answ2. Simple visual inspection is always the first method.
For a tiny sample, a few mg of pure material, x-ray diffraction XRD.
If a small sample, (<1gm) x-ray fluorescence XRF in an electron microscope.
A larger sample <100 gm) x-ray fluorescence using a powder sample.
The above methods assume easy access to the equipments.
Thin section microscopy is a simple technique, but takes some time in sample preparation.
The determination would start with the visual inspection of the hand sample.
You will know what the origin of the rock is, and that gives clues to the cohort of minerals expected.
This would be followed by grinding the rock to sort out the particular minerals you are interested in.
What else can I help you with?
Is salt water a mineral?
No. a mineral is a compound of fixed chemical composition and of fixed crystal structure.
Is coprolite a mineral?
Coprolite is a valuable trace fossil for the archaeologist, but is NOT a mineral.A mineral must be of fixed composition, and have a fixed crystal shape.
A minerals hardness with respect to other minerals can be determined by?
scratching the mineral acrros a glass plate
How can minerals be identifed by their physical properties?
Yes
Which of these would be most likely to determine whether or not the deposit would be mined?
whether the cost of mining will be less than the value of the mineral
What do geologists use the acid test for?
Geologists use the acid test to identify and distinguish between different types of minerals based on their reaction to acid. By observing if a mineral fizzes or dissolves when exposed to acid, geologists can determine the mineral's chemical composition.
Which of the following would be studied by a geologist A The composistion of a mineral B The climate of a particular area C The tides of the ocean D The methods used to protect the environment?
geology= study of rocks,minerals and earth. the answer to your question is A. the composition of a mineral.
How do geologists test rocks?
Geologists test rocks by conducting various analytical techniques such as petrographic analysis, X-ray diffraction, and chemical analysis. These methods help geologists determine the mineral composition, structure, and other important characteristics of rocks. Additionally, geologists may also perform field observations and measurements to gather more information about the rocks.
How do geologists learn how a rock formed?
Geologists study the rock's mineral composition, texture, and structure to determine how it formed. They also consider the rock's surroundings and the geological processes that may have been involved in its formation, such as volcanic activity or sedimentary deposition. By analyzing these factors, geologists can piece together the rock's history and understand how it was created.
What do geologists observe when studying a rock sample?
Geologists observe the color, texture, mineral composition, and structure of a rock sample to determine its formation process, age, and geological history. They may also conduct tests to analyze the chemical composition and physical properties of the rock.
What do geologists base the classification of rock on?
Geologists classify rocks based on their mineral composition, texture, and formation process. These characteristics help geologists understand the origin and history of the rocks, as well as their physical and chemical properties.
What test do geologists use to determine the hardness of a mineral?
Geologists use the Mohs scale of mineral hardness to determine the relative hardness of a mineral by scratching it with minerals of known hardness. The scale ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals.
When geologists say that a mineral always contains certain elements in definite proportions they mean that the mineral always has what?
When geologists say that a mineral always contains certain elements in definite proportions, they mean that the mineral always has a specific chemical composition. This composition is a key characteristic that helps identify and classify minerals. Minerals are composed of specific elements arranged in a precise crystal lattice structure.
How did geologists determine the divisions of the geologic time scale?
Mainly abrupt changes in mineral layers or the fossils in them.
Why do geologists use microscopes?
Geologists use microscopes to study the mineral composition and texture of rock samples at a microscopic level. This helps them identify minerals, determine the formation history of rocks, and make interpretations about geological processes. Microscopes allow geologists to observe features that are not visible to the naked eye, aiding in their research and analysis.
Name three ways geologists study a rock sample?
Geologists study rock samples by analyzing their mineral composition under a microscope, conducting chemical tests to determine their elemental composition, and measuring their physical properties such as density and hardness. They may also use techniques like X-ray diffraction and spectroscopy to further study the rock's structure and properties.
What types of geologists are there?
There are different types of geologists that study oil exploration, mineral exploration and mineral mining. There are also engineering geologists.
