Speculations on the formation of cratons and cratonic basins
Earth and Planetary Science Letters, 2016 Surface wave tomography using Rayleigh waves has shown that Tibet and the surrounding mountain ranges that are now being shortened are underlain by thick lithosphere, of simi-\ud lar thickness to that beneath cratons. Both their elevation and lithospheric thickness can result from pure shear shortening of normal thickness continental lithosphere by ...

Building archean cratonic roots [PDF]
Frontiers in Earth Science, 2022 Geophysical, geochemical, and geological investigations have attributed the stable behaviour of Earth’s continents to the presence of their Archean cratonic roots.

Tectonics-mineralisation relationships within weak continental lithospheres: a new structural framework for Precambrian cratons [PDF]
BSGF - Earth Sciences Bulletin, 2018 Many Archaean and Paleoproterozoic cratons show deformation patterns that differ from those observed in modern orogens. On the other hand, they constitute an important part of present-day emerged continents and contain a large part of continental mineral

Channelized metasomatism in Archean cratonic roots as a mechanism of lithospheric refertilization [PDF]
Nature CommunicationsArchean cratons represent stable continental domains which form the nuclei of the Earth’s continents due to their thick ( >200 km), mechanically resistant keels. Cratons and their stable roots form through melt and fluid depletion processes.

Gravity and magnetism of southern Africa in relation to Craton structures and belts [PDF]
HeliyonThe general tectonic structural architecture of southern Africa is an ensemble comprised of Kalahari Craton, a vast range of mosaics of the best-preserved geological Belts, and exposed crustal blocks.

Proterozoic orogenic belts and rifting of Indian cratons: Geophysical constraints [PDF]
, 2014 The Aravalli–Delhi and Satpura Mobile Belts (ADMB and SMB) and the Eastern Ghat Mobile Belt (EGMB) in India form major Proterozoic mobile belts with adjoining cratons and contemporary basins. The most convincing features of the ADMB and the SMB have been

Petrological, mineralogical and geochemical peculiarities of Archaean cratons [PDF]
Chemical Geology, 2019 The most outstanding features of Archaean cratons are their extraordinary thickness and enduring longevity. Seismically, Archaean cratonic fragments are sharply-bounded deep roots of mechanically strong, cold lithospheric mantle, clearly distinguishable ...
