Abstract. The feldspars are among the most important, abundant, and widely occurring minerals to be found in various types of rocks. They are of direct concern to the soil scientist because (1) they are important primary minerals from which soil components (especially clay minerals) are formed during the weathering cycle; (2) they are direct sources of some plant nutrients; and (3) they are ...

Feldspar. Geologists see feldspar as a mineral and classify feldspars as mainly as albite, microcline, orthoclase and anorthite. However, for use in glazes, we can view feldspars as 'warehouses of oxides' ( because they supply K 2 O, Na 2 O, Al 2 O 3 and SiO 2 to the glaze melt).

 · Illite and chlorite dominate the mesogenetic clay minerals and usually grow at the expense of eogenetic clay minerals and detrital feldspars and lithic grains. Mesogenetic illite and chlorite can result from widely different reactants and processes.

Orthoclase feldspar (KAlSi 3 O 8), also called potassium feldspar or Kspar, is made of silica, aluminum, and potassium. Quartz and orthoclase feldspar are felsic minerals. Felsic is the compositional term applied to continental igneous minerals and rocks that contain an abundance of orthoclase feldspar. Another feldspar is plagioclase with the formula (Ca,Na)AlSi

The same is true for all Feldspar minerals that crystallize in the triclinic system their third angle of symmetry is asymmetrical by only a fractional amount. This is the reason all Feldspar crystals, even those crystallizing in different systems, have crystals that can be very similar in appearance. This is also the reason why Orthoclase and Microcline are often regarded as a single mineral ...
