All the oceanic crust is made of basalt, so approximately 2/3 of the planet is covered by several miles of it. Unfortunately mining oceanic crust is impractical, for obvious reasons. However some oceanic crust got trapped between mountain ranges during continental collision, forming ophiolites. These can be suitable mining sites, together with LIPs (large igneous provinces) and the rocks of some shoshonitic (K-rich) basalt volcanoes. |
