Arkose – Beautiful Sedimentary Rock

Arkose Sedimentary RockI usually tell you when I think some rocks have unique features and are just plain cool.  Arkose is perhaps, one of my favorite sedimentary rocks because it is just plain pretty.  

Arkose is a beautiful sedimentary rock that is typically gray, pink or red.  This coarse-grained rock forms when igneous rocks break apart and the pieces travel to a river, lake or ocean.  These smaller pieces are glued (cemented) together with quart or calcite.  The major mineral in arkose is feldspar and the minor minerals include quartz and mica.  The color of the arkose is largely controlled by the feldspars which are common in gray, white and pink.  Arkose is found worldwide and is sometimes used for building materials.

Mini Me Geology offers samples of arkose both individually and in the My Rockin’ Collection! Sedimentary Rocks deluxe rock kit.  Get your sample of Arkose today at!
