What property by itself is not a reliable way to identify a mineral?

Color is not a reliable property to identify a mineral because many minerals can occur in a variety of colors due to impurities or variations in their chemical composition. Additionally, different minerals can have similar colors, leading to potential confusion in identification. For accurate mineral identification, it is essential to consider other properties such as hardness, streak, luster, and crystal structure.


Which mineral properties are most useful for identification?

Hardness and streak color are very important. The color of the mineral helps some, as well.


What are subjective and objective mineral properties?

Subjective mineral properties are characteristics that depend on personal perception and interpretation, such as color and luster, which can vary based on individual observation. In contrast, objective mineral properties are measurable and consistent, regardless of who observes them; examples include hardness (measured by the Mohs scale), specific gravity, and crystal structure. While subjective properties can influence identification, objective properties provide definitive criteria for classifying and studying minerals.


What is the most diagnostic physical property of a mineral?

The most diagnostic physical property of a mineral is its hardness, which is measured on the Mohs scale. Hardness indicates how resistant a mineral is to scratching and can help distinguish between different minerals. For example, talc is the softest mineral on the scale (1), while diamond is the hardest (10). Other important properties include color, luster, and streak, but hardness is often the most reliable for identification.


Is the cleavage for a mineral is always the same for that mineral?

Yes, all different samples of that mineral will have the same cleavage.

Compare and contrast the different simple tests for mineral identification presented in the lesson?

There are several different tests that can help identify minerals. You can use any of them to determine the sample.


Why are the other mineral properties less useful for identification?

Other mineral properties such as luster, streak, and specific gravity are less useful for identification because they can vary widely among different minerals and may not be unique to a specific mineral. In contrast, properties like hardness and cleavage are more consistent and can help accurately identify a mineral.


What is the least reliable physical property for mineral identification?

Color is the least reliable physical property for mineral identification because many minerals can have the same color but different properties.


What type is Sample B on Mineral Identification on Gizmo's?

Sample B on the Mineral Identification Gizmo is calcite.


What information can be obtained from a mineral identification chart?

A mineral identification chart provides information about the physical properties of minerals, such as color, hardness, luster, and cleavage. By using the chart, one can identify and classify different minerals based on these characteristics.


What is the powdered form of the mineral?

The powder indicates the true color of the mineral and is an aid in mineral identification. That can also be called a streak.


What physical property is is unreliable as an identification clue for minerals?

Color is unreliable as an identification clue for minerals because different minerals can have the same color and the same mineral can exhibit different colors due to impurities.


What information can be obtained from a geology mineral identification chart?

A geology mineral identification chart provides information about the physical properties of minerals, such as color, hardness, luster, and crystal structure. By using the chart, one can identify and classify different minerals based on these characteristics.


Why is the color of a mineral not a reliable?

The color of a mineral is not a reliable identification factor because it can vary due to impurities or environmental factors. Different minerals can have the same color, making it difficult to distinguish them based on color alone. It is more reliable to rely on other properties like hardness, luster, cleavage, and specific gravity for mineral identification.


Why is streak more reliable for rock identification?

Streak is more reliable for rock identification because it reflects the true color of the mineral present in the rock. Minerals have a consistent streak color, which can help differentiate between similar-looking rocks. In contrast, the color of the rock itself can be influenced by impurities or weathering, making it less reliable for identification.


Is color the best physical characteristic for mineral identification?

Specimen color is the least reliable method of mineral identification. Better characteristics are streak, density, and crystal structure.


How reliable is color when determining what a mineral is?

Color is the least reliable of a mineral's characteristics used in its identification.
