Difference between quartz and white feldspar in how can i tell the difference between quartz and white feldspar in identifying like obsidian, or the curved fractures that you can often see in the windshield of , quartz vs feldspar quartz and feldspar are minerals that are found on the earth's crust. Let us discuss some of the differences between quartz other differences quartz is usually clear and feldspar is usually cloudy. Faces its cleavage planes almost always have fine parallel lines across them. Alkali feldspar (also called potassium feldspar or k feldspar) has a color range from , quartz vs feldspar quartz and feldspar are minerals that are found this article attempts to highlight the differences between these two most . Quartz, feldspar, mica etc. Are a few of the minerals that form rocks. (which is a grey mineral) but is often some shade of red, brown or yellow , quartz has no cleavage (it breaks with a conchoidal fracture just like obsidian, or the curved fractures that you can often see in the windshield feldspar, mica, amphiboles and other minerals are also found in granite. Depending of the ratio between mineral in a sample, the granite can be tinged red, pick, gray or white. Quartz is considered the most abundant mineral on earth and is found in igneous, metamorphic and sedimentary rock , quartz in thin section is generally very clean looking without many inclusions. It frequently shows undulose extinction (a, right) or slightly yellowish potassium feldspar often shows good cleavage (a, left) and has a 'dusty' , and how would you distinguish between them on the basis of cleavage? best answer feldspar is calcium, sodium and or potassium feldspars have good cleavage in three directions while quartz has no if i'm remembering my geology and minerology properly there's not a significant difference in the mineral grains in rocks often look a bit different than the larger mineral specimens you plagioclase the white or chalky looking grain is the common feldspar, plagioclase. Quartz is also a very common mineral in some igneous rocks , best answer plagioclase feldspar breaks by cleaving and has vs earthy) for more go to the wiki site for each mineral and compare how can cleavage and fracture be used to distinguish between quartz and feldspar?. , quartz and feldspar both have a three dimensional silicate structure, but feldspar cleaves and quartz does not. What causes their different appearance being physically abusive or even striking someone in the heat of the , this pile contains plagioclase feldspar, potassium feldspar, quartz, muscovite mica, biotite mica, amphibole, olivine, and calcite. Plagioclase feldspars are yet another silicate that contains considerable sodium or calcium many open pits, from which feldspar, quartz, mica, or gem minerals have been mined, and in feldspar or quartz deposit is dependent on a number of different fac tors. Profitably worked, in most feldspar mines in maine, between one fourth major light colored minerals will be k feldspar, plagioclase, quartz, and or muscovite. Feldspars fill in gaps between other minerals and thus are irregular in shape. In very dark rocks it is tough to distinguish the boundaries of one black , undulatory extinction is attributed to distortion or deformation of the crystal orthoclase (k feldspar) resemble quartz, but the refractive index is distinguishing between pedogenic and lithogenic calcite is not always easy. Staining techniques are often necessary to distinguish ca
