feldspars's Usage Examples:

The resulting intergrowth of the two feldspars is called perthite.

foid-bearing or feldspathoid rocks, meaning rocks predominantly containing feldspars but no quartz, are also granitoids.

include quartz, muscovite, orthoclase, and the sodium-rich plagioclase feldspars (albite-rich).

Green and greenish-blue varieties of potassium feldspars that are predominantly triclinic are designated as amazonite.

are found in feldspars.

The two most common feldspars in the ceramic.

Perthite is used to describe an intergrowth of two feldspars: a host grain of potassium-rich alkali feldspar (near K-feldspar, KAlSi3O8, in composition).

Sericite is produced by the alteration of orthoclase or plagioclase feldspars in areas that have been subjected to hydrothermal alteration typically.

Communities describes it as being made of selected clays sometimes mixed with feldspars and varying amounts of other minerals, and white or light-colored (i.

Although aluminium substitutes extensively for silicon in silicates such as feldspars and amphiboles, the substitution occurs only to a limited extent in most.

These feldspars are known as ternary because they contain significant components of all three endmember feldspars.

Alkali feldspars (potassium feldspars) Microcline – KAlSi3O8 Orthoclase – KAlSi3O8 Anorthoclase – (Na,K)AlSi3O8 Sanidine – KAlSi3O8 Plagioclase feldspars Albite.

The feldspathoids are a group of tectosilicate minerals which resemble feldspars but have a different structure and much lower silica content.

that has an approximately equal proportion of orthoclase and plagioclase feldspars.

occurs in pegmatite deposits and is easily mistaken for albite and other feldspars.

Oligoclase is a rock-forming mineral belonging to the plagioclase feldspars.

classed as a member of the feldspathoid group of minerals; the alkali feldspars that are poor in silica.

minerals present in this type of rocks are feldspars, including both potassium and plagioclase feldspars.

) miscibility gaps in the plagioclase feldspars.

classification for sandstones based on the relative abundances of quartz (Q), feldspars (F), and rock fragments (R).
