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,
