Figure 27. This figure shows <strong>the</strong> true color image (A) and <strong>the</strong> associated MF verses<br />
infeasibility scatterplot (C) being utilized <strong>to</strong> analyze an imagery derived<br />
endmember and see what type of score distribution is associated with areas<br />
of <strong>the</strong> highest pixel concentration. In B, Yellow ranges are areas with low<br />
infeasibility and high MF scores highlighted in <strong>the</strong> scatterplot, and represent<br />
<strong>the</strong> most likely areas <strong>for</strong> target mixtures. The range associated with <strong>the</strong>se<br />
areas contains 30–76 % of <strong>the</strong> endmember.<br />
Figure 28 illustrates some of <strong>the</strong> imagery-derived endmembers utilized. Figure 29<br />
illustrates one of <strong>the</strong> imagery derived primary soil components identified using <strong>the</strong> USGS<br />
mineral spectral library as a possible zunyite mixture. Zunyite is a mineral common <strong>to</strong> <strong>the</strong><br />
San Juan County area of Colorado and is associated with <strong>the</strong> Zunyite Mine in Anvil<br />
Mountain of <strong>the</strong> Red Mountain District proving it <strong>to</strong> be a feasible match <strong>for</strong> <strong>the</strong> imagery<br />
area (http://www.merriam-webster.com, http://colorado.home<strong>to</strong>wnloca<strong>to</strong>r.com).<br />
