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 ...

The thermal decomposition of albite may be attributed to a high iron oxide content. It is well known that in silicate melts iron may occur in both oxidation states, as Fe 2+ and Fe 3+ ions [8,9], of which Fe 2+ acts as a network modifier (flux) and thereby lowers the melting point and viscosity [10,11].

Both cataclasis of quartz and feldspar grains and enrichment of phyllosilicates result in grain size reduction within the deformation bands. The measured reduction in porosity of up to 20% is in some cases associated with a permeability reduction, reflected in the retention of iron-oxide rich fluids along deformation bands.
