Hello List,
Have just purchased a nice slice of a low TKW LL3. NWA 2461.
The met bulliten lists Fayalite (mol%): 26.5±2.5
Ferrosilite (mol%): 12.5±7
The Met Bulliten also gives an official classification of an LL3. The
encyclopedia of meteorites states that an LL3 should have a Fs value of 32-40
so how can this be grouped as an LL3? The Fa value fits.
Any help would be gratly appreciated.
Cheers,
Mike Tettenborn
