WebMinerals within a solid solution group can have very different color characteristics in hand sample (as shown in Figure 2.6.6) and under the microscope. Figure 2.6.4. Garnet (pink) and clinopyroxene (green) under plane polarized light. Eclogite, California, Ward’s collection sample, 40x total magnification. Figure 2.6.5. WebThe dark mineral (usually biotite or hornblende) will - according to Bowens - crystallize first (and sure enough usually has well-formed crystalline shapes). The feldspar will be less perfect (called "subhedral" because it sometimes ran into some of the dark mineral and only has some of its faces). And the quartz? Well, it falls at the bottom ...
