|---|---|
| feldsparnoun | (mineralogy) Any of a large group of rock-forming aluminosilicate minerals containing potassium, sodium, or calcium that, together, make up about 60% of the Earth's outer crust. |
| felsparnoun | Alternative spelling of feldspar. [(mineralogy) Any of a large group of rock-forming aluminosilicate minerals containing potassium, sodium, or calcium that, together, make up about 60% of the Earth's outer crust.] |
| feldspathoidnoun | (mineralogy) Any of a small group of igneous, plutonic, and volcanic minerals formed in magma that did not contain enough silica to satisfy all the chemical bonds. Feldspathoids are silica-poor variants of the feldspar group. |
| potassium feldsparnoun | (mineralogy) Any of several alkaline feldspars containing potassium aluminium silicate, KAlSi₃O₈ |
| felspathoidnoun | Alternative form of feldspathoid. [(mineralogy) Any of a small group of igneous, plutonic, and volcanic minerals formed in magma that did not contain enough silica to satisfy all the chemical bonds. Feldspathoids are silica-poor variants of the feldspar group.] |
| alkalifeldsparnoun | Alternative form of alkali feldspar. [(geology) Any alkaline feldspar.] |
| orthoclasenoun | (mineralogy) Potassium aluminum silicate, KAlSi₃O₈, a common feldspar of igneous, plutonic, and metamorphic rocks. Orthoclase is the main feldspar of pegmatite occurrences, where it is most commonly flesh-colored. Orthoclase is used in the ceramic and glass industries and as a decorative gravel. |
| anorthoclasenoun | (mineralogy) Any of a group of feldspars being mixed sodium and potassium aluminosilicates. |
| plagioclasenoun | (mineralogy) Any of a group of aluminum silicate feldspathic minerals ranging in their ratio of calcium to sodium. |
| microclinenoun | (mineralogy) A common feldspar of igneous, plutonic, and metamorphic rocks, made of potassium aluminum silicate, with the chemical formula KAlSi₃O₈. |
| foidnoun | (incel slang, derogatory, offensive) Clipping of femoid. [(incel slang, derogatory, offensive) A woman.] |
| aluminosilicatenoun | (inorganic chemistry) Any of many silicate minerals, such as feldspar and zeolite, in which a proportion of the Si⁴⁺ ions are replaced by Al³⁺, the excess negative charge being balanced by extra sodium, potassium or calcium ions. |
| pulaskitenoun | (mineralogy) A massive course-grained rock composed chiefly of feldspar with some other minerals such as hornblende and biotite. |
| nephelinenoun | (mineralogy) A feldspathoid mineral of silica-poor igneous, plutonic and volcanic rocks. Chemically, nepheline is a plagioclase feldspar with insufficient silica to satisfy the chemical bonds. Because of the unfilled bonds, nepheline weathers rapidly and can only be seen as inclusions in freshly broken rock. |
| felsitenoun | (mineralogy) A fine grained volcanic extrusive rock, generally light in color, composed of felsic minerals. |
| oligoclasenoun | (mineralogy) A plagioclase feldspar, the second member of the Albite-Anorthite solid solution series. Primarily found as small crystals in impure marble. Oligoclase contains a small amount of calcium substituting for some of the sodium in its formula. Oligoclase with reddish-golden inclusions found in Norway and Canada is called sunstone. |
| potash-feldsparnoun | (obsolete, mineralogy) potassium feldspar |
| potash-felsparnoun | (obsolete, mineralogy) potassium feldspar |
| chesterlitenoun | (mineralogy) A variety of microcline from Chester County, Pennsylvania. |
| tectosilicatenoun | (mineralogy) Any of various silicate minerals, mostly aluminosilicates, with a three-dimensional framework of silicate tetrahedra with SiO₂ or a 1:2 ratio, making up the greater part of Earth's crust. |
