Hi List:
I have a question regarding the metal distribution in ordinary chondrites. I
remember hearing somewhere that in H-chondrites the free-metal is generally
evenly distributed in medium sized blobs throughout the meteorite, and in
L-chondrites the metal is more uneven, sometimes there will be large metal
blobs in one area within the meteorite and elsewhere there is much less or no
metal. For LL-chondrites, Im not sure; perhaps just less free-metal and total
iron throughout the meteorite.
The reason Im asking is that I cut a small (~50 gram) chondrite I got in
Tucson and the metal is very fined grained and distributed very evenly
throughout the meteorite, and there is a lot; it looks different then all the
others I have cut. In fact, this particular piece has more magnetic pull than
any other meteorite (chondrite) I have. Im wondering if it could be an
E-chondrite, because it has so much free-iron and the metal flakes get very
small and vary in size. But this made me wonder:
Is there a way to somewhat estimate whether a meteorite is an H, L, or LL
chondrite by observing the metal distribution inside? Or are there patterns
that fit each class in terms of metal distribution?
Much Thanks,
Greg S
