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 anorthosite. Feldspars are also found in many types of sedimentary rocks.

Hys- teresis properties indicate that the domain state of magnetic inclusions in the feldspar crystals is single or pseudosingle domain while that of the groundmass is pseudosingle to multidomain. High resolution SEM and TEM analyses indicate that the magnetic inclusions are equant to slightly elongated and are 50 to 350 nm in size.

3. Magnetic separation Due to the magnetic properties of iron minerals, mica and garnet in feldspar ore, it can be separated from feldspar mineral by the external magnetic field. In general, the magnetic properties of iron minerals and mica in feldspar are weak, only by using high-intensity magnetic separator can get a good result.

What Type of Rock Is Magnetic? - Reference.com

Since it is so difficult to distinguish between Orthoclase, Sanidine, and Microcline, they may be simply called "Potassium Feldspar". Microcline sometimes forms in association with Albite or other Plagioclase feldspar in alternating patterns, and forms a feldspar rock known as Perthite.

Feldspar and pyroxene make basalt. Or, if feldspar gets in contact with another rock called pyroxene, those two rocks combine to make basalt. Since the Stone Age, people have used basalt for grindstones. Basalt is a very hard rock too. One of the earliest trade goods was basalt for grindstones, carried down rivers or on donkeys.
