The spectral energy distributions of 16 AGB stars in the LMC are fitted. The 6 known oxygen-rich stars are well fitted with silicate dust. Due to the completely different absorption properties of silicate and carbonaceous dust we argue that of the 10 stars of unknown spectral type, 1 is probably O-rich while the other 9 are probably C-rich.

The Period-Luminosity relation is discussed. Both the O- and C-rich LPVs in this study appear to lie on extensions of P-L relations derived for stars with much shorter periods.
