Rocky Posted January 25, 2018 Share Posted January 25, 2018 (edited) I'm a meteorite guy who loves collecting interesting stones as well. Every day on my lunch break (30min) I go to the beach and scan the shoreline for cool stones. This Stone was exceptional because it's packed with so much detail, it's beautiful and visibly you can see it's been thru a violent upbringing but I don't know what it is. Any input??

Au Seeker Posted January 25, 2018 Share Posted January 25, 2018 I would say it a breccia, which is shattered rock/mineral cemented back together with fine grain matrix of simliar or totally different material. 2 Quote Link to comment Share on other sites More sharing options...

chrisski Posted January 26, 2018 Share Posted January 26, 2018 I think it may also be metamorphic, perhaps like quartzite. I do think it started out as cemented pediment, but was sucked back under the earth to be recrystallized. With quartzite, one way to tell is that the it will break through the quartz instead of along the boundaries between the cement and the quartz. Just my less then 2 cent thoughts.

4meter Posted January 26, 2018 Share Posted January 26, 2018 I agree with AU Seeker, a Breccia with hematite cement. The clasts look like pieces of gniess but they could be limestone too. Check with a drop of acid or warm vinegar on a few clasts to see if they fizz. Quote Link to comment Share on other sites More sharing options...

Rocky Posted January 29, 2018 Author Share Posted January 29, 2018 Some more shots with close ups for fun. Thanks for the input guys!! I'm glad I found it, it's a pretty sweet rock. Quote Link to comment Share on other sites More sharing options...
Bob(AK) Posted January 30, 2018 Share Posted January 30, 2018 Have found rocks here in Alaska that look identical, same color everything. Also some with green where the reddish brown is. I never did try to figure what it is because I cut and polish and these are soft enough that it will not polish worth a darn. I just looked through some boxes and didn't find any, Bob 1 Quote Link to comment Share on other sites More sharing options...
