It's described as "an 11.1 g piece of Norton County (ASU#523)" where "The large enstatite crystals fluoresce bright yellow." Quite an eyeful. This is an oddball meteorite, I'm guessing, as I haven't seen pictures of any other meteorites displaying fluorescent color values. Does this bode well for other fluorescent meteorites being found? I mean, are the scientists really looking and checking for fluorescent color values in meteorites on a systematic basis? If not, they may be missing the boat. If you look closely at this picture you may be able to detect, as I do, that there apparently are other possible fluorescent color values happening, as well. I am referring to the noticable blue/green colored fluoresent values below and to the right of the yellow colored enstatite and to the upper left of the enstatite area, also. To my understanding, these may indicate additional minerals with other fluorescent color values reacting to utlraviolet light, too. It's unfortunate that the person who took this picture did not take the time and spend the effort to look carefully at their resulting picture. I wonder what wavelength ultraviolet was used, although I guess it was probably shortwave. If so, they may not have exposed the specimen to midwave and longwave ultraviolet wavelengths, as well, consequently denying themselves (and the rest of us!) valuable ultraviolet reactive fluorescent color value information. Is this simply a situation of sloppy science rearing it's ugly head? Or does it indicate that ignorance is truly bliss, after all? Yours for the light, Dave Gunning Received on Sat 02 Oct 2010 04:29:52 AM PDT |
