InsectariumPlus Posted December 23, 2015 Share Posted December 23, 2015 I've found this piece of rock some long time ago while searching for marine fossils of the Oligocene. Sometimes I think it's a piece of concrete with other small stones sticked to it but the place where it was found had no constructions around. Any idea?

Raggedy Man Posted December 24, 2015 Share Posted December 24, 2015 (edited) Looks like a conglomerate with volcanic tekkites. Is there a known meteorite impact site near where you found this? Location of the find would help greatly for this and for any future posts. Edited December 24, 2015 by Raggedy Man ...I'm back. Link to comment Share on other sites More sharing options...
sTamprockcoin Posted December 24, 2015 Share Posted December 24, 2015 Looks pretty well water tumbled. Could just be a piece of cement that has tumbled a long distance from its construction source. I'd agree that it appears volcanic in origin. The black and clear "bits" may either sands incorporated into a cooling lava or minerals that "grew" in the vugs as the host lava cooled. I'd break one each of the bits and go through the standard mineral ID tests (hardness, fracture, cleavage, crystal structure, acid tests). Research minerals associated with volcanic flows. Be wary of anyone who jumps straight to "Meteor" origins. The only guys more "enthusiastic" than meteor hunters (if I had a 1$ for every pound of iron furnace slag that just had to be a meteorite, I'd never have to work another day in my life!) about seeing as what they want are the gold panners, who have fierce competition from indian artifact hunters. “Beautiful is what we see.

ynot Posted December 24, 2015 Share Posted December 24, 2015 I think that it looks like it is volcanic in origin, but it could be a sedimentary conglomerate also. Location would help. Tony Link to comment Share on other sites More sharing options...
Tennessees Pride Posted December 28, 2015 Share Posted December 28, 2015 I agree w/ other members, the specimen could have a volcanic origin. Also wanted to add, not long ago I read a PDF file about gastroliths being found in coprolites. The occurrence of such being rare in the documented record, and many, even professionals being unfamiliar with the two in direct association. Gastroliths can be small, depending on the source animal, animals can likewise ingest unintended dirt and rock material while eating. Not saying you have a gastrolithic coprolite, just putting it out there so you can explore some angles... --- Joshua tennesseespride@gmail.com Link to comment Share on other sites More sharing options...
InsectariumPlus Posted January 6, 2016 Author Share Posted January 6, 2016 Sorry it took me so long to write back. Busy holiday season and days! Well... the location where it was found is next to some hills made of magmatic/igneous (??) rocks so this backs up all your guesses! Link to comment Share on other sites More sharing options...
