TL;DR: The age relations for assembly of Gondwana and Pangea indicate that the timing of collisional orogenesis between amalgamating continental bodies was synchronous with subduction initiation and contractional orogens within accretionary orogens located along the margins of these supercontinents as mentioned in this paper.

TL;DR: The Bayankhongor ophiolite is interpreted to mark the collisional suture between the Baidrag and Hangai continental blocks in Central Asia as discussed by the authors, and it has been shown that the mechanism of Palaeozoic continental growth was by subduction-accretion with punctuated collisions that produced ophiolaitic sutures between accreted blocks.

TL;DR: In this article, panchromatic and wavelength cathodoluminescence (CL) was combined with quantitative rare earth element (REE) ion microprobe analyses to demonstrate modification of zircon REE chemistry within the areas of crystal plasticity.

TL;DR: In this article, the authors report new U-Pb Secondary Ion Mass Spectrometry (SIMS) data from the oldest known eclogites (the ∼2.0 Ga Usagaran eclogs, Tanzania) that constrain the timing of high-grade metamorphism, deformation and exhumation of these e clogites and constrain speed of these processes.

TL;DR: A micro-probe analysis of detrital zircons and whole-rock analysis of two early Palaeozoic low-grade metasedimentary units record the early evolution of this region.
