Here's the story of how I found this mysterious rock today.
I was playing catch with my brother on the side of our house, he threw a wild pitch and it hit back up on top of our retaining wall, which is approx. 4ft high. I jump up the wall and after I jumped back down, this rock caught my eye. It couldn't have been there long, because we play catch there at least twice a week. It was near the edge of the retaining wall, on top of the mulch we have there. It must have rolled down because the ball hit it or something..
Anyways.. Here are the tests I tried to determine if it is in fact a Meteorite.
- It is slightly magnetic, but it is definitively magnetic.
- My detector detects it, but only when you swing it a certain way, it reads Iron on my Ace 250.
- It has more density than your average rock of the same size.
- It does have a sort of 'Fusion Crust', which means that it has a thin black rind, sometimes shiny, sometimes matte black, which is acquired during burning in the atmosphere. It does have a shiny black surface in spots and the red/brown all over.
- It has various sizes of dimples, not needle-like holes in it, which would narrow it down to a volcanic rock.
- The red/brown coloring may be the patina that shows up on meteorites that have been on earth for a long time.
- I tried the streak test and I get a very light reddish brown color. I used it on pavement though, hope that still works.
That last one makes me think it's Hematite, but my brother is taking it to the University on Monday to get it tested for free. Oh yea, and it's about the size of half of a baseball.
Let me know what you think!
