Has Anyone Seen A Rock Like This One Before?


Recommended Posts

I found this rock years ago and had to hold on to it until I knew more about it. At first sight, I thought this rock was a turtle shell stuck in dried mud. Has crystallized breads on it and they can't be scratched with a utility knife. Vary heavy, the size of a vollyball. Not magnetic. Just wondering if anyone has seen or knows of rocks like this one?

Looks like it has a lot of quartz in it, so I would guess that is what it is.

You might want to check it for some gold inside it.

But what do I know as I am new to this also.

Looks like Volcanic Tuff to me. Take a look at the table below and the YouTube clip. This is the best overview of igneous rocks out there.

definitely an eroded light colored intrusive igneous rock with lots of quartz and feldspar and with phaneritic texture from the chart above. Since the green material is only visible on the half that was exposed, the green stuff could be organic or it could be feldspar weathering to epidote. If the green material covered the entire rock it could be original epidote or peridotite/peridot/olivine.

I vote on the green being algal growth.

Thank you all for your thoughts and interst.

I agree that the green is organic. This rock was not green when I first found it. It has been sitting in a garden for the last 10 years. Crystals facing down. 

I am a novist rock hunter as I always look at rocks in my daily adventures. On this day years ago I was on my way to pick raspberries when...

I found this rock in a wooded edge of property.  just off the trail, I see a small roundered area with no vegetation growing in it, about a 4ft. around area diveted in words. It looked like a rock was dropped from the sky.  Right there in the center was what looked like a old turtle shell mostly buried in the mud. So I dug it up to investigate it more. it was this rock.

So far my research leads me to belive that this rock ether could be a local earth stone or it could be a rare stony meterite. Both seam to be possible with my nawlage. The crystals look like melt points to me.

so I am working on a density test as soon as I go figure out how lol. 1.5 times heaver if from space Then if from earth.  If so then I think I'll have to send away for lab testing.  

So what do you all think? Am I just waisting my time with this rock or do you think its possible to be a rare space rock.

Not a space rock for sure, but it is quite beautiful

Should you have a metal detector I would run it over it to see if it has metal in it.

Then I would break it in half to show what is inside.

Not a pallasite or any kind of meteorite, but a cool rock none the less.

Guys, just thought to share these excellent brief rock tutorials.

      Now this is a somewhat subjective category but maybe we can make our own and add others.  What do you think is a famous meteorite?
      I would say Meteor Crater in Arizona.  The meteorites in question are actually called Canyon Diablos.  
      Here is a list from LiveScience and it doesn't include Canyon Diablos.

      There are thousands of meteorites discovered all over the world.  Some areas preserve meteorites better than others.  The oceans for instance degrade most of them and other climates make it nearly impossible to find them.  When they are found they are studied and classified.
      This meteorite was:
      A lonely meteorite that landed in the Sahara Desert in 2020 is older than Earth. The primeval space rock is about 4.6 billion years old, and is the oldest known example of magma from space.
      This meteorite is an achondrite, a type of meteorite that comes from a parent body with a distinct crust and core, and lacks round mineral grains called chondrules, according to the Center for Meteorite Studies at Arizona State University.

      Christie's had an auction for meteorites.  I read the results and the prices obtained were WAY over the estimates.
      You can also use these pictures as good meteorite ID photos in case you are wondering 'Do I have a meteorite.'

      If you saw a meteor fall from the sky how would you find the meteorite?  
      There are many cameras looking at the sky.  A calculation can be made and give an estimate where the strike would happen.  This would be the beginning of the trail and then eye witnesses would assist.  This is what happened with this iron meteorite in Sweden.
