I need your help now guys.

I'm going to be visiting the Dry Limestone/Basalt veins across the world and updating Basalt to this colour

I'll be starting with the north and working my way down. If you know that a vein is basalt and NOT dry limestone please post it here like this:

Z = 941 - 600/700 (this one I have done already)
