Basalt ( UK: / ˈbæsɔːlt,-əlt /; [1] US: / bəˈsɔːlt, ˈbeɪsɔːlt /) [2] is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low- viscosity lava rich in magnesium and iron ( mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt.

· The biggest obstacle to mine safety – the reason so many miners die at work – is profit. It is entirely possible to process mine tailings safely, but it costs more. Mines can be reinforced to prevent collapse, but this takes time. Safety is expensive, and would make some marginal mines uneconomic.
