Formation and evolution of the Archean continental crust of China: A review

open access: yesChina Geology, 2018
: The mainland of China is composed of the North China Craton, the South China Craton, the Tarim Craton and other young orogenic belts. Amongst the three cratons, the North China Craton has been studied most and noted for its widely-distributed Archean ...

Palaeoproterozoic assembly of the São Francisco craton, SE Brazil : new insights from U–Pb titanite and monazite dating.

open access: yes, 2017
Isotopic U–Pb titanite and monazite data from the southern Sao Francisco craton better constrain the timing of the tectono-thermal event that led to the amalgamation of the craton and the crust that forms the basement of its fringing orogenic belts in ...

Craton Destruction 1: Cratonic Keel Delamination Along a Weak Midlithospheric Discontinuity Layer

open access: yesJournal of Geophysical Research: Solid Earth, 2018
Cratons are generally observed to retain thick (>180 km) conductive keels for billions of years. However, some cratons have undergone keel removal, with well‐documented examples being the eastern North China Craton (NCC) and the Wyoming Craton (WC ...

DEEP STRUCTURE OF THE SIBERIAN PLATFORM – CENTRAL ASIAN MOBILE BELT TRANSITION ZONE FROM TELESEISMIC DATA

open access: yesГеодинамика и тектонофизика, 2016
Deep velocity sections of the transition zone from the Siberian platform to the Central Asian mobile belt are constructed by teleseismic tomography and P-receiver function techniques.

Exploring the Gravimetric and Geochronological Links in Ancient Terranes of the São Francisco Craton and Borborema Province, NE‐Brazil

open access: yesTerra Nova, Volume 38, Issue 2, Page 77-86, April 2026.
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.

Near‐Synchronous Cambrian Evolution of the Transbrasiliano‐Kandi‐4°50′ Shear Zone in South America and Africa

open access: yesTerra Nova, Volume 38, Issue 2, Page 97-105, April 2026.
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 ...

Reconciling Seismic and Thermo‐Chemical Models of Cratonic Lithosphere

open access: yesGeochemistry, Geophysics, Geosystems
Most published global and regional shear‐wave (VS) velocity models of cratons include a VS increase with depth below the Moho, with a maximum at 100–150 km depth.

Magmatic underplating associated with Proterozoic basin formation: insights from gravity study over the southern margin of the Bundelkhand Craton, India [PDF]

open access: yesSolid Earth
Extension tectonics responsible for intracratonic rift basin formation are often the consequences of active or passive tectonic regimes. The present work puts forth a plume-related rifting mechanism for the creation and evolution of two Proterozoic ...
