SSHADE/PaSSTEL: PlanetAry Surface Spectroscopy Toulouse Experimental Laboratory

Patrick Pinet & Yves Daydou
PaSSTEL database is aimed at characterizing the optical response of geological targets ranging from controlled powders to complex slab rock samples. It mainly consists of visible-near infrared bidirectional reflectance measurements performed on natural mineral solid solution samples, involving pyroxene and/or olivine minerals, with controlled grain size ranging from 45 µm to 2 mm, with six defined granulometric classes. Samples are derived from natural volcanic products with diverse contents of rock fragments, monocrystals and glass, various...
