The variable UV-fluorescence of minerals is well known, and this is attributed to some defects in crystallographic structure or some admixtures, e.g. REE elements. So far, UV-fluorescence has not been applied to describe the nature of meteorites. The plates of forty-five meteorites were examined in three simultaneous emission spectra under an epi-fluorescence microscope. Meteorites were characterized quantitatively according to twelve colours of fluorescence, arbitrarily identified. A numerical method of non-metric multidimensional scaling was used to put colour characteristics as well as the meteorites into an ordination space. Each colour characteristic carries its own information independent of the others. NWA 4039, Bilanga, Gujba and NWA 5437 are extremes in the ordination space. Sahara 560 and NWA 791 expressed very poor and very rich fluorescence, respectively. UV-fluorescence can be a good screening method to quickly distinguish space minerals with crystallographic defects and/or those which are contaminated by REE elements. In subsequent research, other more advanced methods will have to be used.
