This 10x magnification photograph is a thin section of an Arkosic Sandstone. Note that it is made of of rounded grains, cemented together by a fine matrix of opaque minerals (the red brown color of the rock suggests these opaques may be some sort of iron oxide mineral). Arkosic Sandstones contain high abundances of Feldspar as well as Quartz.

Sep 15, 2011Dichroic minerals can be a little bit tricky to identify in thin section. Because thin sections essentially represent a 2D slice of a 3D mineral, dichroic minerals may or may not display pleochroism in thin section. If the thin section displays two crystal axes which are distinct, then the mineral will display pleochroism.
