Geologyhound Posted October 6, 2023 Share Posted October 6, 2023 Can it scratch glass? If you put some acid on it (like 0.1 molar hydrochloric acid), does it fizz vigorously or at least produce some bubbles? 1 Link to comment Share on other sites More sharing options...

Geologyhound Posted October 12, 2023 Share Posted October 12, 2023 The last picture shows it has a granular composition. I was thinking quartzite or limestone. The lack of reaction to acid and ability to scratch glass rules out limestone. So, I am thinking it is quartzite. Link to comment Share on other sites More sharing options...
