Kiwi_bird Posted April 7, 2020 Share Posted April 7, 2020 Hello all! I am a new member, and this is my first post. Could I please have some help figuring out if these rocks are petrified wood? Most of them were found in a small Pennsylvanian stream. It looks like they are quartz, crystal quartz, but I am no expert. There should be about two pictures of each rock. Thanks for your help, and I have more pictures of different rocks if needed. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted April 7, 2020 Share Posted April 7, 2020 Some of the later ones, at least, look like calcite. Do they fizz slightly when vinegar is applied to a clean section? Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

digit Posted April 7, 2020 Share Posted April 7, 2020 Yup. Links are already not allowing me to see the images. You can still go back and edit your post to attach the images directly to the message. Cheers. -Ken 4 Link to comment Share on other sites More sharing options...

Ludwigia Posted April 9, 2020 Share Posted April 9, 2020 Can you please be more precise about the location of that small Pennsylvanian stream? Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
