Where I could to get a silicate infrared thermal mineral spectral library ?

The eletromagnetic energy comprises : visible; near-infrared ;swir infrared and thermal infrared (distal) infrared .We don´t have thermal (TIR) infrared spectral library, because spectral library Aviris Sensor ranges the visible to Swir and not the thermal (TIR) range. The thermal silicate spectral signatures are very import to identify and classify granites, as well bodies associated to mineralisations.I intend to import the spec lib to ENVI program.

Update:

Thanks to all. I have contacted University of Arizona using the website:

http://tes.la.asu.edu./

I found out a Thermal (TIR) spectral lIbrary in http://tes.la.asu.edu.,/ that can be imported to ENVI. They informed me that I could use the spec lib only a time .I could see the albite spectrum plotted but I couldn´t import it.Now they aren´t showing the data to me.Please, what is the Bob complete name and email or department?

As to the NASA links, they have only the VNIR and SWIR spectral library.They don´t allow to acess theTIR spectral library .Anyway thanks.

Update 2:

I have downloaded feldspars and quartz thermal(TIR) spectral signatures from http://tes.la.asu.edu./

The signatures os this spectral library are similar to signatures in the papers about TIR, except for the x-axis values in plot, that aren´t 8-12 um(micrometros) but 0 to 2,000 unknown units.What happened?? The spectral library building was carried out in ENVI.Thanks...

    The JPL ASTER spectral library is probably your best bet:

    http://speclib.jpl.nasa.gov/

    Free, easy to get and import into ENVI (I've done it many times).

    Also, check out the ASU library:

    http://speclib.asu.edu/

    You have to create a login to get these, but they will also import into ENVI.

    EDIT:

    Try the ASTER/JPL site again. They DO have spectral data in the TIR - all the way out to 25 microns, in fact!

    Send me a message if you have questions. I have published many papers with these TIR spectral data.

    Check with the University of Arizona, Bob Downs in particular. He is the resident crystallographer.
