Need Help With Possible Meteorite ID

Recommended Posts

I guess I'm as big a moron as all the other meteorite wannabees, but here it is. I found this hunk of metal out in the Idaho desert. It was in the vicinity of an old railroad stop.

That railroad dates back to the late 1800's, and that stop was abandoned long ago. I figured the rock had something to do with the railroad, but looking at it the other day, I started wondering. I had it checked at a local scrapyard a couple of years ago, and the gun showed it had +/- 10% nickel. It will cause a round magnet to roll around. It's about 2" across at the widest point. What say you

experts? Everything I know about meteorites could be written on the back of a postage stamp, with room left over. The closeup pic is a small broken face. We ground a flat spot on one side so the xrf gun could get a reading.

Don't be put off by the 'commentary'.  This seems like a pretty good DiY meteorite identifier site.  A ton of info including lots of photos.

Most likely ballast, slag or some type of basalt....the holes tend toward terrestrial rather than extra-terrestrial ....

their is all kinds of rocks around rr stops and along the tracks.

It's not actually rock, Fred.....it's solid metal, though I am definitely not arguing that it's a meteorite....I have no idea what it is.

Yeah...I hadn't even thought of that, but the wife mentioned it while looking at it last night. So, I naturally thought.."I know just where to ask"...LOL. I first thought it was from the firebox of a locomotive, but there's no way that would be hot enough to melt iron or steel. It was found about 100 yards from the tracks. There is quite a bit of junk laying around that area. I think that stop was sort of a track maintenance place. There are cinders along the track there for a ways. There's no water available there. That track originally ran up to the town of Mackay where there was a substantial copper mine, and also serviced the gold and silver mines in Montana, and the Idaho area around Salmon. Now it runs out to the Idaho Engineering Laboratory.

Ya know, that's something I hadn't even considered. I appreciate that idea. It sorta looks like it was formed in rock. I guess I should do a specific gravity test on it to start with. Right now, though, all my time is spoken for. But, that's something I should do this winter.

It's also too big to weigh on my little Gem Pro 250 scale, too.

      After reading reports of the abilities of the Equinox 600 in multi against the 800 I was wondering if anyone has used the 600 for hunting small nuggets as I’m looking at a new general purpose detector that I can loan to friends on occasional prospecting trips , although I’m figuring a 6 inch coil would probably be required also .
      regards PM🇦🇺

      Been out for a few hunts with my Nox 600, mostly 50-100 year old trashy parks.  Everything is just great even got into some river hunts with some success.
       Where I’m having trouble is when I go out to my old coal mining ghost town sites which has trash from every decade.  Also all the buildings have been removed or bulldozed so lots of nails, bullets and flat iron etc mixed around.(Pacific Northwest Washington)
      #1 I’m guilty of mode hopping at the mining site.  
      #2 the site is so trashy I cannot find a spot to proper ground balance!!!!
       
      general settings 
      sensitivity=18-20
      iron bias=1-2 back and forth
      recovery=2-3 back and forth
       
      I would love all tips links etc.
       
      thanks so much for reading

      EDITED.........For a first timer just doing some experimental nugget hunting would it be worth a GPAA membership for access to the claims or just doing some research and hunting BLM land?  Will be in Phoenix visiting a friend after a work trip that ends in Vegas. I am entertaining renting a car instead of flying and trying my luck for nuggets along the way!  
      Thanks...Noah
       
       
      What group/club is best for AZ or NV gold detecting claims???   First time detector prospector looking for a nugget!!!

      has any one air test the scuba tector on large objects ????? i like to know it max range ......i seen its worthless on very small targets ....whats it range on a helmet , rifle ,  truck size object ....the targets i look for  are 12 to 24 inches deep could the scuba tector in wet sand go this deep ???  or does it max out at 12" am guessing 2.5x the coil size like other pi detectors do ....

      any info or ideas  on what would find more nuggets ?????
    • By Swifty
      Seeing that most of the regular posters are experienced detector users, I'm a little curious what type of threshold  you prefer.
      I've noticed there seems to be 3 main choices for threshold.
      1. Running hot, detector sounds a little unstable but still a target stands out from the rest of the sounds.
      2. Running smooth and steady listening for any change in sound at all.
      3. Running close to, or actually silent with a target the only sound made excepting an occasional EMI burst.
      And second are you using headphones?
      I run my 7000 close to silent, and my discrimination detectors with a smooth threshold.
      I use headphones on everything.
