Structure and extent of the southern African cratons: Integrated images from receiver functions and teleseimic tomography. [PDF]

, 2011
We present a high resolution seismic model of the South African cratonic region from receiver function and telesemic tomography interpretations of the P- and S- body wave data from the South Africa Seismic Experiment (Carlson et al, EOS 77, 1996) across ...

Multi-stage crustal growth and cratonization of the North China Craton

Geoscience Frontiers, 2014
AbstractThe North China Craton (NCC) has a complicated evolutionary history with multi-stage crustal growth, recording nearly all important geological events in the early geotectonic history of the Earth. Our studies propose that the NCC can be divided into six micro-blocks with >∼3.0–3.8 Ga old continental nuclei that are surrounded by Neoarchean ...

GEOCHRONOLOGY (U-Pb) AND ISOTOPE GEOCHEMISTRY (Sr/Sr AND Pb/Pb) APPLIED TO THE VARZEA DO CAPIVARITA METAMORPHIC SUITE, DOM FELICIANO BELT, SOUTHERN BRAZIL: INSIGHTS AND PALEOGEOGRAPHICAL IMPLICATIONS TO WEST GONDWANA EVOLUTION

Geochimica Brasiliensis, 2016
Geochronological and isotope geochemistry analysis on the marbles and pelitic gneisses outcropping in the Várzea do Capivarita Metamorphic Suite in the Dom Feliciano Belt (DFB), southern Brazil, confirms its origin during the agglutination of Congo ...

Thermochemical Structure of the Superior Craton and Environs: Implications for the Evolution and Preservation of Cratonic Lithosphere

Geochemistry, Geophysics, Geosystems
The Archean Superior craton was formed by the assemblage of continental and oceanic terranes at ∼2.6 Ga. The craton is surrounded by multiple Proterozoic mobile belts, including the Paleoproterozoic Trans‐Hudson Orogen which brought together the Superior

Reconciling Seismic and Thermo‐Chemical Models of Cratonic Lithosphere

Geochemistry, 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.

Giant lithium-rich pegmatites in Archean cratons form by remelting refertilised roots of greenstone belts

Communications Earth & Environment
Around 80% of the world’s hard-rock lithium supply comes from pegmatites formed in the Archean Eon, yet our understanding of how Lithium-pegmatites form assumes magma source compositions not relevant to those Archean cratons hosting most of the giant ...
