ABSTRACT Deep crustal fragments and structural lineaments identified through satellite gravity data provide evidence for the extension of the reworked ancient basement of the Central African Block into the northern São Francisco Craton and southern Borborema Province.

ABSTRACT The Transbrasiliano‐Kandi‐4°50′ (TK4) shear zone in western Gondwana crosscuts South America and NW Africa for at least 6000 km. Despite its impressive size, the timing of the main episode of dextral ductile shearing is uncertain. We present detailed in situ multi‐mineral geochronology of mylonites from both Brazil and Algeria supporting that ...

Analysis of a century of (evolutionary) socio-economic transition in the British Caribbean. According to the author, this process demonstrated aspects of a continuum, rather than sharply marked phases and abrupt changes.

We used teleseismic Rayleigh waves recorded by three recent broadband seismic arrays in southern Australia to develop a shear wave velocity model of the South Australian Craton from the lower crust to 250 km depth and compare this with isotope data ...

COACH CV: The Seven Clinical Phenotypes of Concussion
Our understanding of the diverse physiological manifestations of concussion is changing rapidly. This has an influence on the clinical assessment of patients who have sustained a concussion. The 2017 Consensus Statement on Concussion in Sport states that

Episodic crustal growth in the Tanzania Craton: evidence from Nd isotope compositions
: The analysis of available Nd isotope data from the Tanzania Craton places important constraints on the crust-mantle separation ages, and events marking juvenile crustal addition and crustal recycling. Nd model ages date the oldest crust extraction to 3.

Essence of the Late Mesozoic ore-magmatic systems of Aldan Shield
The original cause of the Late Mesozoic tectonic-magmatic and mineragenic activation at the Pre-Cambrian Aldan Shield was the existence of the stagnated oceanic slab in the mantle transitional zone.
