Examples of mineral characteristics:
- density
- hardness
- refractive index
- chemical composition
- magnetic properties
- cleavage
- crystal system
- radioactivity
The color of a mineral is the least useful when identifying minerals. A mineral can exist in various colors. This is because presence of certain chemicals will change the color of the mineral. Weathering can also change the color of the mineral. Therefore color is not a good property to identify minerals.
Luster is the way a mineral reflects in the light. Streak is the color of a mineral in powdered form.
hardness streak and luster and color
A streak test is used to determine a minerals streak color. This can help in with the identification of minerals. A streak test is performed by rubbing the mineral on an unglazed ceraminc tile, then observing the color of the streak which is left behind. All minerals do not leave streaks. Harder minerals will not streak, but this can also be used as a tool for identifying the mineral, if you are familiar with the hardness scale.
There are 7 types of properties.1. luster2. streak3. cleavage4. fracture5. hardness6. density7. specific gravity
i asked my teacher and he said just to put metallic or shiny to describe the color. the luster is metallic according to my book.
The color, luster, and crystal shape of a mineral may be observed just by looking at the mineral. Some minerals have very distinctive colors that help identify them. Although the color of a mineral can give away its identity, color is the least useful property for mineral identification.
Streak test because minerals can vary in color, size and shape but their streak color will always be the same for that specific mineral. Calcite comes in many shapes and colors, but its streak is always white.
the color and streak or luster
By the mineral color, streak color, luster, hardness, the property of the mineral, if it's fracture or cleavage and it's specific gravity. Those are just basic, so there's many other ways to ID a mineral.
Minerals vary in ways they can be distinduished. Some are easy to identify by hardness, color , streak, or luster
Minerals have certain properties, or characteristics, that help to identify them. Minerals can be identified by their color, luster, streak, cleavage, hardness, specific gravity, and even by their chemical composition.
color streak and luster
Properties used to identify minerals.
Hardness, Cleavage, Luster, Color, Streak, and Texture.
Color can change in a mineral when in certain temperatures
because the color of a mineral can be the same as some other minerals but all minerals have a different property between them
