Feldspar - an overview | ScienceDirect Topics

D.G.F. Long, in Sediment Provenance, 2017 5.1.2 Feldspar. Feldspar, along with patches of epimatrix (patches of clay replacing feldspar: Dickinson, 1970), form an average of 2.4% of framework of conglomerate and 9.7% of grains in sandstone from the Tantalus formation.This is significantly lower than in the Tanglefoot formation where they form 25% of framework in the conglomerate and 33.4% of ...

GMS - Zoning in Minerals

Feldspar can also be chemically zoned. Plagioclase feldspar grows in igneous environments and crystals which grow early in a cooling magma contain more calcium than those formed at the end of crystallization, which are enriched in sodium. This is predicted by the Bowen's Reaction Series.
