Why are other mineral properties less useful for identification?
GeologyWhy are other mineral properties less useful for identification? Because the properties can vary with different minerals. They can be deceiving.
What are the classification of mineral?
In this system, minerals are classified into eight main mineral groups based on chemical composition. These classes are: native elements, silicates, oxides, sulfides, sulfates, halides, carbonates, phosphates, and mineraloids.
What are the 5 classifications of a mineral?
The broadest divisions of the classification used in the present discussion are (1) native elements, (2) sulfides, (3) sulfosalts, (4) oxides and hydroxides, (5) halides, (6) carbonates, (7) nitrates, (8) borates, (9) sulfates, (10) phosphates, and (11) silicates.
What are minerals and their properties?
Minerals can be identified by their color, luster, streak, cleavage, hardness, and even by their chemical composition. Using these properties is one way a Geologist defines and identifies what kind of mineral a specimen is. The museum has 6 wall spaces at the museum dedicated to these specific properties with examples.
What are the 7 mineral properties?
Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
What are the 10 mineral properties?
These include: color, streak, hardness, luster, diaphaneity, specific gravity, cleavage, fracture, magnetism, solubility, and many more. These physical properties are useful for identifying minerals.
What are the 3 classification of rocks?
There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water.
What are the minerals?
A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.

- The igneous form of rocks does not include any fossil deposits. …
- Most igneous forms include more than one mineral deposit.
- They can be either glassy or coarse.
- These usually do not react with acids.
- The mineral deposits are available in the form of patches with different sizes.
- Sedimentary Rocks. Sedimentary rocks are formed from pieces of other existing rock or organic material. …
- Metamorphic Rocks. Metamorphic rocks are rocks that have been changed from their original form by immense heat or pressure. …
- Igneous Rocks.
How are rocks and minerals classified?
CLASSIFICATION The classification of rocks is based on two criteria, TEXTURE and COMPOSITION. The texture has to do with the sizes and shapes of mineral grains and other constituents in a rock, and how these sizes and shapes relate to each other. Such factors are controlled by the process which formed the rock.
What are the two classifications of minerals?
There are two kinds of minerals: macrominerals and trace minerals. You need larger amounts of macrominerals. They include calcium, phosphorus, magnesium, sodium, potassium, chloride and sulfur.
What is rock and its classification?
Rocks are classified according to characteristics such as mineral and chemical composition, permeability, texture of the constituent particles, and particle size. These physical properties are the result of the processes that formed the rocks.
What are the classifications of different rocks and its characteristics?
These classes are (1) igneous rocks, which have solidified from molten material called magma; (2) sedimentary rocks, those consisting of fragments derived from preexisting rocks or of materials precipitated from solutions; and (3) metamorphic rocks, which have been derived from either igneous or sedimentary rocks under …
What are the properties of rock?
Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level. Color and density are determined primarily by the chemical composition.
