Geosystems and Geoenvironment, 2022 Cratons are the stable portions of the continents for at least the past two billion years. Their longevity is generally attributed to their thick, cold, rheologically strong and chemically depleted subcrustal mantle lithosphere.

Seismic Evidence for Craton Formation by Underplating and Development of the MLD
Geophysical Research LettersInconsistencies between observations from long and short period seismic waves and geochemical data mean craton formation and evolution remains enigmatic. Specifically, internal layering and radial anisotropy are poorly constrained.

Proterozoic paleogeographic evolution of South American cratons [PDF]
, 2008 The South American platform is composed of four major cratons (Amazonian, São Francisco, Rio de la Plata and São Luis) and other smaller continental blocks and terrains that may have taken part in supercontinental assemblages.

Rifts, orogens, cratons, and global tectonics: Introduction
Геодинамика и тектонофизика, 2017 A key role in developing the Earth theory is played by comparative studies of orogens, rifts, and platforms in the equatorial, middle and high latitudes of Asia and the adjacent Arctic regions.

African cratonic lithosphere carved by mantle plumes
Nature Communications, 2020 Cratons represent the ancient cores of continental plates and are generally thought to have been stable since the Archean. Here however, the authors combine seismic analysis with kimberlite data to infer complete destruction of cratonic lithosphere in ...

A comparative study of parameterized and full thermal-convection models in the interpretation of heat flow from cratons and mobile belts [PDF]
, 1993 Heat flow from Archean cratons worldwide is typically lower than from younger mobile belts surrounding them. The contrast in heat flow between cratons and mobile belts has been attributed in previous studies to the greater thermal resistance of thicker ...

Age-dependent seismic thickness and mechanical strength of the Australian lithosphere [PDF]
, 2002 We present constraints on the regional variations of the seismic and mechanical thickness of the Australian lithosphere. We infer the seismic thickness from a waveform tomographic model of S-wave speed, and as a proxy for the elastic thickness we use the

, 2017 The Damara Orogen is composed of the Damara, Kaoko and Gariep belts developed during the Neoproterozoic Pan-African Orogeny. The Damara Belt contains Neoproterozoic siliciclastic and carbonate successions of the Damara Supergroup that record rift to ...
