http://www.marmet-meteorites.com/id12.html WebWe have compared several FT–IR spectroscopy techniques (open path transmission spectroscopy and diffuse reflectance spectroscopy of powders; microspectroscopy of single grains and powders and ATR spectroscopy of thin sections) to determine their utility for the direct measurement of the mid-IR spectra of small amounts of extraterrestrial grains.
The melilite structure consist of pairs of fused T O 4, where T may be Si, Al, B, in bow-tie form. Sharing one corner, the formula of the pair is T2 O 7. These bow-ties are linked together into sheets by the B cations. The sheets are held together by the A cations, most commonly calcium and sodium.
