| Why this rock is probably not a meteorite:
1) No fusion crust.
2) Wrong color. Meteorites aren't this reddish.
3) When one drops hydrochloric acid on the rock, the drop "fizzes"
- it releases carbon dioxide gas from the rock. No meteorite fizzes
when exposed to acid. Meteorites don't fizz.
|What is it?
Like number 02, this is a terrestrial o÷litic
limestone. Up close (bottom), there are many spherules. The finder
though that this might be a chondritic meteorite and that the spherules
were chondrules. However, the "acid test" shows this rock
to consist of calcite. That means that the spherules are o÷liths -
calcium carbonate growths on sand grains or organic matter, not chondrules,
which consist mainly of silicate minerals.
