Here is a lovely copper with a small calcite crystal and micro datolite crystals from the Quincy Mine, Hancock, Michigan. The copper shows some dodecahedral crystals with edges modified by trapezohedral faces. It is 7.3 x 7 x 5 cm overall, and was originally in the John T. Reeder collection, now in the A. E. Seaman Mineral Museum collection.

These copper crystals have the morphology of laumontite and appear to be pseudomorphs. The crystals are approximately 1 cm tall. Franklin Mine, Hancock, Michigan. Ex John T. Reeder collection now in the A. E. Seaman Mineral Museum.

Sulfurs from this quarry are really fine- probably not getting the attention they deserve. I personally collected small crystals there in the late 1980's. The A. E. Seaman Mineral Museum has a fine collection of sulfur and celestine from
this locality.

Is this truly a pseudomorph (sulfur after celestine)? It sure doesn't look like one judging by the photograph. The morphology is perfectly correct for sulfur and it appears to be a single crystal, not what one sees in pseudomorphs.

Are there other known examples?

Sure, I agree. Here you have one more from there

Hi Antonio, a very nice sulphur specimen. I never heard of that quarry before, but these specimen nearly looks like from one of the famous mines on Sicily, really great!

Hi Tobias,

neither I knew that locality when I got the specimen. Little enchanting surprises of collecting minerals!!

In my case it is usually a bit easier to improve my collection after reading a lot here about minerals all over the world. But regarding this sulphur the specimen came first and then the Forum :-)

Cheers

Still hoping for a response from rweaver to my inquiry about the sulfur pseudomorph after celestine. Perhaps John Jaszczak might weigh in on this.

When I posted my original reply about Michigan sulfurs, I didn't immediately note that the post mentioned pseudomorphs. It also looks like typical sulfur morphology to me; I'm not aware of any pseudomorphs after celestine in our collection (and find it a bit hard to imagine it happening in the deposit). I was waiting for George Robinson to return from his trip out east to confirm with him, and also to get some photos posted of our best sulfur specimens. We'll have to dig through our old photos since the collection is still in storage and I can't shoot new ones for a while. (Carpeting has now been installed in the new museum so I hope to post some new images of the building soon. We hope to start moving in in early May!)
