[meteorite-list] Question Flow lines structures

[cdtucson at cox.net]

List, 
I have a question about flow lines or flow structures. ;
Are they definitive of meteorites.
Please see picture of flow structure of millbillillie eucrite flow lines and an AZ find with similar flow structures.
As a follow-up question; do these tell us anything other than orientation of a meteorite? Thank you. see link for pictures. Please all opinions welcome. Carl
