The definition is based on strength and durability.Minerals are naturally occurring inorganic substances of more or less definite chemical composition,displaying more or less definite physical properties.As the basic constituent of rock,minerals control much of rock behavior.People also askWhat are the physical properties of minerals?What are the physical properties of minerals?The physical properties of minerals are related to their chemical composition and bonding.Some characteristics,such as a minerals hardness,are more useful for mineral identification.Color is readily observable and certainly obvious,but it is usually less reliable than other physical properties.How are Minerals Identified? Figure 1.Reading Physical Characteristics of Minerals GeologyOutcome Identifying Minerals GeologyIdentify and classify common rock forming minerals.The solid earth is made of rocks,which are made of minerals.To understand rocks you need to become familiar with minerals and how they are identified.This outcome gives you the background needed to understand the terms used in identifying minerals.This section will introduce you to minerals.
You will learn the various techniques used by geologists to identify and classify minerals.What Youll Learn to Do.Identify minerals based on their physical characteristics.Sort minerals into the correct mineral class.Learning Activities.The learning activities for this section include the following Reading Physical Characteristics of Optical Properties of Minerals Geology ScienceMinerals and propogation of light Opaque minerals minerals in which light does not go through ReadingPhysical Characteristics of Minerals Geology#224; always black even in thin sections.Typically these have molecules with higher atomic density (which includes many ore minerals).How light reflects off of these minerals isMinerals Optical and Physical Properties Rocks Geology Colour The colour of any object is a light dependent property- it is the appearance of the particularLustre Simply defined,it is the shine of a mineral.Technically speaking,it is intensity of reflectionStreak It is an important and diagnostic property of many coloured minerals.Simply defined,Hardness It is a fairly constant and diagnostic property of minerals.Hardness may be defined asCleavage It is defined as the tendency of a crystallized mineral to break along certain definiteFracture The appearance of the broken surface of a mineral in a direction other than that ofTenacity The behaviour of a mineral towards the forces that tend to break,bend,cut or crush it isStructure (Form) Minerals often occur in characteristic body forms or physical shapes.TheSpecific Gravity The density of a substance is a fundamental property of great significance and isForm It is the internal atomic arrangement of a mineral which is manifested outwardly byMinerals Optical and Physical Properties Rocks GeologyMinerals often occur in characteristic body forms or physical shapes.The physical make up of a mineral is expressed by the term structure and is often helpful in identifying a particular mineral.In reality,structure merely shows the habit in which the crystal or crystalline substance making a mineral tends to

Minerals with metallic luster can also be described as having a shiny,dull,or iridescent luster.For example,the pyrite mineral shown in the left photo has mostly a shiny,metallic luster.Minerals of metallic luster are opaque to light,even on thin edges.Metamorphic Rock Definition ,Properties and FormationAll rocks are composed of minerals,and each mineral is simplest solid over a specific range of temperatures and pressures.Outwith that range it will generally tend to break down or combine with a neighbouring mineral to shape a brand new mineral.The system of metamorphism is associated with the formation of particular metamorphic minerals.Luster The light-reflecting qualities of a mineral.- GeologyEleven adjectives are commonly used to describe mineral luster.They are metallic,submetallic,nonmetallic,vitreous,dull,greasy,pearly,resinous,silky,waxy,and adamantine.These adjectives convey - in a single word - a property that can be important in the identification of a mineral.
Since minerals are the building blocks of rocks,it is important that you learn to identify the most common varieties.Minerals can be distinguished using various physical and/or chemical characteristics,but,since chemistry cannot be determined readily in the field,geologists use the physical properties of minerals to identify them.Glad You Asked How Do Geologists Identify Minerals Color.Some minerals can be recognized by their color azurite is always a deep blue and malachiteStreak.A streak test is accomplished by rubbing the mineral on a porcelain plate,also known as aHardness.Hardness is a measure of a minerals resistance to abrasion.A numerical value forCleavage.Cleavage can be observed in minerals that tend to break along one or more flat surfacesSpecific Gravity.Specific gravity is the relative weight of the mineral to an equal volume of water.Crystal Form Mineral Habit.Crystal form is responsible for the minerals geometric shape andOther Physical Properties.Does the mineral have a taste (for example,salt)?
