Although primarily deemed to be an ornamental stone, granite may also ground into fines for use in cement mortars, where it exhibits high strength and durability. Both the 40K present stone natural decay series of its uranium, thorium actinium components exhibit activity concentrations. An understanding is therefore needed correlation among different particle sizes aggregate assess their contri...

In the Bazhenovskoye chrysotile–asbestos deposit (Middle Urals), nephrite bodies of serpentinite type were found on contact after gabbro rodingites and serpentinites. The color is uniform to non-uniform, green light green, bluish greyish whitish. Spots, streaks, lenticules bright bluish-green or, contrary, are sometimes noted. mostly comprised tremolite. Chromite decreases quality ornamental st...
