Discussion Overview

The discussion revolves around the identification of rocks that a user suspects may be meteorites. Participants explore various characteristics of the rocks, including their shape, composition, and location of discovery, while considering the possibility of them being terrestrial rather than extraterrestrial in origin.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant suggests that the rocks are likely not meteorites due to their rounded shape, which is more typical of Earth-based erosion.
  • Another participant mentions that the rocks resemble a sedimentary breccia and questions their magnetic properties as a potential indicator.
  • There are suggestions for better photographic evidence, including clearer images and the inclusion of a ruler for scale.
  • One participant proposes that the rocks may be iron sulphide (pyrite) nodules based on their appearance.
  • Another participant humorously identifies one of the rocks as a "peppercorn," suggesting it is probably terrestrial.
  • Participants express uncertainty about the identification and request more information about the location where the rocks were found.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether the rocks are meteorites or terrestrial. Multiple competing views remain, with some arguing for terrestrial origins and others suggesting possible meteorite characteristics.

Contextual Notes

Participants note limitations in the identification process due to unclear photographs and the need for more detailed information about the rocks' physical properties and the specific location of discovery.

Hello,
I just found about 7 rocks seems as an oval, when I was drilling, I found a big simple rock and when I broke it I foud them, I wondered,
and I just gussing that's a meteorites, Here is 2 photos of them, I will be very thankful to help me identify them,
Thanks in advaced,

Earth sciences news on Phys.org
Have a look at the Meteorite Identification page from Portland State University and a similar page from UNM.

Meteorites are typically not round. The rocks in both pictures look very rounded, which is more typical of Earth-based erosion. The fact that several appeared in the same rock makes it sound like a sedimentary deposit of some sort.

Thanks Vagn, your answer was very helpful especially in this character, It's not oddly shaped, it's rounded,

not likely, not like any of the 100's of meteorites I have seen, including the ones I own

Here's a small sample of the meteorites and tektites I have

Look more like a sedimentary breccia

Try a better photo ... the focus has locked on the background and not on the rock
and because of that, I cannot tell if it is crystals I can see ( particularly on the second pic) or something else

Is it strongly magnetic ?, that's a reasonable indicator but keep in mind many common Earth rocks
also have magnetic properties, eg basalt lavaDave

Thanks dave,
I have a cleared video about it on my computer, but I didn't find the option how to upload it her to see it, or I must to upload it on youtube then insert the link ?

Maybe just take a couple clear screenshots from the video and attach those here?

yes, you could do that .. a link to a youtube video is a good way
Or as berkeman said ...

Still photos are still the best quality. Whichever way you go, just make sure you have
got the focus right :smile:cheers
Dave
 
And include a ruler in the photo. Oh, and if you have a scale you can put it on to show the weight all in one photo, that too would be useful information.

Hello friends,
This the video that I told you about,
Is this is a meteorite ?

OK, not the best light, too many shadows

As I asked earlier, please take a couple of sharp, well lit photos ( preferably outside in natural light but not in direct sunlight)

I still cannot determine this ...

Where did you find this rock, country and close approx location ?Dave

That's a peppercorn.

Probably terrestrial.

This looks quite like an iron sulphide (pyrite) nodule. It seems to be a mass of cubic crystals typical of pyrite. here's a similar nodule I picked up from the Cretaceous chalk area in north Wiltshire, UK.

Thanks davenn, the stones are so far from me right now, I will try to take a cleared photos next few days,
and about the location, I found them in Chlef city in Algeria country, the approx location is about 35 km near to Mediterranean Sea ( North Africa )

Abdellatif,
cool :smile: I do have a couple of meteorite samples from NW Africa area.
There are several known strewn fields in the region ... mainly chondrite variety
rocky with some nickel/iron present. see my page ...

for some of my meteorites ( I must update it one day, many more to add)Dave
