摘要：

Quartz is an important component of the Earth. In this study, experiments were conducted at temperatures between 600 to 700 degrees C, confining pressures between 1.5 and 1.8 GPa, and differential stress conditions. It was found that coesite production is closely related to differential stress, reaction time, and reaction temperature, with coesite formation being a multifactorial coupling process.
