This chapter introduces: 1) mineral groups and the properties that allow us to distinguish different minerals; 2) some common rock-forming minerals in the Fells that are also common elsewhere; and 3) some not so conspicuous minerals in the Fells that are important to
Geologists have a very specific definition for minerals. A material is characterized as a mineral if it meets all of the following traits. A mineral is an inorganic, crystalline solid. A mineral is formed through natural processes and has a definite chemical composition.
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).
• Summarize the categories of minerals defined by anions or anionic groups. • Describe the types of configurations of silica tetrahedra found in silicate minerals. • Explain how minerals form.
Part III explores the range of naturally forming minerals and introduces hand specimen identifi-cation. It gives an overview of the various modes of mineral formation, and provides a background in thermodynamics to facilitate an understanding of mineral equilibria in geological environments and phase transformations.
within each group, minerals are grouped into families based on their internal atomic structure and then each family is subdivided into group of minerals having similar internal structure (i.e. iso-structural minerals).
