Figure 15-22 displays the phase diagram of carbon, showing the ranges of temperature and pressure in which carbon will crystallize either as diamond or graphite. What is the minimum depth at which diamonds can form if the local temperature is 1000°C and the subsurface rocks have density 3.1 g/cm 3 , Assume that, as in a fluid, the pressure is due to the weight of material lying above.
