Whitmore and Strom ◀ Angular K-feldspars in ancient sandstones ▶ 2018 ICC 635 Figure 7. Examples of thin sections from sandstones occurring in Colorado, Wyoming and Utah. Both angular and rounded grains can be found in the sandstones. Some of the mineral grains are labeled as follows: (K) K-feldspar, (M) muscovite and (D) dolomite. Quartz is white. The blue color is epoxy. The samples have been stained so K-feldspar is yellow. The K-feldspar grains in the LLS-02 sample dissolved at some point in the history of the rock, but the angular outline of the grain still remains.
