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.
The Physical properties of minerals are used by Mineralogists to help determine the identity of a specimen. Some of the tests can be performed easily in the field, while others require laboratory equipment. For the beginning student of geology, there are a number of simple tests that can be used with a good degree of accuracy.
Dec 28, 2018· Minerals each have their own specific chemical composition and structure that gives them distinction from other similar minerals. They also have specific physical properties that scientists can use to identify them without resorting to looking at them under a microscope.
A mineral is a naturally-occurring, inorganic solid which possesses a characteristic internal atomic structure and a definite chemical composition. ... Substances that have these features will also have distinctive physical properties such as color, crystal form, cleavage, luster, streak, etc.

Physical Property Definition Share Flipboard Email ... The two classes of physical properties are intensive and extensive properties. An intensive property does not depend on the amount of matter in a sample.
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, …
Minerals are naturally occurring inorganic substances of more or less definite chemical composition, displaying more or less definite physical properties. As the basic constituent of rock, minerals control much of rock behavior.
Physical Properties of Minerals . The physical properties of minerals are a direct result of their chemical and structural characteristics. Because they are readily determined (i.e., by examination or simple tests), they are important to the rapid identification of minerals. Other methods for studying minerals involve more elaborate tests (e.g ...
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.

Weathering is the combination of processes that breaking down of rocks, soil and minerals, eventually transforming into sediment. On the other hand, disintegration or alteration of the rock surface in its natural or original position through physical, chemical and biological processes induced or modified by wind, water and climate.
electron microscopes, we identify minerals by visual and chemical properties called physical properties. • Types of physical properties that geologists use include: – Color, Streak, Luster, Hardness, Specific Gravity, Crystal Habit, and Cleavage Pyrite • Properties depend upon… – Chemical composition. – Crystal structure.
Minerals embody numerous physical properties, which make them much more interesting and complex than commonly perceived. Several of these properties are essential in mineral identification. With enough experience, a mineral can often be accurately identified by simply viewing it.

The physical properties of minerals are related to their chemical composition and bonding. Some characteristics, such as a mineral's hardness, are more useful for mineral identification. Color is readily observable and certainly obvious, but it is usually less reliable than other physical properties.
The physical properties of minerals include various measurable and discernible attributes, including color, streak, magnetic properties, hardness, crystal growth form, and crystal cleavage. These properties are mineral-specific, and they are fundamentally related to a particular mineral's chemical make-up and atomic structure.
