On the right is one of many fragments
of an L5 ordinary chondrite from Algeria known as Northwest
Africa 869 (L4–6). On the top, the fusion
crust is still intact. Notice that it is smooth with no holes.
The rougher portion on the bottom of the photo is where the fusion
crust as broken off after it fell. This meteorite probably also
fell thousands of years ago and has been exposed to harsh conditions
in the desert.
Note that there is no obvious metal. L chondrites do not contain as
much metal as H chondrites. The rock is moderately magnetic, however.

Above left and right:
Two views (direct sunlight) of an unclassified ordinary chondrite
fragment from the Sahara desert. The fusion crust is dark and smooth.
If this were a fresh fall, it would be shinier. In most meteorites
the fusion crust is darker than the interior.
On the right is the weathered, broken face of the meteorite (electronic
flash lighting). Rusting of the metal grains has led to reddish staining.
Up close, shiny, unrusted metal grains stick out. Click on image for
