Quick Answer: What Is The Most Reliable Way To Identify A Mineral?

What is the best way to identify a mineral?




One of the best ways to identify a mineral is by examining its crystal form (external shape).



The hardness of a mineral can be measured by its resistance to scratching or abrasion.




Which mineral test is the most reliable?

hardness scaleONE OF THE MOST USEFUL TESTS; the measure of how easily a mineral can be scratched; hardness scale developed by Frederich Mohs -he compares the mineral’s hardness to 10 known minerals; the scale works like this – any mineral that has a greater hardness can scratch a mineral that is softer; hardness is the most reliable …

What is the most reliable physical property to use in identifying minerals?

HardnessHardness. The ability to resist being scratched—or hardness—is one of the most useful properties for identifying minerals.

Which mineral is the hardest?

diamondTalc is the softest and diamond is the hardest. Each mineral can scratch only those below it on the scale.

What are two reasons that color isn’t a good way to identify minerals?

Using color alone to identify a mineral could lead to an inaccurate conclusion. The hardness of the mineral, luster, cleavage, fracture, how it reacts to an acid, and other traits can be used to identify what the mineral is.

What are the color of minerals?

Most minerals, however, are usually white or colorless in a pure state. Many impurities can color these minerals and make their color variable. The property of streak often demonstrates the true or inherent color of a mineral.

How do you identify mineral cleavage?

If part of a crystal breaks due to stress and the broken piece retains a smooth plane or crystal shape, the mineral has cleavage. A mineral that never produces any crystallized fragments when broken off has no cleavage.

What is the least reliable way to identify a mineral?

The color test is the least reliable test because many different minerals have similar colors. A similar test to color is the streak test.

Why is streak more reliable for rock identification?

Streak is the color of a mineral’s powder. Streak is a more reliable property than color because streak does not vary. Minerals that are the same color may have a different colored streak. Many minerals, such as the quartz in the Figure 3, do not have streak.

What mineral shows the true color?

Answer: Streak is the color of the mineral in powdered form. Streak shows the true color of the mineral. In large solid form, trace minerals can change the color appearance of amineral by reflecting the light in a certain way.

Why is the color of a mineral not a reliable method of identification?

Color is the least reliable property for mineral identification. The same mineral can come in a variety of colors and different minerals can be the same color. The color can change over time do to weathering. … Cleavage is a mineral’s tendency to break along flat surfaces.

How easily a mineral can be scratched is called?

hardness is the measure of how easily a mineral can be scratched.
