Hello! My friend found a rock on a beach near Ancona, in central Italy, and now he's convinced it's a meteorite. I have some doubts, however: it looks too cracky and porous. I'm attaching a few pictures of the rock: could someone give me an opinion?
Thank you very much for the kind attention,
Stefania
hi you Stefania
OK first up, I don't see any evidence of any of them being a meteorite
OK let's look at each in turn :)
1) this one looks very volcanic in origin ... vesicles ( gas bubble holes) are a dead giveaway that it isn't a meteorite
2) tho this appears to have objects that are similar to chondrules - I would like to see a closer look
I suspect they may be crystal vugs and again the sample appears to have vesicles
3) No, definitely not. This sample appears to be full of quartz or other white minerals
you would never see a meteorite looking so white like that
4) I have no idea of the scale of this image, tho it appears to be well magnified
It also doe
snt have the looks of a meteorite

The owner of the rock intends to get it certified as a metheorite, so he'll seek a professional.
I can pretty much guarantee that they won't get certification
Any professional or semi pro in meteorites like myself would dismiss them immediately
Ohhh and certification costs reasonable amounts of money :)
Personally, I wouldn't want to waste the time of a lab to look at them.
Not a lot of point taking them to an average geologist either, most of them wouldn't know what a meteorite looks like ;)
I have been collecting and studying them for ~ 30 years, have over 270 meteorites in my collection from all over the world
and of all sorts of different types
here's one of my threads on meteorites ...
