Does ternary feldspar constrain the metamorphic conditions of …

WebFeldspar minerals are essential components in igneous, metamorphic and sedimentary rocks, to such an extent that the classification of a number of rocks is based on feldspar content. The mineralogical composition of most feldspars can be expressed in terms of the ternary system Orthoclase (KAlSi3O8), Albite (NaAlSi3O8) and Anorthite (CaAl2Si2O8). WebEach compositional group contains only a single feldspar compositional trend with a general tendency of more evolved composition for microlites than for euhedral phenocrysts, consistent with the phase relation for single solid solutions in the system albite–orthoclase and with the ternary feldspar phase relations in the system … the 157th regiment
