@shasta brought me here. Awesome photos and now following.

Top one looks like a volcanic breccia. Pretty cool. Bottom looks like a iron or maganese nodules.

Feel free to stop by the Nature Identification Contest sometime on my blog @snowyknight if you have other natural world things you would like help with.

Cheers!

Thank you very much. That’s very kind of you. I am so glad to know more about these rocks! I had a feeling they were special even though they didn’t look beautiful or luxurious like sparkling crystals.

Thanks for your support.
