Minerals may be identified by different physical and chemical properties. It is important to understand that a minerals is usually identified by a variety of properties. No single property is diagnostic for all minerals. Common diagnostic properties include: •Color •Streak •Luster •Hardness
Minerals differ from rocks, which are naturally occurring solids composed of one or more minerals. Rocks do not have a distinctive chemical composition or crystal structure. The earth science definition, however, is not always used to define minerals.
Minerals: Their Constitution and Origin is an introduc-tion to mineralogy for undergraduate and graduate students in the fields of geology, materials science, and environmental science. It has been designed as a textbook for use on a semester course and covers all aspects of mineralogy in a thoroughly modern and integrated way.
Minerals are defined as: naturally-occurring, inorganic, solid materials, with a crystalline structure, and a well-defined chemical composition that can be written as a chemical formula. Geologists give proper names to different minerals.
The science of mineralogy is a branch of the ea rth sciences that is concerned with studying minerals and their physical and chemical prop erties. Within mineralogy there are also those who study how minerals are formed, where they ar e geographically located, as well as their potential uses.
Define: What is a mineral: A solid with a highly ordered atomic arrangement and a definite (but not necessarily fixed) homogenous chemical composition. Highly ordered atomic arrangement: internal structural framework of atoms/ions
Minerals. Naturally Occurring - minerals must be formed naturally - glass, concrete, synthetic diamonds, rubies and emeralds don’t count. Inorganic - minerals are not formed by anything that was ever alive. Therefore, materials such as: Ivory, Amber, Coal, Pearls are not minerals! Crystalline.
