Some few meteorites have "flow lines" but so do terrestrial rocks, both natural and man-made
Many people have told me that they think their rock is a meteorite because it has “flow lines.” Few meteorites have flow lines.
Flow lines and other flow-like features are common on meteorwrongs, however. The photos below were all sent to me by persons who enquired whether the object was a meteorite. Note that none of the objects has a fusion crust.
This is simple: If a rock does not have a fusion crust, then it does not, and cannot, have meteorite flow lines.
