In geology most text books describe crystals or rock formation as the result of time , pressure and temperature. Although not what temperature, time or pressure that is. I have seen crystals form at room temperature over weeks at 1 bar. Is the variety so great that to give numbers unreasonable. Does anyone know at what T-P-T feldspar would form crystals
