Basalt is a finely grained stone
Basalt is a finely grained stone with a ten times greater tensile strength than steel, a three time greater elasticity modules than steel, is nearly as hard as diamonds, is non-corrosive, and can be extruded into micro-thin fibers in the range of ten microns for the production of almost anything, including the production of large scale woven arteries for conveying the outflow of large rivers across the oceans to wherever fresh water is needed, and so on.
