Read MoreFeldspar is the name of a large group of rock-forming silicate minerals that make up over 50 of earths crust. 1 they are found in igneous, metamorphic, and sedimentary rocks in all parts of the world. feldspar minerals have very similar structures, chemical compositions, and physical properties. common feldspars include orthoclase kalsi3o8, albite naalsi3o8, and anorthite caal2si2o8.
Read MoreTo appreciate the importance of feldspar as a rock-forming mineral, lets consider its abundance in earths crust. most of earths continental crust is made up of igneous rocks such as granite, diorite, and granodiorite. feldspars are also important constituents of gabbro and basalt, which are the primary types of rock in earths oceanic crust. the accompanying chart shows how these rocks are made up mostly of feldspar minerals. as these igneous rocks are weathered and metamorphosed, their feldspar minerals become components of sediments, sedimentary rocks, and metamorphic rocks.

Read MoreFeldspars are hard minerals, all of them with a hardness of 6 on the mohs scale. this lies between the hardness of a steel knife 5.5 and the hardness of quartz 7. in fact, feldspar is the standard for hardness 6 in the mohs scale.
Read MoreFeldspars usually are white or nearly white, though they may be clear or light shades of orange or buff. they usually have a glassy luster. feldspar is called a rock-forming mineral, very common, and usually makes up a large part of the rock. in sum, any glassy mineral that39s slightly softer than quartz is very likely considered a feldspar.
Read MoreThe main mineral that might be confused with feldspar is quartz. besides hardness, the biggest difference is how the two minerals break. quartz breaks in curvy and irregular shapes conchoidal fracture. feldspar, however, breaks readily along flat faces, a property called cleavage. as you turn a piece of rock in the light, quartz glitters and feldspar flashes.
Read MoreOther differences quartz is usually clear and feldspar is usually cloudy. quartz appears in crystals more commonly than feldspar, and the six-sided spears of quartz are very different from the generally blocky crystals of feldspar.
Read MoreFor general purposes, like picking granite for a countertop, it doesn39t matter what type of feldspar is in a rock. for geological purposes, feldspars are quite important. for rockhounds without laboratories, it39s enough to be able to tell the two main types of feldspar, plagioclase pladge-yo-clays feldspar and alkali feldspar.
Read MoreAlkali feldspar also called potassium feldspar or k-feldspar has a color range from white to brick-red, and it39s typically opaque. many rocks have both feldspars, like granite. cases like that are helpful for learning to tell the feldspars apart. the differences can be subtle and confusing. that39s because the chemical formulas for the feldspars blend smoothly into each other.
Read MoreWhat is common to all the feldspars is the same arrangement of atoms, a framework arrangement, and one basic chemical recipe, a silicate silicon plus oxygen recipe. quartz is another framework silicate, consisting only of oxygen and silicon, but feldspar has various other metals partly replacing the silicon.
Read MoreThe basic feldspar recipe is xal,si4o8, where x stands for na, k, or ca. the exact composition of the various feldspar minerals depends on what elements balance the oxygen, which has two bonds to fill remember h2o. silicon makes four chemical bonds with oxygen that is, it39s tetravalent. aluminum makes three bonds trivalent, calcium makes two divalent and sodium and potassium make one monovalent. so the identity of x depends on how many bonds are needed to make up the total of 16.
