Density of albite
Did you know?
WebDensity of feldspar is 2.56 (K-feldspar) and ranging from 2.62-2.78 (albite to anorthite) which makes them relatively light-weight minerals among other silicate rock-forming minerals. Only Ba-feldspar (3.37) is clearly among the heavy minerals. Feldspars are so common because their constituent elements (Si,Al,O,Na,K,Ca) are ubiquitous. Albite is a plagioclase feldspar mineral. It is the sodium endmember of the plagioclase solid solution series. It represents a plagioclase with less than 10% anorthite content. The pure albite endmember has the formula NaAlSi 3O 8.
