Chemically, these rocks are 60-70 percent silica (or silicon dioxide) and 10-15 percent aluminum oxide (Al 2 O 3 ), with significant amounts of potassium (K), sodium (Na), and other elements. The difference between geodes and feldspar. Quartz breaks in curvy and irregular shapes ( conchoidal fracture ). The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. The key difference between quartz and feldspar is that the major chemical element present in quartz is silicon whereas, in feldspar, it is aluminum. The most common of these is a mixture of quartz, potash feldspar, and granitic rock fragments. The feldspars are all aluminum silicates of the alkali metals sodium, potassium, calcium and barium. 1. K-feldspar, Quartz and Biotite in a Granite. Quartz. Explain Since both quartz and feldspar are considered hard and would scratch glass after a hardness test, you can tell the difference by the mineral's cleavage. when comparing the two, feldspar is more commonly found than quartz. Finally, Quartz is usually transparent or translucent, while feldspar is typically opaque. Feldspar grows (when allowed to) into rectangular crystals, and then usually breaks the same way. As you turn a piece of rock in the light, quartz glitters and feldspar flashes. This breakage pattern is called cleavage, and feldspar has two directions of cleavage that meet at close to a 90 degree angle (just like a stairway). When the ratio between aluminum and silicon is in the same proportion, the feldspar is classified as feldspar, when there is a higher percentage of silicon in the ratio, the mineral maintains the classification of feldspar. Feldspar is more commonly found than quartz. A mineral is a crystalline object that has the same chemical makeup in all its parts. Other differences: quartz is usually clear and feldspar is usually cloudy.

This view shows two large flakes of brownish green biotite and minor hornblende (darker smaller grains) near the left edge; the hornblende does not have a distinctive appearance. Feldspar forms when magma solidifies into igneous rocks. Answer (1 of 2): It comes down to the source of the sand grains, and to a variable degree, climate and time. Feldspar, however, breaks readily along flat faces, a property called cleavage. Feldspars are a group of rock-forming aluminium tectosilicate minerals, containing sodium, calcium, potassium or barium. The most significant difference to note between these two minerals is that feldspar is a group of minerals, not just one individual mineral, while quartz is one specific mineral that has many variations. A basic quartz counter begins at about $60 per square foot. Granite Noun. The biotite has a pebbly texture and micaceous cleavage.The right half of the view contains a large grain of clear to cloudy K-feldspar. Hardness. So, if the mineral has cleavage and sparkles, it may be feldspar. Common colors are gray, white, pink, and yellow-brown. What rock has feldspar and quartz? Feldspar has been derived from 'Feld' (meaning field) and Spath (meaning rock which does not contain ore). Colors: Clear, white, grey, black, pink, amber, brown, purple.
