The accessible rock reserves of basalt, anorthosite and carbonates are large enough to supply current human demands for millions of years and can be regarded as inexhaustible resources.
The natural production of carbonate and basalt even overwhelms the consumption in stone wool production. These resources are renewable in the geological sense and can even be regarded as sustainable resources, unless other human activities target these resources.
