Kimberlite or Pudding stone?

I spent a couple of hours today pulling all my landscape rocks up and power washing them all for identification.. After spending the last few days learning all about Kimberlites, I set out on a mission to see if I can identify one. Of course it could be seeing what im looking for, I think I found some kimbwrlite!

    I find myself looking at different rocks and picking them up and polishing them. My family thinks my cheese slid off the cracker so to speak. So I find your video very interesting and good to see someone else infected with the same symptoms i have.
  • My friend I thank you for helping me to realize that I’m not a madman. I went through the same strange obsession over the past couple of years and it led me to a whole new world. I am not a geologist by degree but I agree with other comments that the one looked like a bone of sorts, one looked like it could’ve been jade, and the green stone did look like kimberlite which I too have stumbled upon here in CO. Mostly though the main lesson I’ve taken from my obsession is how many artifacts are out there. Now I don’t know if they are artifacts because some amazing ancient civilization made them or if the Great Spirit created them but they have a story and something tells me you have a calling to help humanity through something big. Trust yourself and follow your heart🤟
  • The 2nd large weirdly shaped rock you showed looks to me a little like a whale vertebra. In Victoria/Vancouver BC I find huge ones in the woods every few years and the ones that I could carry I brought home for my porch.

    Nova escrita excelente trabalho com lindas pedras muito interessante 😮 obrigado por compartilhar 🙏❤️💙💚👍
  • That's awesome, nice to see others that are all in and wanna know what they ( rocks / crystals) ha , keep it up and hope that you found your answers ...and kimberlite can be white too I guess, looking myself, how I found this video , so thank you. I recently did a yard dig, found some really neat stuff too.

    The veins of crystals you see are called dikes. Dikes form when silica-rich motlen rock flows through cracks/fractures in another type of stone, producing veins of crystalline rock. If crystals are very large and visible (phaneritic), this means the liquid magma cooled very slowly because it was deep under the earth where it stayed hot. If you see small crystals, the magma cooled very fast above the earth's surface (aphanetic). The pattern of rock you see if from weathering, where motion and chemical weathering eroded the metamorphic rock much faster than it did the quartz crystals, causing them to stick out. If you live in Michigan, those rocks were probably deposited there about 20-30 thousand years ago as they fell out of the melting glaciers. They look like rock that is typical of the Canadian shield, pushed south by glaciers and glacial flow.

    Moved to NE Michigan recently. Here, you can legally collect up to 25 pounds of rocks per year from state parks. We have two state park rockhounding expeditions planned for this year. One is Sturgeon Point (Harrisville, betw Alpena and Oscoda), which has a mile-long gravel bar jutting out into Lake Huron that's chock full of fossils. The other is Rockport (north of Alpena), which features a mountain of quarry tailings, mostly fossils including Petoskeys, trilobites, and horn corals, many of which are free from their matrices. We'll be staying late to flash for Yooperlites 👍

    There is a textbook from the U of M that tells everything about Mich geology. It is called "Geology of Michigan", by Dorr and Eschman. A used copy isn't that much money. I have studied it for years. I think that you would enjoy the knowledge it brings. Your local library probably has copies available also.
  • Dude that one with the Quartz is full of gold! you can see it easily on the big tv. You commented on how heavy it was!!!
  • I agree that they do look like kimberlites, however to classify a rock as a kimberlite is a lot more difficult than one would think, geologists take several classes devoted just to kimberlites, and without access to proper testing equipment, it is not possible to positvely id a kimberlite... a geologist told me that... and they are still learning a lot about them, 30 years ago no one even thought they existed outside of africa, but like your video thanks
  • That 2nd one looks like granite(or other similar looking intrusive igneous rock) with quartz seams. It is oddly shaped as the crystaline quartz is less prone to weathering than the granite. Highly doubtful that it is a fossil, but weirder things have happened. The first rock you showed looks like it has a quartz seam running thru the middle, the 2nd one has quartzes that have been detached on the "outside" from the host rock The pudding stone is sedimentary not igneous. Look up congomerates and breccias. The individual stones in the matrix might be igneous, but the whole rock is sedimentary. The greenish one nearby looks similar to another type of sedimentary rock that is found out here on the west coast. I don't know enough about kimberlites to speak to that idea, but you live in an area that was covered by glaciers and you probably have all sorts of stones not native to your area. Identifying rocks is difficult generally as each rock is made up of various minerals and you need to identify each mineral in the specimen and where it is from to get an exact definition. You can get kinda close visually, but lab tests are required for definitive id.
  • Sorry. That is a classic jasper quartzite Puddingstone from the Lorrain formation, Huronian Supergroup. Yes, good ones often do contain that many clasts - not formed by lava - sedimentary to metamorphic. Not diamond. Not Kimberlite. The other greenish one, sure could be kimberlite.
  • 8:00 some Canadian Kimberlite does look like that, the tone of the host rock is right. If its been deposited by a glacier from Canada, then you could be right. With the Glacier paths, if you map from your region to where the glaciers came from. You can find placer deposits of gems and mineral. And with canada being such a large source of diamonds. Its not unheard of.
  • Have you not tried a diamond selector to test as they sit? I'd start there. Mohs hardness scale.

    Very interesting. I just got back from Northern Michigan, Gaylord area. I found a bunch of rocks I suspect are kimberlite and also 6 good size "pudding stones" Hmm. I already have some rocks in acid some smashed with a sledge and I have the loose material under the microscope at this very moment. Just an FYI, Diamond has 4 sides and quarts crystal has 6 sides.
  • @tarfeathered791
    The green rock is a good candidate for a kimberlite. The puddingstone is a puddingstone.

    I’ve been reading up on kimberlites and maar - diatremes and I have ran into the same issues identifying what I’m finding. I have found similar rocks to the lighter one you have and I can’t really tell if it’s just a hunk of old concrete or volcanic breccia. I need the fancy equipment that scientists use to run chemical and isotopic analysis! 😂
