[meteorite-list] Strange structure in L chondrite

[Razvan Andrei]

Hello

It might a Fe2SiO4 melt pocket not so unusual in shocked chondrites
Umbarger L6 and Gao H5 also present this kind of structures at the
meeting regions of shock veins. I have also a unclassified, unnamed
Rissani meteorite with this kind of inclusion.

Regards,
Andrei

of the meteorite by the shock veins but I'm not sure.
