Fig. 1.4 ( a ) 750 nm reflectance of a small area from southern Mare Crisium, ( b ) iron map derived
from Lucey's algorithm, and ( c ) iron map derived from PLS model. It can be seen that most of the
bright fresh craters are invisible in our iron map

Fig. 1.5 Statistical result of Fig. 1.4 ( a ) Lucey's result, corresponding to Fig. 1.4b ;( b ) our result,
corresponding to Fig. 1.4c . Both of them have obvious bimodal structure, the left peak represents
iron concentration in highland area, and the right peak represents iron concentration in mare area.
Iron peak in highland area is 9 wt% in our model and 8 wt% in Lucey's, while iron peak in mare
area is about 16.5 wt%, which is the same with Lucey's
