I am so very pleased to announce a very important find at Ryerson Hill Quarry. This find is significant.

Brookite was found in the study area this month and confirmed by xrd analysis at the Maine Gem and Mineral Museum by Alexander U. Falster.

This completes the triumvirate of possible TiO2 minerals.... Brookite, Anatase, Rutile. This is the 1st occurrence in Oxford pegmatite and the Northeast. Plus only the 3rd occurrence in the United States and 5th or 6th in the World.

There is a lot more to come from this find as it helps clarify even more what happened at Ryerson. Alexander U. Falster, Dr. Skip Simmons, and I will be working to produce a manuscript or article for journal or other publication. There is no date or timeline for that as it will be a complex process.

I want to say that this find takes so much weight off of my shoulders and truly makes me proud. Despite the shenanigans of "planted brookite" the studying went on and the process continued to be done right. That resulted in stress and took away a lot of fun of studying. However, science won and in the end hard work with dedication proved to be what was needed.

This "Ryerson" brookite was found in situ and there is more than one piece as well. The scan is very clean and the elemental composition matches the minerals in and around the Molly Pocket.

This is a truly exciting find of brookite, anatase, and rutile. Largest anatase crystal in Northeast and comparable to all of North Americas anatase crystal finds. The three TiO2 now add importance to understanding and science with the rarity of the occurrence.

I am proud, excited, thankful, relieved, and very much looking forward to the journey ahead on this project.

Here are a few images of material from the Molly Pocket from 6-1-22 that were shared in the presentation. I would love to share the presentation here but no way to share a powerpoint here.

I would love to share more but until I know what is going to be used for publication, this is all I can share.

Enjoy....

Yesterday the Ryerson Hill presentation at the Rochester Mineral Symposium was a great success. It was very well received around the world.

Many kudos on the study and the integrity of it. The integrity of Ryerson doing it right, right from the start.

A few comments…
“
Phenomenal presentation at Rochester. The stuff legends are built on.
Anatase:stellar.
Brookite: unforgettable!
Delivery: Impeccable.”

“It was excellent. ——— called and told me how impressed he was with your talk”

Here is a picture of Al and I with the Big Three Anatase. Felt great to finally share this amazing find.

Did you miss the presentation? Well, you can see at the NEMA conference in May at Sunday River, right here in Maine.

I added a new mineral from my study. Todorokite to put Ryerson at 101.

50th Rochester Mineralogical Symposium
Time to Register for RMS 2023!
Join us April 21-23, 2023
* Please share this email with friends and family *
Hello RMS Family!
We are delighted to invite you to the 50th Rochester Mineralogical Symposium, the eRMS 2023. The 50th RMS will be online with the same format as last year, Friday evening April 21, Saturday April 22 and Sunday April 23. We have great speakers – the full program is below.
The 50th RMS will be the final Rochester Mineralogical Symposium, and we hope you will all join us!
Our January poll to all of you regarding the cost of attending an in-person RMS resulted in a very high response rate – we had more responses than we had attendees at our last in-person RMS, with almost all regular in-person attendees responding. The final vote result was an overwhelming number against and few in favor.
Our decision about the future has not been easy. It’s not where we started and it's obviously not what we hoped for. We completely understand the poll responses – dividing the real cost over our people means each of us would have to pay a lot to make it happen again. Our economic deal with the Radisson was so good and so far out of step with what a contemporary event of this kind costs. Of course other issues have also been considered too, but the loss of the Radisson is the one that has undone us.
As you'll expect, this decision has involved many discussions. We've talked about alternatives. We will elaborate a little at the RMS, but in summary, many of our RMS family feel the potential alternatives are not at all as inspiring as the real, in-person RMS. Any event that could follow would not be the same kind of event as the one we've all loved over the years – it would be much diminished.
The RMS was founded specifically as an event intended to bring together enthusiastic collectors, curators, professionals and dealers – to meet, to interact, to share – in the Thursday-Sunday format that was initiated at RMS 2 in 1974 and continued annually through RMS 46 in 2019. We won’t be able to do that again. That is what was most special to many of the people who have made the RMS all that it is and has been in Rochester: a full cross-section of mineral world people gathering over minerals and socially, meeting and getting to know each other as new mineral friends, and then reconnecting annually as good friends.
We’ve done our best to keep the spirit of the RMS alive and well online and thanks to all of you, this has been an excellent chapter in the history of the RMS.
We know you will be disappointed we’ve reached the end of the RMS. We are too. We'll do our best to deliver a great last one – we look forward to you being a part of it!
