Because quartz is relatively stable at surface temperatures and pressures, it can be concentrated by weathering processes to be even more abundant in sedimentary rocks than it is in igneous rocks. Quartz sand grains are a significant component of most sandstones and siltstones, and some detrital sedimentary rocks are almost exclusively composed ...

The rock formation process takes place during mountain-building events at convergent plate boundaries. Quartzite forms when quartz-rich sandstone (a sedimentary rock) is changed by metamorphism. The heat, pressure, and chemical activity are applied to recrystallize the sand grains and silica cement.
