Rocky Posted July 12, 2017 Share Posted July 12, 2017 Hi, I found this rock awhile ago, it was just to cool to not pick up. Any ideas what it might be. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Rocky Posted July 12, 2017 Author Share Posted July 12, 2017 I found this on a beach in Cape Cod if I remember correctly, the only other place I could have found it was in one off the conservation paths here on Cape Cod as well. Quote Link to comment Share on other sites More sharing options...

Haderly Posted July 13, 2017 Share Posted July 13, 2017 Two that come to mind is oolite limestone or variolite. I am not familiar with that area so both guesses could be wrong. Can you let if the dark spot are crystals...any transparency to them? Quote Link to comment Share on other sites More sharing options...

There is no transparency and they don't appear to be crystals.The surface texture under magnification is say smudged smooth and characterless, maybe from beach erosion. Should I consider trying to maybe file and polish a side, and make more macro shots?? Quote Link to comment Share on other sites More sharing options...
