A - I would term the mere presence of flow lines as saying that the = meteorite was "flight marked" but not necessarily Oriented. B - I don't think that the absence of fusion crust would mean that a = specimen could not be Oriented. An example would be the famous "King of = Irons" Gibeon. In my opinion, Orientation refers to shape also. C- Yes, I believe that the elongation of regmaglypts is a sign of = possible orientation. When this is combined with a flat bottom with a = roll over rim the signs of Orientation are even more convincing. I think the real test of orientation is when you can look at the piece = and actually visualize the direction of flight. I have seen many photos = on ebay described as oriented where I ask myself - "Oriented in what = direction?" Orientation should be obvious to the casual observer or the term "flight = marked" should be used. Best Wishes to all..............

C: When thumbprints have a particular elliptical shape with a = depressed side and a rim on the other side, is it a sign of = orientation.?=20 Best regards Michel FRANCO Caillou Noir ------=_NextPart_000_0034_01C3BFB6.3EF061C0 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=3DContent-Type content=3D"text/html; = charset=3Diso-8859-1"> <META content=3D"MSHTML 6.00.2800.1276" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=3D#ffffff> <DIV>My opinion on your points...........</DIV> <DIV> </DIV> <DIV>A - I would term the mere presence of flow lines as saying = that the=20 meteorite was "flight marked" but not necessarily Oriented.</DIV> <DIV> </DIV> <DIV>B - I don't think that the absence of fusion crust would mean that = a=20 specimen could not be Oriented.
