The Gondwana supercontinent was an accretion of several cratons from different landmasses, namely South America, Antarctica, Africa, Madagascar, Australia, and the Indian subcontinent.

Crustal Groundwater Volumes Greater Than Previously Thought
Global groundwater volumes in the upper 2 km of the Earth's continental crust—critical for water security—are well estimated. Beyond these depths, a vast body of largely saline and non‐potable groundwater exists down to at least 10 km—a volume that has ...

Criteries and prospects of diamonds of the Vitebsk granulite massif
The article describes the history of studying the diamond content of tectonic structures of the territory of Belarus. Based on the results of magnetometric, mineralogical, tectonic studies carried out by industrial geologists and scientists over the past

Mountain roots and the survival of cratons [PDF]
In the last few years, evidence from the apparently unconnected fields of earthquake seismology, gravity, geochemistry, rock mechanics,mineralogy and petrology has come together to provide simple insights into the fundamental geological questions: why ...

Titanium and iron isotopic records of granitoid crust production in diverse Archean cratons [PDF]
Archean granitoid provides critical clues on how Earth's felsic crust was established and its geodynamics evolved. In this study, we present Fe-Ti isotope and trace-element data for granitoids (mostly TTGs) from the ∼3.8-3.6 Ga Itsaq Gneiss Complex and ...

Understanding the dynamics and evolution of cratons [PDF]
The earth is the only rocky planet in the solar system that exhibits plate tectonics. One of the basic tenets of plate-tectonics is that it recycles the lithosphere within a few hundred million years.

A Thermo‐Compositional Model of the African Cratonic Lithosphere
Recently, the continually increasing availability of seismic data has allowed high‐resolution imaging of lithospheric structure beneath the African cratons.

Dynamic Cause of Marginal Lithospheric Thinning and Implications for Craton Destruction: A Comparison of the North China, Superior and Yilgarn Cratons [PDF]
We present a comparative tectonic analysis of the North China craton (NCC), which has lost parts of its root, with the Yilgarn and Superior cratons, which preserve their roots.

Kyanite-bearing eclogite xenoliths from the Udachnaya kimberlite, Siberian craton, Russia [PDF]
Xenoliths brought up by kimberlite magmas are rare samples of otherwise inaccessible lithospheric mantle. Eclogite xenoliths are found in most cratons and commonly show a range of mineral and chemical compositions that can be used to better understand ...

The stability of cratons is controlled by lithospheric thickness, as evidenced by Rb-Sr overprint ages in granitoids [PDF]
International audienceThe ancient cores of modern continents, cratons, are the oldest blocks of "stable" lithosphere on Earth. Their long-term survival relies on the resistance of their underlying thick, strong, and buoyant mantle keels to subsequent ...
