erose Posted September 24, 2018 Share Posted September 24, 2018 pretty sure it is mineral, not fossil. Link to comment Share on other sites More sharing options...

KimTexan Posted September 25, 2018 Share Posted September 25, 2018 If you found it down here I’d say it may be a fragment of very eroded Inoceramus clam shell, but I doubt those are found in your area. I agree it looks like a mineral that is kind of worn down. Link to comment Share on other sites More sharing options...

We find lots of calcite chunks that maybat times look a bit like this when exposed for long periods of time. You can find little faults in North Texas over maybe 0.5 to 1.5 inches filled with slabs of calcite. Link to comment Share on other sites More sharing options...

I used to collect this type of material thinking "fossil" until I was on a group hunt in a quarry and someone explained a very long exposure of sylolite to me.

DPS Ammonite Posted September 25, 2018 Share Posted September 25, 2018 This is not a styolite but rather a vein of a striated mineral that may be calcite. A hardness and acid test is needed. Does it fizz in vinegar? Will a steel knife blade scratch it? It is not a styolite because the striated structure appears to encircle the rock. Styolites are irregular, but on average, follow a plane. Styolites are usually dark, serrated boundries in limestone where the rock has dissolved, through pressure solution, leaving behind insoluable residues such as clay.

Innocentx Posted September 25, 2018 Share Posted September 25, 2018 I find these around here(Virgilian) in limestone and they are vertically oriented and often circular. They appear to be of the same material as the surrounding rock and I thought they might have some things in common with cone-in-cone structures.

keldeo072 Posted September 25, 2018 Author Share Posted September 25, 2018 It did react to vinegar and was scratched by a copper penny so it must be calcite then. 2 Link to comment Share on other sites More sharing options...
Herb Posted September 26, 2018 Share Posted September 26, 2018 It is a styolite.They are very common in the Silurian dolomite (dolstone) in Ohio and KY . The Fairborn area has mostly Ordovician but there is also a little Silurian nearby. They are often blackish but not always and there are lots of variations. I can get 100 lbs of them within 10 minutes of my house. The dolomite one will also fizz slightly with acid. 22 hours ago, DPS Ammonite said: This is not a styolite but rather a vein of a striated mineral that may be calcite.

These look different than the styolites that I have seen up til now. I searched and found some that go in many different directions and encircle pieces of rock on all sides. On the striated pieces in the third and fourth photos, are we looking normal to the plane of the styolite? On the first and fifth photos, are we looking parallel to the plane of the styolites?

supertramp Posted September 26, 2018 Share Posted September 26, 2018 john, I think that in the first and fifth photos, we are looking parallel to the stylolitic plane, with the columns raised by erosion so that you do not see the blackish insoluble residue; picture from https://hiveminer.com/Tags/stylolite/Recent Link to comment Share on other sites More sharing options...
Innocentx Posted September 27, 2018 Share Posted September 27, 2018 I went out today to find lower Permian version of Stylolite. There were no good overhead shots but I did find these vertically oriented ones (if that's what we've decided these are). 1 "Journey through a universe ablaze with changes" Phil Ochs Link to comment Share on other sites More sharing options...
