Volcanicity was violent during the Early Carboniferous in Santanghu region.The volcanic rocks consist of basalts,andesites and dacite liparite,with andesites playing the main part.

“One lesson is that these volcanoes in the Canary Islands behave a little bit differently from other basaltic volcanoes we commonly see in the media for example, like Hawaiian volcanoes and Etna in Italy.”
So they'll take that CO2, mix it with water and inject it deep underground where it will react with a rock formation underground that's made of basalt.
These dust devils have been seen from orbit, and when they blow the red dust around on the greyish basaltic plains, they can leave behind incredibly complex and beautiful curlicues.
Fresh from the interior of a planet, magma usually forms a blackish rock called basalt—not granite, says planetary geoscientist Harry McSween of the University of Tennessee.
