Sintering of feldspar rocks from czech quarries

Feldspars are silicoaluminates of alkaline and alkaline-earth metals. Feldspars create about 60% of earth and form part of rocks as fundamental mineralogical components. From the chemical point of view, feldspars are divided into the following fundamental types: Potassium feldspars (K-feldspars) K(AlSi 3O 8)Orthoclase, Microcline,

Feldspars crystallize from magma as veins in 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 anorthosite. Feldspars are also found in many types of sedimentary rocks.

Feldspar. It is the single most abundant mineral group on Earth. They account for an estimated 60% of exposed rocks, as well as soils, clays, and other unconsolidated sediments, and are principal components in rock classification schemes. The minerals included in this group are the orthoclase, microcline and plagioclase feldspars.

Feldspars in Igneous Rocks

Feldspars define better than any other mineral group the three stages in the evolution of igneous rocks, the magmatic growth, the subsolidus transformation and the deuteric alteration stages. Feldspars in igneous rocks show the largest variation in chemical composition, form the basis for the classification of these rocks and have played a dominant role in the development of ideas on differentiation.

Feldspars are divided into two major gropus including alkali-feldspars and plagioclase. You have to distinguish between brittle and ductile deformation of feldspars and you have to distinguish between alkali feldspar group (microcline, orthoclase, sanidine) and plagioclase group (albite - anorthite series).

Igneous Rock Classification

Igneous Rocks are classified is several ways, and methods of classification have evolved a lot over the past 100 years. Each classification is useful for a certain purpose and reflect a particular way of looking at igneous rocks. All rock classifications are based on two criteria, however, mineral content of the rock, and texture (grain size).
