Alkali feldspar makes up 35 to of the total feldspar content. Rhyolite may contain some larger crystals know as phenocrysts.

Feldspar

Feldspar occurs mostly as white, green or red-brown, ranging from flesh colour to the colour of brick. A special type of feldspar is extracted from pegmatites in very small quantities (50-100 t per year) at a mine near Buckingham, Québec. This feldspar has a glassy lustre, ...

Feldspar vs. Quartz: What's the Difference? 5 Crucial Signs

Amphibole – both feldspar and quartz; Sedimentary Rocks with Quartz and Feldspar. Many sedimentary rocks are formed from the shells of animals in the ocean. These types of sedimentary rock would contain little or no quartz or feldspar. Since quartz is the most abundant mineral on earth, it is found in more sedimentary rocks than …

Alkali Feldspar

Alkali feldspars constitute a solid-solution between K-feldspar or orthoclase molecule (Or) and albite (Ab), which represents also the sodic end-member of the plagioclase series. Anorthite (Ca[Al 2 Si 2 O 8]; An) is present in small quantities in alkali feldspars, usually constituting less than 5% of the solid solution and predominantly found in Na-rich alkali …

Rhyolite

Rhyolite is a fine-grained or glassy igneous rock chemically and mineralogically the volcanic equivalent of granite. The name was originally applied to such rocks by von Richthofen (1860, see Johannsen, 1932) on account of the frequently displayed flow banding (prefix rhyo-, from Greek rhyox, stream of lava). Liparite (Roth, 1861 see …
