- Sodium occurs abundantly as nitrate (NaNO_ {3}) in Chili saltpetre, and as silicate in various minerals, such as albite (or soda-felspar).
- In chemical composition and in optical and other physical characters it is thus much nearer to the anorthite end of the series than to albite.
- It depends on the felspar present -- _i. e._, whether it is orthoclase, oligoclase, or albite -- whether the soil will be rich in potash or not.
- Those yielded by orthoclase must generally abound in potash, while albite and labradorite, containing little or none of that element, must produce soils in which it is deficient.
- Basically, a process called metamorphism caused the basalts in Shenandoah to recrystallize with new minerals, such as chlorite, epidote, and albite, which help give the rocks their greenish hue.

- There are, for instance, several different minerals commonly classified under the name of felspar, which have been distinguished by mineralogists by the names of orthoclase, albite, oligoclase, and labradorite; and there are at least two sorts of mica, two of hornblende, and many varieties of zeolites.
- They are divisible into two great classes, which have received the names of diorite and dolerite, the former a mixture of albite and hornblende, the latter of augite and labradorite, sometimes with considerable quantities of a sort of oligoclase containing both soda and lime, and of different kinds of zeolitic minerals.
