Abstract
Experiments have been carried out to determine the effect of pressure and temperature on the rate of formation of quartz from silicic acid. The rate is much more sensitive to pressure than temperature and this is discussed in terms of possible mechanisms. Cristo-balite and silica-K appear as intermediate phases before quartz is formed in appreciable quantity. In this system increasing pressure favours the attainment of equilibrium more than increasing temperature.
