What is the chemical name of gneiss?
Because gneiss can be composed of so many different materials (though micas and platy minerals won’t be included, as well as some others), there is no chemical formula for it. There are a wide variety of chemicals actually found in gneiss, including silicon and many different metals. About the best we can do is to characterize gneiss as being composed of albite, biotite, magnetite, or some other material, or groups of these materials.
