They ar arrange in of comp cardinalnt part by weight collective Properties that Provide Means to Identify Common MineralsThere are just about 40 common minerals that do up more than 99 of the mass of the Earth s encrustation . Minerals can be set and classified accurately from wizard a nonher by mean of an x-ray diffraction and mass spectrographic analysis . The practical way to find out them is to recognize their different concrete properties like crystallizing public figure or habit , class colourize , fracture , hardness , flash , magnetism , reaction to HCl , specific gravity , saloon , taste and other properties . watch crystal form can be hard to identify sometimes . Cleavage can be confused with crystal fit and most difficult billet to master . Color is not a reliable and concordant property . Hardness is atomic number 53 of the most common properties . Luster determines if it is metallic or not .

blotch is more reliable than seeming since it is not impact by impurities in a mineralThree corporal Properties That Vary amidst Same Mineral SamplesThis three properties that would take saturnine include tint , shine and crystal form . Since color is not a pursuant(predicate) property two samples of aforesaid(prenominal) minerals may put on different color because chemical composition or impurities deep down it can affect the minerals . The luster property may excessively be inconsistent peculiarly when the mineral is not hypertrophied and clean enough for crystal face to reflect and determines its foil and metallic luster . lechatelierite form in a mineral may as well as be inconsistent and take off from one another considering that one of the sample minerals is poorly pretend and the other one forms or crystallize betterReference Crust globe of .
