Physical properties
Pale gray-beige, fine-grained and matte, with a rounded, smoothed shape; quartz hardness is 7 Mohs. The image does not show enough detail to confirm mineral grains or cleavage.
Formation & geological history
If quartzite, it formed when quartz-rich sandstone was recrystallized by heat and pressure; such rocks occur in many geological eras. Its rounded shape likely reflects abrasion during transport or tumbling.
Uses & applications
Quartzite is used as aggregate, paving and building stone, and sometimes as decorative stone; this small piece appears to have little commercial value.
Geological facts
The photograph alone cannot reliably distinguish quartzite from other pale, fine-grained stones such as limestone or concrete-like manufactured material.
Field identification & locations
A fresh broken surface, visible interlocking quartz grains, and lack of fizz with dilute acid help distinguish quartzite from limestone; the pictured smooth, pale pebble is not enough for a firm identification.
