The universal scale used to test the hardness of a mineral or rock is known as Moh's scale It was devised by the Austrian mineralogist Frederick Moh in the early 's as a crude but practical method of comparing scratch resistanceRock gypsum is common in Kansas It occurs as thick beds, or layers, of sedimentary rock and is mined in the Red Hills of south-central Kansas and in , Hardness: 2 .MOH'S RELATIVE SCALE OF HARDNESS , 2 Gypsum This mineral can , and is an essential component of crystalline rocks such as granite, gabbro.
Gypsum Click on image for full size , You can find gypsum in sedimentary rocks, deserts, , Hardness: 2 on Mohs Hardness Scale;The Mohs scale of mineral hardness is based on the ability of one natural sample of mineral to scratch another mineral visibly The samples of matter used by Mohs are all different minerals Minerals are chemically pure solids found in nature Rocks are made up of one or more minerals As the hardest known naturally occurring substance when ,Home Animals Fossils Insects Minerals Rocks Funstuff Hardness Some minerals are harder than others The hardness of a mineral is a good tool you can use to help identify minerals In , a man named Fredrich Mohs invented a scale of hardness called Mohs Scale which is still used today He selected ten standard minerals, and arranged them in order of increasing hardness.

Gypsum, also called hydrated calcium sulphate (CaSO4 Â 2H2O) and anhydrite (CaSO4), also called hydrous calcium sulphate are the major minerals in the sedimentary rocks of rock gypsum and rock anhydrite respectively Gypsum consists of calcium, sulfur and water while anhydrite consists of calcium .Estimation of rock engineering properties using hardness , effect of rock hardness on rock , compressive strength and Young's modulus in gypsum from .Introduction Properties Common rock-forming minerals Economic minerals Gypsum , Hardness - 2 Specific.
(2) hardness (4) angles of cleavage The diagram below represents geological processes that act continuously on Earth to form different rockHow to conduct a hardness test on an unknown rock or mineral using Mohs Scale of hardnessTalc (1), the softest mineral on the Mohs scale has a hardness greater than gypsum (2) in the direction that is perpendicular to the cleavage Diamonds (10) also show a variation in hardness (the octahedral faces are harder than the cube faces) For further information see articles from the American Mineralogist on microhardness, the Knoop tester, and diamonds Mohs' hardness.
All varieties of gypsum are very soft minerals (hardness: 2 on Mohs Scale) This is the most important identifying characteristic of gypsum, as any variety of gypsum can be easily scratched with a fingernail Also, because gypsum has natural thermal insulating properties, all varieties feel cold to the touch Varieti Though sometimes grouped ,Mica is a mineral name given to a group of minerals that are physically and chemically similar They are all silicate minerals, known as sheet silicates because they form in distinct layers Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible Mica is heat-resistant and doesRocks and Minerals Multiple Choice , a foliated metamorphic rock The table below shows the hardness of four common , Most rock gypsum is formed by the (1).
