Feldspar: Feldspar, any of a group of aluminosilicate minerals that contain calcium, sodium, or potassium. Feldspars make up more than half of Earth's crust, and professional literature about them constitutes a large percentage of the literature of mineralogy.

A mineral is a nonliving natural substance of a definite chemical composition. A mineral like manganese may help keep you healthy; a mineral like a diamond may help keep you sparkly.

But from the viewpoint of mineralogy, it is feldspar that is the most common mineral. In fact feldspar makes up nearly 60% of the Earth's crust. Feldspar is a group of minerals distinguished by the presence of aluminum silicates with potassium, sodium, calcium and barium.
Etymology. The name feldspar derives from the German Feldspat, a compound of the words Feld, "field", and Spat, "a rock that does not contain ore". The change from Spat to -spar was influenced by the English word spar, meaning a non-opaque mineral with good cleavage.

Feldspar is by far the most abundant group of minerals in the earth's crust, forming about 60% of terrestrial rocks. Most deposits offer sodium feldspar as well as potassium feldspar and mixed feldspars.
Feldspar - Chemical composition: All the rock-forming feldspars are aluminosilicate minerals with the general formula AT4O8 in which A = potassium, sodium, or calcium (Ca); and T = silicon (Si) and aluminum (Al), with a Si:Al ratio ranging from 3:1 to 1:1.

The Nesosilicate Subclass (single tetrahedrons). The simplest of all the silicate subclasses, this subclass includes all silicates where the (SiO4) tetrahedrons are unbonded to other tetrahedrons.

Potassium (K) is the third major essential macronutrient for plant growth. The concentrations of soluble potassium in the soil are usually very low and more than 90% of potassium in the soil exists in the form of insoluble rocks and silicate minerals.
