What is the formula for normal feldspar and rare gold? ?
I can't find the formula for rare gold and for feldspar, the formula is written weirdly.
THANKS =D
Gold is an element, so its chemical symbol is Au.
There are numerous common varieties of feldspar: orthoclase and plagioclase are the most common.
Orthoclase is KAlSi3O8
Plagioclase forms a series from a sodium-rich end member (albite) to the calcium-rich end member (anorthite). The formula for albite is NaAlSi3O8 and anorthite is CaAl2Si2O8.
