What would not help you identify a mineral?
tendency to float
Students want to identify a rock in a nearby field. Which of the following properties would be most useful in identifying the unknown rock?
Mineral content
What are two pieces of criteria for identifying a mineral?
Two distinguishing characteristics of a mineral are its crystalline structure and its hardness. Other field tests would include a streak test and possibly a test of specific gravity. Color can also be of some use.
Give three reasons why it is difficult to identify a mineral by its color alone?
A mineral's color may be influenced by inclusions of other elements or minerals, or even exposure to heat, light, and radiation. A more reliable identification based on color would be the streak, or color of the powdered mineral.
Why did geologists come up with so many ways to identify mineral?
Being able to identify minerals is like being able to identify diamonds from quartz--The person that makes the right choice is rewarded financially. Correct information is the kingpin of mining.
How do you find the mineral in a rock?
In some rock, it is not possible to visually detect a mineral. Tests must be done to identify the minerals which compose the rock. Such tests would include: reaction to acids, specific gravity, texture, and color.
Are some tests better than others for identifying certain minerals?
Yes, you can usually identify the mineral salt by its taste. However, with most minerals one would apply a series of tests, eg hardness, flame test, colour, density, streak, shape in order to identify the mineral.
What would not help you identify a mineral?
tendency to float
What would you use the Mohs scale of hardness for?
to identify a mineral
What would you use the Mohs scale for hardness for?
to identify a mineral
Which information would probably be most helpful to someone trying to identify a mineral sample?
Many igneous rocks can be identified by the position of their minerals.
Why can't color alone be used identify most minerals?
Many minerals have similar color, and mineral color can be altered by trace amounts of impurities or by weathering. A better indicator would be the mineral's streak, which is the color of the mineral when powdered, although this characteristic can't be used alone in mineral identification.
Students want to identify a rock in a nearby field. Which of the following properties would be most useful in identifying the unknown rock?
Mineral content
What is the least destructive mining method?
The least destructive method would be to simply identify the desired mineral specimen by eye and pick it up.
What two tests would you use to identify talc?
I suppose the the visual inspection and the measurement of hardness are sufficient. A magnesium test may be useful.
When would an overflow error occur?
Most likely during an unkown "command" overflow
Why is this mineral economically important?
To help the economy? Sort of I mean it would be hard to make soda cans without aluminum so yes it does benefit the economy, and it also benefits our lives
