1.1 INTRODUCTION. Rocks are naturally occurring aggregates of one or more minerals. In the case of porosity or fracturing, they also contain fluid phases. With respect to their geological genesis and processes, rocks are divided into three major groups: igneous rocks (magmatites); metamorphic rocks (metamorphites); sedimentary rocks (sediments).
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.
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
