Here are two
views of a stone of the Mifflin (L5 chondrite) meteorite that
landed in southwestern Wisconsin on April 15, 2010. This meteorite
also shattered in the atmosphere, so the stone is rather blocky
shaped but it still has a fusion crust and the edges are rounded.
Where the fusion crust is chipped away, the interior is light-colored.
This is common in freshly fallen chondritic meteorites. Photo

These two photos
were sent to me by people asking whether the rocks are meteorites.
I'm 100% sure "yes" for the one on the left (the
fellow didn't tell me where he got it ) and 99% sure for the
one on the right (from Morocco). Both have cracked fusion
crusts, some missing fusion crust, and regmaglypts. Click

|Two views of
Northwest Africa 7496 (polymict eucrite). This meteorite is
very fresh; the fusion crust is still shiny. On the left,
clasts are evident as protrusions. (I think this is a bit
unusual.) Click on image for enlargement. Again, the interior
is lighter colored than the fusion crust. Click on image for

views of an unnamed meteorite (probably ordinary chondrite)
from the Sahara Desert. Note cracks and missing portions in
the fusion crust.
This is a beautiful photo
of a cracked fusion crust and many small regmaglypts on an
unnamed meteorite (probably an ordinary chondrite) found in
the Sahara Desert. Thanks to Habib for the photo.
is a rare monomict eucrite that fell in Australia in 1960. This is one
of many stones. The fresh fusion crust on Millbillillie is redder than
that seen on unweathered ordinary chondrite. Photo by Randy Korotev.
Thanks to Karl Aston for showing us the stone.
