Feldspar Encyclopedia

Feldspar. Feldspar is the most common mineral on Earth, constituting approximately 60% of the crust.It forms directly from cooling magma and is a major component of granite and most other igneous rocks.. The term feldspar actually covers a whole family of minerals, all of which consist of a framework of aluminum, oxygen, and silicon atoms plus an additive, usually potassium, sodium, or calcium.

What is Feldspar? Industrial Minerals Association

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. Feldspars are primarily used in industrial applications for their alumina and alkali content.

Feldspar Distinctions, Characteristics & Identification

Aug 10, 2019· This mineral is often called potassium feldspar or K-feldspar 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.

Feldspar Identification of specific feldspars Britannica

Feldspar Feldspar Identification of specific feldspars: Alkali feldspars can often be distinguished from plagioclase feldspars because most grains of the latter exhibit albite twinning (see above Crystal structure), which is manifested by parallel lines on certain cleavage surfaces, whereas grains of alkali feldspars do not. This criterion is not, however, absolute; some plagioclase

Feldspar Wikipedia

Feldspars (K Al Si 3 O 8 Na Al Si 3 O 8 Ca Al 2 Si 2 O 8) are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight.. Feldspars crystallize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as
