Almost all quartz grains present wave extinction, and many of the smaller quartz grains may result from grain nucleation. Relative amounts of quartz and feldspar are difficult to estimate due to visual similarity, but quartz likely occupies only 20 to 30 percent of slide area. Perthitic textures are rarely present in feldspars. Biotite is the ...

Granite is a natural source of radiation, like most natural stones. Potassium-40 is a radioactive isotope of weak emission, and a constituent of alkali feldspar, which in turn is a common component of granitic rocks, more abundant in alkali feldspar granite and syenites. Some granites contain around 10 to 20 parts per million (ppm) of uranium.
