Thanks Walt... It came up in this NR: Message 3937719 I wasn't sure what it was... Why the 'ell don't they just call it magnetite or pyrhotite... Those two I know... Learned all about it when I took that Gold Pannin' course up in Gr. Prairie back in '80... Found quite a bit of it (magnetite) in the Peace over south of Valleyview way... Unfortunately that's all I found...:-( ...ed

Walt, The difference between the two would be wavelength or frequency of the magnetic anomalies. The size and shape of the anomalies. Magnetic sands have very short wavelengths which indicate a very shallow depth to source and very limited depth extent. In a survey they appear as spikes which may or may not form a coherent pattern. They almost always coincide with the local topography (a dead giveaway) "True" geological features have varying wavelengths (always longer) indicating some depth to source and some measurable depth extent. The two are very easily distinguished and separated. 1King
