The surface is wrong for meteorites, and meteorites would not have voids like that. Here is an example of an iron meteorite. NWA 850 "Taza" plessitic iron meteorite, oriented.

I found them in a mound of dirt and rock that trucks haul and empty when they dig or blast.

The streak is dark grey and the hardness is between 7 and 9.

I don't know much about meteorites, but this link seems helpful:
www.usgs.gov/faqs/i-think-i-found-meteorite-how-can-i-tell-sure

Some relevant parts from the linked website:

"Bubbles: volcanic rocks or metallic slag on Earth often have bubbles or vesicles in them, but meteorites do not."
"Streak: if you scratch a meteorite on an unglazed ceramic surface, it should not leave a streak. A dense rock that leaves a black or red streak probably contains the iron minerals magnetite or hematite, respectively, neither of which are typically found in meteorites."

Iron meteorites do not leave a streak.

I have been collecting meteorites for a long time and have a very large collection.

rocknrob: That was one heck of a windstorm that thankfully missed me. I guess Seatac almost hit 60mph gusts. I bet those were some fun landings Nov 20, 2024 21:55:16 GMT -5
