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.

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

Yeah I’m seeing a granite cobble, possibly a pegmatite. Those are some pretty coarse grains, even outside of those larger vuggy zones.

      A bright green meteor streaked across the southern coast of Tasmania, Australia, and researchers caught the fireball on camera as it broke up over the ocean. 
      The meteor lit up the night sky on Wednesday (Nov. 18) at 9:21 p.m. local Tasmanian time (5:21 a.m. EST and 1021 GMT). A livestream camera on the research vessel Investigator, which is operated by Australia’s national science agency, CSIRO, captured incredible views of the fireball as it descended from space and disintegrated above the Tasman Sea.

      Hey everyone...
        Now weather is getting much better, I got a chance to visit a place I havent been to in a while.  Franconia, AZ meteorite strewn field. I met up Saturday morning with a buddy Greg. Greg ended up getting the large complete crusted Chondrite and large iron meteorite on the right, I found the smaller 3 chondrites and irons on the left.... Franconia's always a fun place to visit. A lot of large basalt (hot rocks), .50 cal bullets, .30 cal bullets, wire, ect out there, but after an hour or 2 of adjusting my hearing to the tones, you start to hear the differences between trash and meteorites, ok not 100 % of the time, but Id say over 50% 😉... Dont know about everyone else, but no matter what place I go to new or old, I have to get the good ol hearing adjusted again to the environments, be it gold, meteorites, coins, relics, ect.....
      See ya in the field,
      Dave

      My daily wake up includes a trip to spaceweather.com as well as here and news sites.  Today they had a rather cool article and video or a meteor explosion in China I thought to transcribe here and share 🙂
      Article from Spaceweather.com and link to video from their gallery *they have a lot of cool stuff there* :
      AN EXPLOSION OVER CHINA: Every night, the Chinese Meteor Monitoring Organization (CMMO) runs an automated camera in Shandong Province, monitoring meteor activity above the coast of the Yellow Sea. On Aug. 16th, it caught the brightest fireball in years. The night sky turned blue when a space rock exploded hundreds of times brighter than a full Moon:
      "The meteor illuminated the whole earth and shook the landscape with a loud sound," reports CMMO staff member Zhou Kun. "The flash of light, which peaked at 22:59 pm local time, was widely observed across the Shandong and Jiangsu provinces of China."
      Kun estimates the astronomical magnitude of the flash to be -20, more than 900 times brighter than a full Moon (albeit not as bright as the sun). If so, that would make it a rare fireball indeed. According to a NASA computer model of Earth's meteoroid environment, a fireball of that magnitude could be a decade class event.
      More information about this event (including a possible meteorite debris zone) may become available as the CMMO team analyzes "a large number of eye-witness reports," says Kun. Stay tuned.
