Feldspar minerals make up over 50% of Earth''s crust.

Feldspar has been derived from a german word which means a rock that does not contains ore. It is made up of group forming tectosilicate minerals that almost covers 60% of the earth''s crust. Feldspathic refers to the material which contains feldspar. Rock is almost formed of calcic plagioclase feldspar is known as anorthosite.

Aug 10, 2019· This mineral is often called potassium feldspar or Kfeldspar because potassium always exceeds sodium in its formula. Potassium feldspar comes in three different crystal structures that depend on the temperature it formed at. Microcline is the stable form below about 400 C. Orthoclase and sanidine are stable above 500 C and 900 C, respectively.

Plagioclase: the white or chalky looking grain is the common feldspar, plagioclase. Plagioclase is the most common mineral in igneous rocks. The illustration to the left shows a large chalky white grain of plagioclase. The chalky appearance is a result of weathering of plagioclase to clay and this can often be used to aid in identification.

Plagioclase Wikipedia

Plagioclase is a series of tectosilicate (framework silicate) minerals within the feldspar group. Rather than referring to a particular mineral with a specific chemical composition, plagioclase is a continuous solid solution series, more properly known as the plagioclase feldspar series (from the Ancient Greek for "oblique fracture", in reference to its two cleavage angles).
