During this lab activity students will use their knowledge of the physical properties of minerals to investigate and describe seven common minerals including quartz, feldspar, biotite mica, calcite, pyrite, graphite, and talc. Students will determine hardness, color, luster, streak color, and cleavage using various handson testing methods.
The physical properties of a mineral depend on the kind of atoms it is composed of and, more critically, the way these atoms fit together to form the mineral''s crystal structure. Near the top of this case on the left, you will notice two models showing the atoms in the crystal structures of two minerals with actual specimens displayed above them.

The chemical properties of minerals mainly reflect the chemical properties of the atoms present in each. However, even here these properties depend on the way the atoms are bound in the mineral''s crystal structure. Let us examine the property known as solubility — the ability of a mineral to dissolve in a liquid, like salt and water.
Physical Properties of Minerals. Physical Property: Description: Materials Used For Testing: Mohs'' Hardness: Hardness measures the resistance of a mineral to being scratched. The Mohs'' Hardness Scale ranges from 1 to 10. Objects of equal hardness can also produce a scratch with greater effort (like grinding a diamond with diamond dust
Many minerals have different colors and some minerals'' colors are identical to other minerals'' colors. It is important to understand what causes color in minerals in order to understand this mineral property. Color in minerals is caused by the absorption, or lack of absorption, of various wavelengths of light.
Mineral Properties. We use minerals in our everyday lives. Most of us are well aware of common uses of minerals, such as copper in electric wiring, gold and silver in jewelry, and even salt or
Physical properties of minerals. Basic rock types. The rock cycle. Minerals . Natural . Solid. Atoms arranged in orderly repeating 3D array: crystalline. Not part of the . tissue. of an organism. Composition fixed or varies within defined limits. Minerals are the "building blocks" of rock.
Each mineral has a specific chemical composition and is different from the other minerals by some physical properties. Chemical properties: chemical composition, solubility in water or acids
Physical Properties of Minerals. 7 physical properties of minerals. STUDY. PLAY. Hardness. ability of a mineral to resist scratching. color. one way to identify a mineralcolor alone is not a reliable clue. crystal shape. a mineral crystal forms in one of 6 basic shapes:
Minerals embody numerous physical properties, which make them much more interesting and complex than commonly perceived. Several of these properties are essential in mineral identifiion. With enough experience, a mineral can often be accurately identified by simply viewing it.
THE CHEMICAL PROPERTIES OF MINERALS. Atoms, Molecules, and Elements. Every substance on earth is made of atoms, the building blocks of all matter. There are all different types of atoms, and each type of atom is classified as an element.Atoms will bond together to form molecules, which are organized agglomerations of different types of atoms.. There are ninety two elements that occur naturally
Geology Laboratory: Mineral Properties Revised on 8/27/2012 Page 2 of 13 The precise chemical composition and internal atomic that defines estructure ach mineral also directly determines its outward appearance and physical properties. Thus, in most cases, general appearance and a few physical easily determined
PHYSICAL PROPERTIES OF MINERALS: Influenced largely by chemical composition and atomic structure of the mineral. I. Color and Some Related Properties of Minerals Minerals are colored because certain wavelengths of light are absorbed, and the mineral color
Mineral Identifiion • Since we can''t all have xray diffraction machines and electron microscopes, we identify minerals by visual and chemical properties called physical properties. • Types of physical properties that geologists use include:
3.2 PHYSICAL AND CHEMICAL PROPERTIES Information regarding the physical and chemical properties of used mineralbased crankcase oil is loed in Table 32.
Physical Properties. Minerals are identified and described according to their physical properties of: Cleavage: The tendency of a mineral to break (cleave) along weak planes. Color: Most minerals have a distinct color while others are variable in color.
Minerals are classified by variety, species, series and group, in order of increasing generality. The basic level of definition is that of mineral species, each of which is distinguished from the others by unique chemical and physical properties.
Apr 11, 2017 · Chemical properties of minerals show the presence and arrangement of atoms in minerals. Using their chemical properties, minerals are identified by how they react to certain substances. 3. 1. SILICATE CLASS largest group of minerals • contains silicon and oxygen, with some aluminum, magnesium, iron an calcium • MAFIC (magnesium
Minerals have distinguishing physical properties that in most cases can be used to determine the identity of the mineral. In this course, you will develop a systematic approach to using the physical properties of minerals as identifying tools.

The five physical properties of rocks are color, luster, shape, texture and pattern. Not all rocks have the fifth property of pattern. These properties are visible and/or tactile. The color of a rock describes the hue or tone of the rock. Black, red, green or blue may be used to
Physical properties of minerals have distinguishing physical properties that in most cases can be used to determine the identity of the mineral this article, you will develop a ystematic approach to using the physical properties of minerals as identifying tools.If you follow this approach you should be able to identify most of the common
Physical properties Mineralogists have identified simple tests to help classify unknown minerals. Using the physical and chemical properties of minerals, you too can discover a minerals identity.
Minerals are classified on the basis of their chemical composition, which is expressed in their physical properties. This module, the second in a series on minerals, describes the physical properties that are commonly used to identify minerals. These include color,
PHYSICAL PROPERTIES OF MINERALS . The following are the important physical properties: i) Color . ii) Streak . iii) Lustre iv) Structure . v) Hardness vi) Specific gravity . vii) Cleavage viii) Fracture ix) Tenacity . x) Form . Color: Color is not constant in most of the minerals and commonly the color is due to stain or impurities in the
Physical Properties of Minerals. There are approximately 4000 different minerals, and each of those minerals has a unique set of physical 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.
