Terrestrial specificity, the crust of our Planet is divided into numerous tectonic plateswho have the ability to moveunder the impetus of the convection mantle and major tectonic processes: accretion oceanic…
Granulite: what is it?
A granulite is a metamorphic rock formed under average conditions pressure and high temperature. Granulites are also used to define a facies high degree metamorphic. the metamorphism of the granulite…
The formation of supermountains would have impacted the evolution of life on Earth
By tracking zircons with a low lutetium content, Australian researchers have succeeded in identifying the formation, during the history of the Earth, of two “supermountains” rising more than 8 km…
The formation of diamonds is linked to the great tectonic cycles
Diamonds are formed in the bowels of the Earth, at very great depth and high temperature. They rise to the surface through volcanic eruptions. They are thus found prisoners of…
This map betrays the magnetic signatures of the telluric forces that shaped the Earth
The map of the Earth’s magnetic field has been enriched with a new model making it possible to better understand the thermal state of the Earth’s crust, to perceive the…
