- Color is important in mineral identification, but it can be a complicated subject. Experts use color all the time because they have learned the usual colors and the usual exceptions for common minerals. If you're a beginner, pay close attention to color but do not rely on it.

- A mineral species has to possess these five characteristics... Minerals are solid, naturally occurring, inorganic compounds that possess an orderly internal structure and a regular chemical composition. A mineral species has to possess these five characteristics to be regarded as scientifically valid. The first and most basic characteristic of all minerals is that they occur naturally.

High School Earth Science/Identification of Minerals 1 You can identify a mineral by its appearance and other properties. 2  The color and luster describe the appearance of a mineral, and streak describes the color of the powdered mineral. 3  A mineral has a characteristic density. 4  Mohs hardness scale is used to compare the hardness of minerals.he scale lists common minerals in order of their relative hardness. You can use the minerals in the scale to test the hardness of an unknown mineral. As you can see, diamond is a 10 on Mohs Scale. Diamond is the hardest mineral, which means that no other mineral can scratch a diamond.

Mineral Minerals can be described by various physical properties which relate to their chemical structure and composition. Common distinguishing characteristics include crystal structure and habit, hardness, lustre, diaphaneity, colour, streak, tenacity, cleavage, fracture, parting, and specific gravity.More specific tests for minerals include magnetism, taste or smell, radioactivity and reaction to acid.ommon distinguishing characteristics include crystal structure and habit, hardness, lustre, diaphaneity, colour, streak, tenacity, cleavage, fracture, parting, and specific gravity.

- Minerals are defined as naturally occurring, inorganic, solids with a definite chemical composition and a regular, internal crystalline structure. The keys to this definition are the chemical composition and the crystalline structure. Different chemical compositions result in different minerals. A good example is the mineral plagioclase.

Minerals The physical characteristics of minerals include traits which are used to identify and describe mineral species. These traits include Shape, Color, Streak, Luster, Density, Hardness, Cleavage, Fracture, Tenacity, and Crystal Habit.inerals can be very beautiful colors. Same type of mineral may be found in a variety of colors. For instance, the minerals quartz can be found in many colors including pink, purple, white or black.

WHAT IS THE DIFFERENCE BETWEEN A ROCK AND WHAT IS A MINERAL All minerals belong to a chemical group, which represents their affiliation with certain elements or compounds. The classified chemical groups are known as: Elements, Sulfides, Oxides, Halides, Carbonates, Nitrates, Borates, Sulfates, Chromates, Phosphates, Arsenates, Vanadates, Tungstates, Molybdates, and Silicates.nother unique category of minerals is the organic minerals. While this term is technically an oxymoron, since the definition of a mineral requires it to be inorganic, there are several naturally occuring rare organic substances with a definitive chemical formula. The best known example of this is Whewellite.

An overview of peat in Florida and related issues ( FGS: Special publication 27 ) Defining a mineral. A mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement. This may seem a bit of a mouthful, but if you break it down it becomes simpler. Minerals are naturally occurring. They are not made by humans. Minerals are inorganic.

The Basics of Rocks and Minerals and Polar Geology There are four criteria that must be met in order for something to be called a mineral: 1  Not formed from the remains of plants or animals; that is, inorganic. 2  Naturally occurring, not man-made. 3  Has the same chemical makeup wherever it is found (Ex: Quartz is always SiO2)

- Color, luster, streak, hardness, cleavage, fracture, and crystal form are the most. useful physical properties for identifying most minerals. Other properties-such as. reaction with acid, magnetism, specific gravity, tenacity, taste, odor, feel, and. presence of striations-are helpful in identifying certain minerals.

Mineral Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species, which were determined by the mineral's geological environment when formed.

- 1 A mineral is an element or chemical compound that is normally crystalline and that has been formed as a result of geological processes (Nickel, E. H., 1995).  2 Minerals are naturally-occurring inorganic substances with a definite and predictable chemical composition and physical properties.. ( 3 O' Donoghue, 1990).

WHO RULES THE WORLD ? Geology 2 Lab 2 Igneous Rock Identification. Goal: To identify the most important types of igneous rocks. You will be responsible for. the 9 rock names given in bold below. This lab will work just like the previous mineral. lab. First you will look at a series of examples of all the rock types. Then you will get a. suite of unknown minerals for you to identify. Like most rock types, the names of igneous rocks are based on their textures and. the minerals they contain. The texture results from cooling history whereas the. mineralogy depends on the chemical composition of the rock.

Mineral Groups Mineral Groups. One of the first steps in studying a group, such as minerals, is to subdivide them according to similarities they may have with one another. This is called classification. Minerals are classified according to chemical composition. There are seven major chemical groups. There are also several minor groups. These include: the sulfosalts, nitrates, borates, tungstates and molybdates, and the phosphates, arsenates, and vanadates.
