What are cratons and greenstone belts? As mentioned elsewhere, through the process of differentiation the earth is sorting itself by density: the heavy stuff is sinking towards the core and the lighter stuff is accumulating at the surface, kind of like scum.. A craton is a continent-sized "raft" of low density felsic rock (commonly granite) which has been purified by the earth and accumulated ...

Greenstone is de verzamelnaam van verschillende soorten mineralen en stenen. Op ongeveer 10 km. diep in de aarde zit een laag van vulkanisch materiaal waarin allemaal chemische reacties plaatsvinden. Dit wordt de greenstone belt genoemd. Een Greenstone belt is een geologische zone van een kraton.

2-7-2020 · Greenstone belt. Greenstone belts are generally elongate, Archean to Proterozoic terrains comprising intrusive and extrusive mafic to ultramafic igneous rocks, felsic volcanics, and inter-flow or cover sedimentary rocks. Greenstone belts occur sandwiched between regions dominated by granitoids and gneiss.Greenstones are generally of low to moderate metamorphic grade.

After a century of virtual neglect, exploration in the Yandal greenstone belt of the Yilgarn Craton of Western Australia has yielded resources of 12 Moz Au during the 1990s. Success has come from a combination of conceptual geological models, surface prospecting, understanding the weathering environment, and systematic drilling. The Archaean Yandal greenstone belt comprises a lowermost .
