TLDR
In this paper, the authors explain the Variscan orogen in a two-plate scenario, reasoning that the complexity of the orogen (multitude of high-grade metamorphic belts, compositional diversity of coeval magmatism, and arrangement of foreland basins) is the result of the distribution of crustal domains of contrasting rheological properties.About:

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.
Journal ArticleDOI
The Palaeozoic Variscan oceans revisited
TL;DR: In this article, the existence of three Gondwana-derived microcontinents which were involved in the Variscan collision is confirmed, supported by biogeographical data and in accord with palaeomagnetic constraints.

Phanerozoic tin and tungsten mineralization—Tectonic controls on the distribution of enriched protoliths and heat sources for crustal melting
Rolf L. Romer,Uwe Kroner +1 more
TL;DR: In this paper, the formation of these belts is explained by a generic process, involving three independent steps as prerequisite for the development of deposits: (i) intense chemical weathering of sedimentary rocks on a stable continent resulting in the enrichment of Sn and W in the protoliths, (ii) sedimentary-followed by tectonic-accumulation of the enriched debris at continent margins, and (iii) heating of the voluminous sedimentary protoliss generating Sn and/or W enriched melts.

Arc-continent collisions in the tropics set Earth's climate state.
Francis A. Macdonald,Nicholas L. Swanson-Hysell,Yuem Park,Lorraine E. Lisiecki,Oliver Jagoutz +4 more
TL;DR: A database of Phanerozoic arc-continent collisions and the latitudinal distribution of ice sheets was compiled, showing that ice coverage was greatest when those collisions were most widespread, maximizing global weatherability.
Journal ArticleDOI
Four billion years of ophiolites reveal secular trends in oceanic crust formation
TL;DR: In this article, the authors combine a geological, geochemical and tectonic dataset from 118 ophiolite complexes of the major global Phanerozoic orogenic belts with similar datasets of Ophiolites from 111 Precambrian greenstone belts to construct an overview of oceanic crust generation over 4 billion years.

Effect of recent revisions to the geomagnetic reversal time scale on estimates of current plate motions
TL;DR: In this article, the optimal recalibration of NUVEL-1 is proposed to multiply the angular velocities by a constant, α, of 0.9562, which is a compromise among slightly different calibrations appropriate for slow, medium, and fast rates of seafloor spreading.
Journal ArticleDOI
Evolution of the Altaid tectonic collage and Palaeozoic crustal growth in Eurasia
TL;DR: A new tectonic model, postulating the growth of giant subduction-accretion complexes along a single magmatic arc now found contorted between Siberia and Baltica, shows that Asia grew by 5.3 million square kilometres during the Palaeozoic era as mentioned in this paper.
Journal ArticleDOI
A plate tectonic model for the Paleozoic and Mesozoic constrained by dynamic plate boundaries and restored synthetic oceanic isochrons
TL;DR: In this article, a plate tectonic model for the Paleozoic and Mesozoic (Ordovician to Cretaceous) integrating dynamic plate boundaries, plate buoyancy, ocean spreading rates and major Tectonic and magmatic events was developed.

TL;DR: In this article, the authors present and interpret GPS measurements of crustal motions for the period 1988-1997 at 189 sites extending east-west from the Caucasus mountains to the Adriatic Sea and north-south from the southern edge of the Eurasian plate to the northern edge of Africa.
