This paper introduces especially geologic features of occurred feldspar druses in granite pegmatite veins of rock crystal and of rare metal minerals

and discribes 6 kinds of feldspar druse. They are pink potash feldspar druse

white potash feldspar druse

white petal like albite druse

white stair like albite druse

White sheaf like albite druse and transparent plate lile albite druse. These druses are not only mineral specimens for display

collection and ornament

but also theoretically significant in scientific research of the development of granite pegmatite

hot gas water solution

the extploration of mineral deposits and putting mineral resources to rational use.
