I learned a bit about radiation when I found an old blast furnace site . These are some important factors that a person should be familiar with when rock hounding . Number one. Use caution there is a lot of pretty stuff out there and if it was put there then it was put there for a reason . Anyways I am not familiar with the measuring scale your using but if you could convert it to mil REMs an airline pilot is only allowed to take in one REM a year . That is 1000 mila RMs. And the second thing is strength of the radiation of course is important but equally important is exposure time . For example alpha radiation is the weakest of the three types of radiation , alpha ,Beta, Gamma but is considered one of the most dangerous because unlike Beta and Gamma that once you remove the object from say a room , the radiation leaves with it. But Beta actually throws off a radioactive particle that can be ingested or swallowed and could become lodged in your lungs for a long time and that's where exposure becomes the deadly factor. If you suspect that rock with those pretty green crystals on it might be radio active then keep it put somewhere safe until you find out .
Wonderful connection between Mojave rocks, sea beds, and the discussion about radiation. Stones just like these can be found along the California coast near San Onofre beach. And yes, I'm sharing the location, because these rocks polish beautifully. Thanks for a great video!
They can also be found in and near the Coquille river system near the coastal range in Oregon . particularly around the powers area above and below the town. I'm very happy to have found your channel and can already tell I'm going to become a big fan fast.this was my first time watching and just so happens that it's on one of the pretty rocks I have in my collection.im just a girl who enjoys the outdoors with my dog and finds pretty and Interesting rocks for the fun of it. Will be sharing your channel with my family and friends.
next step is to look in the literature and see if anyone has reported piemontite or manganiferous portions of it. I don't believe that formation has that though
Nice. This is cool. You are sharing your knowledge in a way that (at least so far) is not gate keeping and requiring subscriptions but still gain an audience and seems to be authentic.
This is the fourth or fifth episode I've watched in this series, and am now seriously considering taking a geology class or five. My knowledge base is seriously deficient!
@@brysonalden5414 that's a great area to study geology: tectonically active, all the rock types, lots of interesting history, and great field trips. I'm sure there are great instructors at local community colleges that can get you started
That was a great deep-dive into their rock sample. We are all smarter from it. Thanks! `i don`t think i want a meteorite` oh you would if you knew what dollar value is attached to those suckers.
What strikes me is how angular some of those pieces are...Were they worked or is that natural? It looks natural. Is it basically the crystal shape of quartz? We just bought a geiger counter for our rockhounding, so I'm stoked to see you look at that! (Be sure to label your new addition to your collectiion)
So Piemontite is associated the Epidote, Quartz, etc? The crystals, if you can find them are beautiful. Volcanic rocks? An Piemontite schist is found in NZ.
piemontite (and epidote) only form by metamorphic processes, never by crystallization from a magma (as in volcanic rocks). there could be an obscure/rare igneous occurrence, but I'm not aware of it.
I found an Indian artifact in SW VA, in HEL sedimentary area. The artifact was cut from is fine grain, strong, green rock. It isn't native to any rocks in the area. The artifact is called a Banner Stone. It would be nice to identify the rock source. As this appears to show rocks used as money among the Indian population.
Great stuff, learned a lot and may have some in my collection found near me in Ontario, Canada, Have you been to the Bancroft Gemboree up near me, great rock show.
@@tectonic_city Hi, I am just a rock hound with no formal training mostly taught by my mother who also had no formal training so I do not know what komatites are, I will check that. . I was referring to the piemontite, I remember seeing the pink colour before in some pieces I found quite awhile ago thinking it was feldspar but now I am not sure and will have to try and find the pieces and check further.
That was curious so I tried googling the safe radiation dosages. The annual public dose limit is 1mSv or 1000 microSv per year. If this is 0.4 microSv per hour just wearing the necklace the whole day (24 hours) will expose you to 9.6 microSv. Multiply this by 365 and you get 3542 microSv per year. This is way above the limit dose of 1000, so I'd say this necklace is actually quite radioactive for such a small piece. By the way, I am talking about the general public exposure. The numbers are higher for those who work with radioactive materials, x-ray workers, etc, so this is still likely considered safe but when it comes to radiation the less the better.
Thanks, Very cool to see. I'll need to do Mose test to 'narrow' type mineral \ stone i find. re: mineral Based on colour; Your 'reasoning' why still believing potassium, XRF was 'Not Calibrated'. 26:43 : }
when I say "not calibrated" that means we didn't perform procedures to interpret the quantitative output of the instrument. For example, it may be that 4% calcium shown by the machine is actually 7% in reality. It doesn't mean that the elements are incorrect. The element signatures are defined by fundamental laws of quantum chemistry that are true everywhere in the universe, so if we see potassium in the XRF that means it is there, although the concentration has a large error bar.
@@tectonic_city Thanks, really just trying to help you 'feel better'. Never expected element to Not be noted if there. Good to know 'Checks & Balances' are available. I've found just trying to ID type rock has turned into Chemistry class, i may get lost, but not stopped.
I am studying environmental science and we do a lot of geology one of my professors is a geologist, but I am still silly and can’t tell my rocks sometimes

Its either wood or FLESH, not more than 2500 years old, in my opinion! Flood of the Bible, less than 600BC. 586, or something aound there. And, California used to be an Island, so it could have been in water before it was turned to stone.
What if I told you I found gold in Kansas State and I know what you're going to say no geologists has ever proven that there is gold there but I've even taken it to two separate jewelers one in Nebraska and one in Lawrence Kansas and they both said yes it is gold and I know that gold can look like fool's Gold and some of its foals called but what I think it is is gold trapped inside fool's Gold what do you think
@tectonic_city and I know what you're talking about It was most geologists always tried to find gold in Kansas and they said that there is no deposits of gold there but mine came from a quarry and it dumped it in a road and I found it in the gravel of the road and based on my tiny little bit of experience and knowledge of geology or rocks some people are saying that it might be telluride gold but I believe it's pyrite with gold trapped inside but it's a hydrothermal rock and I've got pictures on my RUclips channel or videos if you like to see

I have not been on the edge of my seat like I was when you moved to the scope. Please make more videos!!!!
Loving this series it’s so fun getting real people in front of real scientific instruments. I would love to do something like this
Love this!!! Keep making more videos please!!!
More to come!
Informative, fun and yes even riveting. Please keep 'em coming.
Very cool. I'm happy to see the video you guys did a very good job
thanks for coming on Kareem!

@RoysFineGems
You must be a democrat.
💯
love the discuss that a non geologist brings to the table! really fun
Love the channel, glad to have it in my recommended videos. Only a matter of time till you hit the algorithm lottery!
Thanks!
This was my favorite episode from your channel. Very informative. Loved it!
Thanks! I'm glad you enjoyed it!
Very conversational, i appreciate your enjoyment in discovering the puzzle.
Thanks for watching!
🤩 wow that is the channel I did not know I needed ! Amazing! I will binge your content!
Thanks!
Wow, this was funny and really information. You've won a sub in myself.
Thanks for subscribing!

Using Microstrat, I get the Pinto Gneiss 1500-1600ma for the San Bernardino Mountains. Really enjoyed this video.
next step is to look in the literature and see if anyone has reported piemontite or manganiferous portions of it. I don't believe that formation has that though
@tectonic_city that formation says its has feldspar. You could get some tock and do an Analysis
Good episode.
I've been finding similar rocks in western Colorado / eastern Utah.
Ha! NEW to your Channel>45 years or so ago I largely got through Geology 101 by memorizing the specimen collection!
whatever it takes to pass LOL
Cool show, I will go watch more episodes after I subscribe! Thank you
thanks, glad you enjoyed it!
Nice. This is cool. You are sharing your knowledge in a way that (at least so far) is not gate keeping and requiring subscriptions but still gain an audience and seems to be authentic.
happy to share, technically professors are public servants after all
Impressive and interesting. Thank you.
You’re the channel I didn’t know I needed!
thanks and tell a friend:)
This is the fourth or fifth episode I've watched in this series, and am now seriously considering taking a geology class or five. My knowledge base is seriously deficient!
where are you located?
The Greater Seattle area. Thanks in advance for any guidance on programs!
@@brysonalden5414 that's a great area to study geology: tectonically active, all the rock types, lots of interesting history, and great field trips. I'm sure there are great instructors at local community colleges that can get you started
You read my mind! I have been looking at local community colleges. Side note, a friend is coming over Monday to show me a meteorite he found. Sigh.
This was a really good episode.
That's radioactive dinosaur bone is crazy.
Just subscribed. I just found your video but I just looked at the clock it's 3:40 am New Years day will finish watching after I get some sleep.
Happy New Year!
Great video! Just subscribed.
thanks!

@@leechild4655 I have a friend who sells meteorites
Great video man. Thanks for sharing. I would love to see if my dino bone display pieces are radioactive. Thats a trip i had no idea. Thanks man🤙
safe to assume it is until you get it tested
Brilliant. Subscribed.
thanks and tell a friend :)

We just bought a geiger counter for our rockhounding, so I'm stoked to see you look at that! (Be sure to label your new addition to your collectiion)
some of the pieces are cut into cabochons. the others have flat surfaces that formed naturally during metamorphism
I have a piece of chalcedony that has nearly perfect yellow cubes inside it as inclusions. What are the cubes ?
maybe pyrite, but I'd have to see it in person
Reminds me of the quartzite at the climbing area called The Back of the Lake at Lake Louise, Alberta.
So Piemontite is associated the Epidote, Quartz, etc? The crystals, if you can find them are beautiful. Volcanic rocks? An Piemontite schist is found in NZ.

Great video this is some really interesting stuff, what was the last thing you added that turned the one black?
not sure what you mean, can you give a timestamp?

go to your local geology department or next time you're in Southern California you're welcome to come on the show!
Nice, Gneis 😅 greetings from Germany 🤗
Vielen Dank!
I have found the same in colorado and out here in southern california.
Terrific adventure in time and squeeze Mg pink

I bet it has lots of komatiites

This looks very similar to the Piedmont uplifting in Alabama.
You didn’t do a streak test!?
well, honestly a streak test would not have been very useful for this particular specimen. streak tests are helpful for certain minerals only

My rock is gravel. Yay, it's not a very fashionable rock unless you're building a driveway.
I can imagine that the SEM and the saying "I was wrong" is a common occurrence.
100%
Full of mica and garnets and quartz also
Thanks, Very cool to see. I'll need to do Mose test to 'narrow' type mineral \ stone i find.

Hey The Professor, look what I brought, now tell me what's my rock, hahaha, great!!
ive been waiting!
That’s great guys
Never tell anyone where you find your rocks crystals or fossils.
Kareem my man what’s up?
The first Rock I had a few the same color layers etc .. I through them back to mother nature. Lots of does in Canada .
Hey Professor, Im not able to bring my rocks in due to geography and health issues. Can I send you photos?
Meteorites are worth quite a bit...
Gneiss is nice.
It resembles kona dolomite
This rock is a nice, I like!
sorry, somebody had to do it ;-)
Man I got some rocks you can identify. 🤠🦎🤠
you're welcome on the show anytime
@@tectonic_city Thanks. Where are you located? Not sure I can travel to you yet but maybe we could mail you some rocks. Or something. 🤠
