Claim:
1. A computer implemented method for displaying a mineral composition of a sample, comprising: illuminating a portion of the sample with a charged particle beam; generating, via one or more processors, a sample emission spectrum from detected emissions from the sample; fitting the sample emission spectrum with a plurality of candidate emission spectra, wherein each candidate emission spectrum comprises a combination of the emission spectra from a plurality of minerals in proportions that are determined by the fit to the sample emission spectrum; identifying an emission spectrum from among the plurality of candidate emission spectra based on a quality of fit to the sample emission spectrum, wherein the identified emission spectrum comprises a plurality of identified minerals in a respective plurality of identified proportions; assigning a plurality of colors respectively corresponding to the plurality of identified minerals; and rendering an image pixel corresponding to the illuminated portion of the sample by assigning the image pixel a definite color based on the plurality of identified minerals by blending the plurality of colors respectively corresponding to the plurality of identified minerals according to the respective plurality of identified proportions.
