Whitmore and Strom ◀ Angular K-feldspars in ancient sandstones ▶ 2018 ICC 637 Figure 9. Examples of thin sections from sandstones in Arizona, Utah and New Mexico. Both angular and rounded grains can be found in the sandstones. Some of the mineral grains are labeled as follows: (K) K-feldspar, (Ka) Kaolinite, and (M) muscovite. Quartz is white. Calcite is pink. The blue color is epoxy. The samples have been stained so K-feldspar is yellow and calcite is pink. Note that in GLO-06 the K-feldspar has dissolved, yet its angular outline remains. In GLO-02 and GLO-06 some K-feldspar has been replaced with kaolinite with the angular shape of the K-feldspar remaining.
