Feldspar- Varieties,Formation,Sources,Properties,Test,Tips

Feldspars, the most important of the rock-forming minerals, are integral constituents of almost every igneous rock; in fact, it is the color of the feldspar that usually determines the color of the igneous rock of which it is a part. For example, orthoclase, which makes up about 90% of the volume of a granite, makes the rock pink when it is ...

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 ...
