Plume

Description

Limited Edition Reproduction of 100 Only

By 130 million years ago South America and Africa were attempting to separate. Their fractured, crystalline cratons or continental shields (pink) had been locked together with their intervening mountain chains (dark blue) for hundreds of millions of years.  Across present-day central Africa and Brazil there was a Central West Gondwana Basin ‘Sahara-like” paleo-desert containing dunes of wind blown sand (red-brown). A mantle plume (orange and yellow) had broken the earth’s crust and was spewing out volcanic lava. The lava and wind blown sand were sometimes intercalated.
