What would best to identify a sample of lazurite?
The most suitable method to identify a sample of lazurite would be X-ray diffraction analysis, which can determine the crystal structure and identify the mineral based on its unique patterns. Additionally, spectroscopic techniques such as Raman spectroscopy or infrared spectroscopy can be used to analyze the chemical composition and molecular structure of the sample.
How can density help identify a mineral?
Each mineral has a characteristic density (or range of densities), so if the measured density is a close match to a mineral you know, it MAY be that mineral; if it doesn't match, it is something different.
What technique do you use in the laboratory to determine the ions present in a mineral sample?
One technique commonly used to determine the ions present in a mineral sample is X-ray fluorescence spectroscopy (XRF). In XRF analysis, the sample is bombarded with X-rays, causing it to emit fluorescent X-rays characteristic of the elements present. The emitted X-rays are then detected and used to identify and quantify the different elements and ions in the sample.
What arrangement of atoms in a repeating pattern in a mineral causes the formation of?
The arrangement of atoms in a mineral sample can cause the formation of crystals.
Why may a geologist have to break a mineral sample to determine its true color?
Rocks are exposed to the elements and undergo weathering. This can cause the minerals that they are composed of and that are exposed at the surface to become discoloured which can make them hard to identify. A geologist will often use a geological hammer to crack the rock sample to see the fresh, unweathered minerals.
How might you identify whether sample might be lodestone?
One way to identify a potential lodestone sample is by using a compass needle. Lodestones are natural magnets and will attract a compass needle, causing it to align in the magnetic north-south direction. Additionally, lodestones are usually black or brown in color and often have a metallic luster. Conducting a magnetism test or using a magnet to see if the sample is attracted to it can also help determine if it is a lodestone.
Can you use a dichotomous key to identify a specific mineral sample?
Yes, a dichotomous key can be used to identify a specific mineral sample by asking a series of questions about its physical characteristics, such as color, luster, hardness, and streak. By following the key's set of paired choices based on these characteristics, you can narrow down the options and eventually identify the 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.
What tool do you measure minerals?
A tool commonly used to measure minerals is a refractometer. This instrument determines the refractive index of a mineral sample, which can help identify the type of mineral based on how light is bent as it passes through the sample.
A scientist suspect that a mineral sample is a carbonate. which useful for identifying the sample as a carbonate?
To identify the mineral sample as a carbonate, the scientist can perform an acid test. If the sample fizzes or produces bubbles when acid is added, it indicates the presence of carbonate minerals. Additionally, spectroscopic analysis can be used to detect the specific chemical composition of the mineral, confirming its classification as a carbonate.

What is the density of a mineral sample?
The density of a mineral sample is a measure of its mass per unit volume. It can be calculated by dividing the mass of the sample by its volume. The density of a mineral sample is a characteristic property that can help in identifying the mineral.
Why are chemical properties not always used to identify minerals?
Testing the chemical properties of a mineral might damage the mineral sample. Also, these tests can be complex and may require expensive equipment.
How do you get the specific gravity of a mineral?
Fill a beaker with water, and weigh it. Weigh a sample of the mineral. That's the mass of the mineral. Put the sample in the beaker and weigh that. The weight of the water-filled beaker plus the weight of the mineral sample will be greater than the weight of the beaker with mineral sample and water. The difference is the weight of the displaced water, in grams. The volume of the mineral sample, in cubic centimeters is equal to the weight of the displaced water, in grams. Calculate the specific gravity of the mineral by dividing the weight of the mineral sample by the volume of the mineral sample. Example: your beaker weighs 40 grams. Filled with water, it's 1040 grams. The sample of mineral weighs 160 grams. The beaker with the sample of mineral and water weighs 1179.7 grams. The mineral, and the beaker with water would have a combined weight of 1200 grams, but the beaker with mineral and water weighs 20.3 grams less than that, so the mineral sample is displacing 20.3 cubic centimeters of water. Given a mass of 160 grams and a volume of 2.03 CC, the specific gravity would be found by dividing 160 by 20.3. It's 7.85. (Which happens to be the specific gravity of some iron.)
What type is Sample B on Mineral Identification on Gizmo's?
Sample B on the Mineral Identification Gizmo is calcite.
How can density help identify a mineral?
