Creek - Don Posted January 31, 2022 Share Posted January 31, 2022 (edited) I've been finding lots of these small black pebbles right above the late Cretaceous gravel layer in the creeks nearby. These are very dark in color and when you strike both rocks together, it smells like sulpher. These rocks also stand out compare to other light limestone rocks in the area. Not sure where they came from or how they ended up here. Most measures around 1 inch or less / 25.4 mm. I also tried magnet test and non-magnetic.

FranzBernhard Posted January 31, 2022 Share Posted January 31, 2022 Don´t look like tektites to me. Too grainy. Not glassy. Seem to be some kind of quartz-based rocks. Franz Bernhard 1 1 2 Link to comment Share on other sites More sharing options...
Lone Hunter Posted January 31, 2022 Share Posted January 31, 2022 Not sure what formation your in but I find those in Eagle Ford, they're weird like they have a coating of something. I've wondered if it had anything to do with oil. Link to comment Share on other sites More sharing options...
Bone Daddy Posted January 31, 2022 Share Posted January 31, 2022 Agree with Franz. These don't look like any tektites or impactites I have seen, and I have seen a ton of them from localities around the world. Having said that, I have no idea what they actually are. 1 Link to comment Share on other sites More sharing options...
Creek - Don Posted January 31, 2022 Author Share Posted January 31, 2022 (edited) Thanks. My another guess is that these stones may been carried over from other areas during the erosion process that occured many millions years ago, probably around Eocene. These are found only between Cretaceous- Paleocene boundry. Have not seen anything above or below it. No oil either. Rock was found above Austin Chalk fm.
