Origin and Geology of Basalt

The adjacent graphic from the University of Kassel shows the structure of the earth's layers and the basalt deposits that - along with granite - make up the earth's crust, which is 5 to 50 km thick.

Basalt rock for the production of fibers is commercially mined mainly in Russia and China, but also in Ukraine and Georgia.

The production of basalt fibers (spinning process) also takes place in these countries.
