Contrasting accreted terranes in the southern Appalachian Orogen, basement beneath the Atlantic and Gulf Coastal Plains, and West African orogens
TLDR
A variety of lithostratigraphic units may be outlined within the pre-Mesozoic crystalline basement of the Atlantic and Gulf Coastal Plains of the United States, including a group of metamorphic rocks of variable grade together with deformed and retrogressed granite in southwestern Alabama and southeastern Mississippi as mentioned in this paper.About:

The lithospheric architecture of Africa: Seismic tomography, mantle petrology, and tectonic evolution
Graham Begg,William L. Griffin,L. M. Natapov,Suzanne Y. O'Reilly,Stephen P. Grand,Craig O'Neill,Jon Hronsky,Y Poudjom Djomani,Christopher J. Swain,T. Deen,Peter Bowden +10 more
TL;DR: In this paper, the authors present a new analysis of the lithospheric architecture of Africa, and its evolution from ca. 3.6 Ga to the present, using thermal/compositional modeling and xenolith/xenocryst data from volcanic rocks.

Neoproterozoic-early Palaeozoic tectonostratigraphy and palaeogeography of the peri-Gondwanan terranes: Amazonian v. West African connections
R. Damian Nance,J. Brendan Murphy,Rob Strachan,J. Duncan Keppie,Gabriel Gutiérrez-Alonso,Javier Fernández-Suárez,Cecilio Quesada,Ulf Linnemann,Richard D'lemos,Sergei Pisarevsky +9 more
TL;DR: In this article, a collection of peri-Gondwanan terranes are characterized by voluminous late Neoproterozoic arc magmatism and cogenetic basins, and their tectonothermal histories provide fundamental constraints on the palaeocontinental reconstructions for this important period in Earth history.

Extending full-plate tectonic models into deep time: Linking the Neoproterozoic and the Phanerozoic
Andrew Merdith,Simon Williams,Alan S. Collins,Michael G. Tetley,Jacob A. Mulder,Morgan L. Blades,Alexander S. Young,Sheree Armistead,John Cannon,Sabin Zahirovic,R. Dietmar Müller +10 more
TL;DR: For the first time, a continuous full-plate model spanning 1 Ga to the present day was presented in this paper, which includes a revised and improved model for the Neoproterozoic-Cambrian (1000-520 Ma) that connects with models of the Phanerozoic.

Puncoviscana folded belt in northwestern Argentina: testimony of Late Proterozoic Rodinia fragmentation and pre-Gondwana collisional episodes
TL;DR: The earliest synrift igneous products are represented by ultra-potassic dykes and alkaline lava flows of high LREE/HREE and low Zr/Nb-Y/NB ratios as discussed by the authors.
Journal ArticleDOI
A paleogeographical review of the peri- Gondwanan realm of the Appalachian orogen 1
TL;DR: The eastern edge of the Appalachian orogen is composed of a collection of Neoproterozoic-early Paleozoic domains, which are exotic to North America as discussed by the authors.

Paleozoic Base Maps
TL;DR: In this article, the authors present 50 maps which have been designed for use by the geologic community in preparing paleogeographic, biogeographical, climatologic, and tectonic reconstructions of the Paleozoic periods.

TL;DR: In this paper, the authors show that the Brevard fault is the surface expression of an eastward-dipping splay off the main sole thrust, and they show or imply that other major faults of this region have similar origins.
