. As a result, the Tasmanides were subjected to at least three major phases of oroclinal bending, in the Silurian, Devonian, and Permian. The most significant segmentation likely occurred at ∼420–400 Ma along a lithospheric-scale boundary that separated the northern and southern parts of the Tasmanides. Exp...

Tasmanides：澳大利亚东部的显生宙构造演化

Tasmanides 占据了澳大利亚东部的三分之一，并提供了从寒武纪到三叠纪的东部冈瓦纳会聚板块边界演化的广泛记录。本文概述了塔斯马尼德地区的主要组成部分（火成岩省和沉积盆地），然后讨论了变形事件的时间和范围。相对较短的收缩变形事件与伴随大量岩浆作用的较长时间的地壳伸展交替出现。这种行为可能是由板块边界迁移（海沟后退和前进）控制的，这也是会聚板块边缘弯曲和分割的原因。结果，塔斯马尼德群岛至少经历了志留纪、泥盆纪和二叠纪三个主要的口斜弯曲阶段。最重要的分割可能发生在大约 420-400 Ma 沿岩石圈尺度边界，该边界将塔斯曼尼德山脉的北部和南部分开。经验...
