PHYSICAL PROPERTIES OF MINERALS
The study of physical properties of minerals will enable you to make intelligent deductions about its crystal structure and chemical composition. For your information, physical properties of a mineral may be of great technological significance because a mineral may have important industrial uses that depend on its physical properties.

Vitamins and minerals: a brief guide
A mineral is an element that originates in the Earth and always retains its chemical identity. Minerals occur as inorganic crystalline salts. Once minerals enter the body, they remain there until excreted. They cannot be changed into anything else. Minerals cannot be destroyed by heat, air, acid, or mixing.
Properties of Minerals – Rocks And Minerals 4 U
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.

Lab 1 – Physical Properties of Minerals All rocks are composed of one or more minerals. In order to be able to identify rocks you have to be able to recognize those key minerals that make of the bulk of rocks. By definition, any substance is classified as a mineral if it meets all 5 of the following criteria:
Chapter 2 Minerals.ppt
2.3 Properties of Minerals Some minerals can be recognized by other distinctive properties. Distinctive Properties of Minerals A minerals properties depend on the elements that compose the mineral (its composition) and its structure (how its atoms are arranged).

Disruption of crystal lattice can decrease optical properties. The mineral may appear isotropic. Zircon and Allanite Colour in PPL . Due to absorption of selective wavelengths of light by electrons e.g absorption of red gives a green colour. May be diagnostic of the mineral e.g. green chlorite. Beware: biotite and hornblende may be either brown
Rocks and Mineral Identification Table
It is strongly recommended to the student of this book that he obtain specimens of rock, not labelled, and study their features with a view to naming them. The Table for Identification of Rocks will help in naming them. It may here be mentioned that the identification of rocks presents peculiar difficulties. Rocks are not definite substances; in some cases, they are mixtures of minerals, while

Each mineral has different physical and chemical properties. Physical properties you will use to identify the minerals include color, streak, hardness, luster, density, habit, cleavage, magnetism, fluorescence, and reaction to chemicals. Refer to Appendix 3 in the back of your book or any reference book for properties of common minerals.

Primary minerals: present in original rock from which soil is formed. These occur predominantly in sand and silt fractions, and are weathering resistant (quartz, feldspars); Secondary minerals: formed by decomposition of primary minerals, and their subsequent weathering and recomposition into new ones (clay minerals).
