ASSOCIATED MINERALS:

Adularia, albite, amazonite, andesine, anorthite, azulicite, bytownite, labradorite, microcline, moonstone, oligoclase, orthoclase, paracelsian, sanidine and sunstone.

ASTROLOGICAL SIGNS:

Aquarius.

CHEMICAL STRUCTURE:

The general formula, for the common feldspars, is XAl(1-2) Si(3-2) O8 . The X in the formula can be sodium, Na and/or potassium, K and/or calcium, Ca. When the cation in the X position has a positive one (+1) charge such as with sodium or potassium, then the formula contains one aluminum and three silicons ions. If the formula contains the positive two (+2) cation calcium, then the formula will contain two aluminums and only two silicon ions. This substitution keeps the formula balanced, because aluminum has a charge of positive three (+3) and silicon has a charge of positive four (+4). Basically, the more calcium in the crystal, the more aluminum that will be needed to balance the charge.
