Fig. 2.5 ( a ) RELAB spectra of plagioclase, clino/ortho pyroxene and olivine minerals. ( b )Low-,
medium- and high-Ti basaltic end member spectra from RELAB

(Bokun et al. 2008 ). Pure materials can be measured under controlled conditions in
the laboratory, but for remotely sensed data, multiple components possibly will be
included in one measurement (pixel) causing spectral mixing.

2.4 Results and Discussion

Based on the spectral profiles, we are able to discriminate the difference between
the ortho- and clinopyroxene such as Mg, Fe, and Ca pyroxenes. Based on the TiO 2
estimation, spectral profiles, and linear spectral unmixing, the following results were
obtained and discussed herewith.
