Abstract

Hydrothermal melting reactions in the system NaAlSiO_4-SiO_2-H_2O have been extended into the coesite stability field using piston-cylinder apparatus, and the quartz-coesite transition has been bracketed at 735° (28.0±0.9 Kb) and at 800° C (28.15±0.9 Kb) in the presence of a silicate liquid phase; this provided favorable kinetic conditions. The results agree closely with previous piston-cylinder determinations employing a correction for pressure loss due to friction. Consideration of previous calibration and hysteresis experiments leads to the conclusion that despite its potential utility, the quartz-coesite transition can not be confidently used as a calibrant for piston-cylinder apparatus until the question of whether or not to apply a friction correction has been resolved.
