Fulgurite (from Latin fulgur,'ray')is a tube of lechatelierite (vitricized silica)that can be found in sands or sandstones and which is the result of the fall of an atmospheric ray.
The fall of the ray on sandy terrain causes the melting of silica grains,since the temperature of the silica can reach 4000 degrees Celsius and up to a depth of more than one meter, but in a very narrow area. Silica is thus vitriified in the form of lightning tubes,2 to 50 mm in diameter, sometimes twisted or branched. These fulguritas abound in the sand deserts and in the coastal dunes.
