Here is a great looking world map which shows the distribution of continental basalts (a) and ophiolite complexes (b). Ophiolites are slices of the earth' s oceanic crust and upper mantle that have been exposed on land by tectonic forces. They are found along ancient and modern convergent plate settings i.e. regions where two plates are converging and colliding with each other.
Can these mafic igneous rocks act as reservoirs for storing carbon dioxide?

The article is open access. I posted about this article before but more from the perspective of the Deccan Basalts as a potential CO2 reservoir and how that might conflict with other more immediate uses of that rock body.
I thought I'd pass along the link to this map too.
