The Archean Huangling greenstone belt (HGB) is preserved as amphibolites in the Huangling granite–greenstone terrane, Yangtze Craton. Geologically and geochemically, the amphibolites are metavolcanic rocks and can be subdivided into amphibole schist, massive amphibolite and banded amphibolite, with komatiite, komatiitic basalt and tholeiitic basalt protoliths, respectively....

Greenstone belts: primordial tectonics – Historical Geology

The greenstone belts are typically sandwiched between large bodies of crustal rocks such as granite and gneiss. Not all greenstone belts are Archean; some are also known from the Proterozoic. But the Proterozoic''s tectonic record is more diverse, so for the sake of …...

On the nature of greenstone belts in the precambrian ...

At present there is considerable speculation concerning the origin of greenstone belts. They are compared with Phanerozoic geosynclines, fold belts, modern island arcs or with the rift structures formed above subduction zones in marginal seas. Four stages in greenstone-belt development can be determined (3.8-3.0, 3.0-2.6, 2.6-1.9 and 1.9 b.y. and younger)....
