Petrology of Nepheline Syenite Pegmatites in the Oslo Rift,
2010年10月21日 Syenite and nepheline syenite pegmatites are relatively common in the Larvik Plutonic Complex (Dahlgren, 2010), and can be grouped in three main suites. Miaskitic pegmatites with zircon, titanite, pyrochlore and zirconolite (‘polymignite’), known as the eastern type, as they are mainly found in the eastern part of the complex.
Notes. Nepheline Syenite is an anhydrous sodium potassium alumino silicate. Although feldspar-like in its chemistry, mineralogically it is an igneous rock combination of nepheline, microcline, albite and minor minerals like mica, hornblende and magnetite.The Canadian manufacturer describes it as “a naturally occurring, silica deficient sodium-potassium alumina silicate.”
