TLDR
In this paper, a model for the late Paleozoic (410-250 million years ago) is presented, together with a review of the underlying data, which can be used for numerical mantle modeling, and serve as a general framework for understanding late paleozoic tectonics.Abstract:
As the chronicle of plate motions through time, paleogeography is fundamental to our understanding of plate tectonics and its role in shaping the geology of the present-day. To properly appreciate the history of tectonics—and its influence on the deep Earth and climate—it is imperative to seek an accurate and global model of paleogeography. However, owing to the incessant loss of oceanic lithosphere through subduction, the paleogeographic reconstruction of ‘full-plates’ (including oceanic lithosphere) becomes increasingly challenging with age. Prior to 150 Ma ∼60% of the lithosphere is missing and reconstructions are developed without explicit regard for oceanic lithosphere or plate tectonic principles; in effect, reflecting the earlier mobilistic paradigm of continental drift. Although these ‘continental’ reconstructions have been immensely useful, the next-generation of mantle models requires global plate kinematic descriptions with full-plate reconstructions. Moreover, in disregarding (or only loosely applying) plate tectonic rules, continental reconstructions fail to take advantage of a wealth of additional information in the form of practical constraints. Following a series of new developments, both in geodynamic theory and analytical tools, it is now feasible to construct full-plate models that lend themselves to testing by the wider Earth-science community. Such a model is presented here for the late Paleozoic (410–250 Ma) together with a review of the underlying data. Although we expect this model to be particularly useful for numerical mantle modeling, we hope that it will also serve as a general framework for understanding late Paleozoic tectonics, one on which future improvements can be built and further tested.read more

A Tale of Amalgamation of Three Permo-Triassic Collage Systems in Central Asia: Oroclines, Sutures, and Terminal Accretion
Wenjiao Xiao,Brian F. Windley,Shu Sun,Jiliang Li,Baochun Huang,Chunming Han,Chao Yuan,Min Sun,Hanlin Chen +8 more
TL;DR: The Central Asian Orogenic Belt as discussed by the authors records the accretion and convergence of three collage systems that were finally rotated into two major oroclines, the Mongolia collage system was a long, N-S-oriented composite ribbon that was rotated to its current orientation when the Mongol-Okhotsk orogine was formed.

Closure of the Proto-Tethys Ocean and Early Paleozoic amalgamation of microcontinental blocks in East Asia
Sanzhong Li,Shujuan Zhao,Xin Liu,Huahua Cao,Shan Yu,Xiyao Li,Ian D. Somerville,Shengyao Yu,Yanhui Suo +8 more
TL;DR: In this paper, the Proto-Tethys Ocean is defined as a complex complex paleo-ocean located between the Tarim-North China and the Sibumasu/Baoshan blocks, and it was opened from the rifting of the Supercontinent Rodinia and mainly closed at the end of the Early Paleozoic.

Tectonic models for accretion of the Central Asian Orogenic Belt
TL;DR: The Central Asian Orogenic Belt ( c. 1000-250 Ma) formed by accretion of island arcs, ophiolites, oceanic islands, seamounts, accretionary wedges, and oceanic plateaux and microcontinents in a manner comparable with that of circum-Pacific Mesozoic-Cenozoic orogens is studied in this article.
