I really like the Idea of people getting to bring their rocks in and learning about them while having them identified. I sure wish there were more places and people doing what you do. Thank you for all you do and I look forward to more videos.
This is my favorite episode so far!! It was just loads of fun. Never imagined someone would bring you a maybe old bone or that petrified wood - but they are rocks I guess. What exciting unexpected thing would they bring in next???
You're right, it's petrified wood. The reason for the ovoid cross section is that it's from a root that grew horizontally at the surface of the ground. You often see the tops of such roots at the base of big trees. They may look like they'd be cylindrical, because it's only the part with the large radius that shows. The pointy part is under ground. I found this out because I had to dig out some large tree stumps. Yours is bigger than ones from a 60 foot pecan tree, so I'd guesstimate it's from a tree 80 - 100 feet tall. I'd also guess that the reason for the shape is that it's easier for the growing root to expand up into the air than to displace soil. -- J.S.
Petrified wood is the most logical. Mojave locations it may have been found in would be: Calico Mountains, Boron, Caddy Mountains. I've collected many petrified wood specimens from all of those areas.
I really enjoy the show!! I am a rock nerd who used to bring hundreds of rocks to a geology professor for identification. I am aware I was annoying, however he was patient and provided me with tons of education. He discovered a sapphire deposit that he staked a claim on in the San Gabriel mountains. My Aunt wrote a book on the geomorphic study of California. Geology is in the family, a fun hobby and a passion. I am glad you are doing the same for many more people. If they are willing to learn you are definitely providing them lessons. I spent several years exploring the Mojave desert. I've always had a great time finding the vast secrets the desert holds. Again I appreciate your show.
It takes a confident person in any field to be able to tell someone their honest opinion even if it is not what the person asking wants to hear. That's the hardest part of identifying a mineral. Quartz comprises of a huge family of relatives that can take many different forms and appearance. Man made byproduct is everywhere which people assume are naturally made.
Just found this- what a great idea! So nice to hear someone go in-depth on "just" a rock. So often no on has anything to say unless it's rare or showy. Starting at #1 and going to work my way through all of them to catch up!
Being able to identify a rock is easier in hand versus pics or videos, but I believe the second specimen is an actual rock. I have quite a few that have that bubbly frothy appearance that I’ve considered to be chalcedony and/or chert, here in Texas southern plains. Majority of my finds are in gravels or decorative yard gravels. Just sharing my amateur thoughts.
I bet it’s the bark texture of a root base that’s been cast in (edit: looks agatized or cherty). Their insides are usually solid no rings like the trunk
Close, it's probably a limb cast. Basically, the wood itself rotted out of the rock before the silica came along and filled the cavity, so the internal structure of the wood is not preserved.
Couldn't silicate rich water and or mud flow through and or possibly be trapped inside a preexisting formation and over time mineralization occurs creating( in this case ) a chert like material ? And when the host formation broke apart, this specimen could have been freed from the cavity it formed in, kind of like a casting? @@tectonic_city

Second sample : Industrial blast furnace slag,
Mining slag_ refinery slag glass?
I like that there are so many opinions. I don't feel too bad for confusion.
I would definitely slab and polish the "petrified wood" you would definitely be able to confirm it then. Loving the channel 😊

Really enjoyed getting to see how you approached these rocks!
Glad you enjoyed it!

I enjoyed this so much! Dry cool video and I hope to see more!
thanks
10/10 incredible job and incredible people
First one did look like chert. Second one could have been part of a spacecraft.
23:18 it’s not mining slag?
I'm your 18th subscriber here. Please upload more about gems and rocks.❤
more to come...
@@tectonic_city 👍
I'd love to get my hands on one of those XRF's, I'm not sure there are any out there us mortals can even dream to afford.
only $50,000 lol
@@tectonic_city Exactly :-)
So what if it's not petrified wood, but the substance that filled a hollow log and that's what took on the bark like texture? 21:58
that's basically what petrified wood is: silica replacement of dead wood
Close, it's probably a limb cast. Basically, the wood itself rotted out of the rock before the silica came along and filled the cavity, so the internal structure of the wood is not preserved.
Hi sir! I have some rocks they are attached magnet. Can you help me to identify this thank you very much
Sorry I don't identify rocks by pictures
I live in California. I can bring my rocks to see you thank you very much sir
@@tectonic_city I can bring my rocks to see you thank you very much sir
The chipping faces on the first sample look a LOT like slickenside as well :)
I can see the resemblance but slickensides aren’t usually present on a quasicylindrical orientation like this one
Where can I pay that machine you got and the name please
I'm a new rock hound down in the Coachella valley, and would love to be a guest on your channel .
Send us an email at whatsmyrock@yahoo.com
that things definitely ventilated (wind blown).
How much that X-ray and the name of it please
$50,000
I agree with pet wood.
Someone abandoned their pet on the side of the road?!
22:10 superstition or a spiritual belief about not taking PW from its origin location?
That very well could be a fossilized wood.but posibley a lava or mud tube
but the composition is mostly SiO2. for lava or mud, would need significant Al, K and/or Ca, more Fe, etc.

Seriously, refried beans?😮
Mayroon akong parehas anak sir tawag circle
Dang, let’s cut them. 👀 😬Is it possibly agatised pet wood?
Wood!
Paleontologist evaluation?
Pet dino poop
Commercials are too long. Can't waste that kind of time to watch your videos. TOO Bad
Looks and sounds like petrified wood.TY
