Hello all- I put the word rocks in quotes because we identified what material they are, just not how they were formed and why they were found where they were.
Posting this for my MD buddy. He was checking his yard for clad and whatnot and found 3 of these 'rocks' that triggered his MD. Rocks were found in different corners of his good size yard, not all bunched together.
He brought them to me and sure enough they rang 36 on my Xterra. After tossing different ideas back and forth he went over to my bandsaw and cut one in half- it is clearly an aluminum nugget, or drop, whatever the proper name is.
So, what, where, when, and why? A little background- His home was built in 1974, central Florida. Doubtful that any home was there before his housing track was built. Don't laugh but we even wondered if it 'dropped out of the sky' as NASA is close, and also flight path to Orlando Int Airport is overhead- but as he is probably 15-20 miles north the planes are still very high in the sky. He glassbeaded one of them and it is obvious that they have been in the ground awhile as corrosion pitting is taking place.
These little nuggets appear that a large drop of molten aluminum solidified somehow, but can't think of how it would happen naturally. Also no other signs of 'metal crafting' going on previously in the yard. A third nugget not pictured appears to have a tiny 'spigot' if you will on the top.
Any ideas?
