Experiments with copper minerals at high temperatures.

Some copper sulphide minerals recrystallized when heated in a temperature gradient in an argon-sulphur atmosphere, and acicular and lenticular crystals grew down gradient. The crystal composition was determined by the composition of the starting material, temperature, and the sulphur vapour pressure...
