About PhonoliteHide

Phonolitic rocks, with felsics comprising 60-90% foids and alkali feldspar/total feldspar >0.9.

The extrusive or fine grained equivalent of nepheline syenite. The principal mineral is anorthoclase or sanidine. Other major minerals may be nepheline, aegirine and diopside, usually with other feldspathoidal minerals such as sodalite or hauyne. Accessories include apatite and sphene.

Classification of PhonoliteHide

Phonolite appears in field 11 in the QAPF diagram.^TAS

Sub-divisions of PhonoliteHide

Mineralogy of PhonoliteHide

Essential minerals - these are minerals that are required within the classification of this rock:
Feldspar > Alkali FeldsparFeldspar Group minerals rich in Potassium or Sodium.
Non-essential minerals - these minerals are common, sometimes major components, but are not always present:
Feldspathoid > Haüyne(Na,K)3(Ca,Na)(Al3Si3O12)(SO4,S,Cl)
Feldspathoid > NephelineNa3K(Al4Si4O16)
