Thanks Rich. It's Deb's baby. I think she hasn't yet seen the potential of this stone. I hope to help her see the light!

The only claim I have on that is my claim to be the finder. I want to know what it is, and would love to see it worked, but shotgunner, it is your baby now! Watching with interest. show me the light! (thank you )

After reading through all of this I think it is brecciated pudding jasper with inclusions. But I am just an amateur specializing in rocks of various genders and hounding for anything pretty (females included). Jim

how about this then, look at the second image on the left side of the page and tell me what you think? glacial transport a long way from home? getting closer? www.rockhoundshop.com/rock.talk.htm

What you have there appears to be Dallasite, from British Columbia, Canada. C-ya, Rick

It's definitely similarly formed, but looks a little different. I do know a green rock that shows up in some of snow mom's posts looks just like one I find here.

so maybe the same materials, formed in a similar fashion, but not quite the same. I know we do have all the basic ingredients that are in Dallasite here, and the UP and this area were once highly volcanic. I do find stuff the same color frequently though not the same structures. It will be interesting to look especially for this stuff when rock hunting resumes in the spring. 11 inches of snow here overnight on the eve of Thanksgiving and during that day pretty much puts the stop on my rock hunting for the season.

The pretty ones with cracks fractures are female and the ugly ones are male whether they have cracks fractures or not. Getting beat about the head and shoulders is just another day for me. Jim

Yo, captbob - Chill out, man - Nowhere in this post did it say that this was found in Michigan. I was just tryin' to help out and didn't need you to be slamming me for it, boy... Rick

thank you Gemfeller, I agree, and have been aware that there are 3 kinds of rock in the onaping layers surrounding the impact site. I have had a very difficult time finding clear examples of the green and the gray members, in photo or in my beach searches.( especially the beach searches, since that stuff is not labeled! it is like looking in a crowd for a person you have never met) I am quite sure of the black in my possession due to finding many clear enough photos and descriptions online. I have things that I think may be green or gray Onaping, but have found nobody (yet) who can confirm or deny that this is what they are. I find I have two fairly large pieces of olive green colored material here in my rock pantry which may cut to look very much like this stuff does. The interior is so completely different from the worn exterior! The mystery continues until I can find somebody who really knows their Sudbury material and can confirm or deny. I have made attempts to contact experts, specialists, and collectors in the field , but have received no response (yet). Everybody is busy for the holidays, and the growing interest in meteor related things has all the scientific institutions under tons of stuff waiting for analysis. A little bit of common impactite is not going to get anybody excited. Shotgunner's willingness to accept a piece of this rock as well as some samples of another mystery material I find here, to cut it, post it, and to help do the search for answers is so generous,(thank you) and I deeply appreciate all the input I can get! feeling as though we may be making some progress.

After lunch Saturday with @shotgunner and his lovely family I am in possession of the end-cap - I've glued it to a board and it should be ready to take a whack at it soon. Weather is bad (by CA standards haha) and I work from dark to dark but I should be able to create something to show soon. FYI - I'm not much help with your geological search for information. I did well in college geology but I didn't retain much - I took it as what I thought was an easy class to fill a requirement and it nearly killed me haha. Hopefully I can help you assess the value of the material from a lapidary standpoint. My first impression is to agree with rykk that it reminds me a lot of Dallasite - as BCRH pointed out the breccia pattern is different and the green is not as pronounced in this example but there are distinct similarities.

Tommy - Another good reason to give you a sample! You have had dallasite in your hands. If this is related to dallasite it's more "rock like" and less "dallasite". The epidote is not apparent visually, nor is the pumpellyite. I suppose the main dark green bit could be gemmy basalt.

snowmom - have you read this paper? Did you email avermann? He should see my pics. Rick, if this material is chlorite rich, then it metaphased from the impact. It is agate hard. Actually, agate did not scratch it but quartz did.

shotugunner, no I have not tried to email him. I don't speak or write German, and the paper looks to be from 1994. No references cited are current. I have tried emails from other posts like this in the 1990's and inevitably they are no longer active. I could try one more. There are hundreds of papers citing structure of Sudbury formations and detailing types of materials found since so much mining has gone on there for so long and the search for new ore rich sites is ongoing. Many have poor photos, many have microscope slide analysis, some have core samples and analysis, many have maps of formation locations in good detail. Sudbury impact material is common. not very interesting stuff to many, They grind tons of it every year in mining nickel and other ores. I glean what I can from the reports and other papers regarding the makeup of rock in the areas described. I have concentrated my email queries on Ontario rock and mineral clubs and shops, meteor/impactite collectors, sellers, universities with space studies , and space study institutions, as well as museums and Universities, mostly from Ontario and Michigan quite a few from farther away, but all in the USA. The Smithsonian is "the" place for analysis and ID, but they are 5 years or more in backlog at this point from reports on meteor hunting and collecting sites. Jasper and jasper breccia is listed as being very common in these reports, so that would be in line with your observations.

shotugunner, no I have not tried to email him. I don't speak or write German, Judging by the paper his English is as good as mine. I have found European scientists keep their email addy's longer than their western colleagues.
