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 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 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.
This Mineral Names Dictionary contains mineral names that the average mineral collector will encounter while collecting minerals, attending shows and visiting museum displays. In addition to the most common min‐ eral names, there are some unofficial names which you will still find on labels.
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
Mineralogic classification uses the types (Figure 1.2): felsic or silicic rocks, for example granite and rhyolite; intermediate rocks, for example granodiorite, diorite, dacite, and andesite; mafic rocks, for example basalt and gabbro; ultramafic rocks, for example peridotite and komatite.
• List the criteria required for a substance to be considered a mineral. • Explain how atoms bond within minerals. • Explain how mineral lattices influence the properties of minerals. • Summarize the categories of minerals defined by anions or anionic groups.
