Kimberlite

Rapid mining led to the kimberlite being mined-out and the mine closed by 1914 This means that no modern geological investigations were ever carried-out on probably the "archetypical" kimberlite Maps of the mine show that it had a pipe-like shape and that it probably consisted of diatreme-facies kimberlite (Clement 1982) Get price
