I just tried to attach from a PowerPoint file which seemed to not work. Here is an attempt from another file. Fluorite needles were found several times at Delphos, always in petroleum-filled pockets, and also at Lima, Ohio (same limestone formation). Lima also produced a couple of fist-size pockets of fluorite that had unusual rounded edges. The Delphos quarry now seems to be idle, at least for the time being. The rock layer that produced the fluorites shown rises toward the west end of the quarry (the latest blasting direction) and has been eliminated, but the underlying rocks, now in the upper layers, have produced some nice bicolor fluorites (yellow/purple). Sizes will be estimates for some of the pictures shown. I'm not sure of the status of the Lima quarry.

It's great to see this picture again, John. To give a little quarry history, it had been closed to collecting for many years due to a death (a former worker drove a recreational vehicle off a quarry wall by mistake); Pete Richards wrote a letter and the insurance company (surprise!) let him and me collect. You were in the Columbus, OH club and also went up there with me. We were very lucky to enter at that time since the quarry direction went away from that nice fluorite/sphalerite area after that, producing similar material, but sporadically. Here is another sphalerite inclusion for you and Pete.

Hi John,
Thanks for posting more about Bluffton. I still have some nice micro material available from there. It was a great day collecting with you. It was also nice that some of the Bluffton
pieces had dolomite crystals, sphalerite crystals and fluorite crystals all together.
I'll try to get some pictures up.
Thanks also for posting those incredibly interesting fluorites. I love to see such interesting puzzles.
Cheers,
John

As with Pete Richards, many of my pictures are not digitalized yet, but here are a few examples that I do have. Duff quarry is the closest productive quarry to my home and the unusual amount of rain this past year kept blast areas washed for easier collecting. The quarry produces an unusual number of forms of pyrite, as Pete has mentioned, sometimes also with nice iridescence. A large percentage of the pyrite openings are filled with calcite which must be removed to expose the crystals however, and this process usually removes the iridescence if any was originally present. The Auglaize fluorite iridescence is due to hydrocarbons, as determined by John Rakovan, but I don't think anyone has studied that of the pyrites from Duff quarry. Diploid pyrite form is more common than usual at Duff quarry.

A couple from Ross County, another Ohio pyrite locality. The first shown was not in our Tucson display last year. It was too wet to dig at this locality this past year.

John, I am a lover of your Duff Quarry pyrites although I live very far from Ohio, I am afraid.
I posted a specimen with comments on the Spanish side. There we provided two links you likely know. If not, here you have:
https://vasichkominerals.com/Dufflatest.html
(link normalized by FMF)
and Pete's useful description
https://www.mineral-forum.com/message-board/viewtopic.php?t=1071
From my point of view, you are a lucky man living close to those amazing crystals (well, here in Spain we have Navajun, Ambasaguas or Carratraca as well).
Best regards

Two more images. Both coming from the Spanish FMF Gallery.
The Calcite is from geoalfon and the Sphalerite is from Marc C
