Alkali feldspar granite Alkali feldspar granite Alkali feldspar granite, some varieties of which are called 'red granite', is a felsic igneous rock and a type of granite rich in the mineral potassium feldspar (K-spar). It is a dense rock with a phaneritic texture. The abundance of K-spar gives the rock a predominant pink to reddish hue; peppered with minor amounts of black minerals. As shown in the QAPF diagram, alkali feldspar granite contains between 20% - 60% quartz. Less quartz content would lead to "quartz alkali feldspar syenite". More than 90% of the total feldspar content is in the form of alkali feldspar.
Granite spiny lizard females have distinct yellow-tan transverse bands on their body and tail. Additionally, the male has deep-blue ventral patches on its chest and throat and femoral pores. The granite spiny lizard is a colorful species that can be observed perched atop boulders from considerable distance. This species is primarily associated with rocky hillsides and outcrops. They have been known to try to mate with other members of their sex. Granite spiny lizard The granite spiny lizard (Sceloporus orcutti) is a species of phrynosomatid lizard.
