It often does not match the observable color of the specimen. Differences between streak and observable color can be due to inclusions, staining, refraction, impurities, or exposure to heat and radiation.

∙ 13y agoA mineral can exhibit multiple colors. Take quartz, for example; amethyst/purple, carnelian/red, citrine/yellow. Although specimens of a specific mineral may appear to be different colors, their streak (the color of the powdered mineral) will be the same color. In the above case, all the types of quartz mentioned have a white streak.

Well minerals is in earth inorganic solid material found in nature that always has the same chemical makeup atoms arranged in an orderly pattern and properties such as cleavage and fracture color hardness and streak and luster.

Pyrite
Can most minerals be identified by color alone?
no, because many of the same minerals have the same color
Why is color least useful in the id of minerals?
Because many of the minerals share the same color.
What are the properties used to identify minerals?
luster streak shape density color (not always reliable tho mulltiple types of minerals can have the same color) odor tenacity reaction to acid cleavage magnetism electrical properties
Why is color not a reliable physical characteristics when indentify a mineral?
Two different minerals can be the same color or two of the same minerals can be different colors.
Why is color often an unreliable property in identifying minerals?
because many minerals are the same color, and some minerals come in many colors

What is the problem with using only color to identify a mineral Give an example of a mineral that demonstrates your answer?
The color of many minerals is highly variable. Many minerals are found in many different colors. Eg. while malachite is always green, and sulfur always yellow, quartz can come in shades of purple, green, blue, red, yellow, brown, pink, etc., and tourmaline, garnet, calcite, and fluorite are equally color variable.
Why is color not always a good way to identify minerals?
Color is not always a good way to identify minerals because some minerals change colors at certain temperatures. Some minerals have several colors and some are found in varied colors.
Why is color not a good mineral property to use to identify minerals?
Simply because colour has nothing to do with any other property of the substance in question.
Why chemical properties not always used to identify minerals?
The stripe, and color
Why is using a minerals streak more reliable then using color to Identify a mineral?
Some minerals can be the same color but have different streaks.
