Industrial Minerals and Rocks, Volume 18
More than 4, naturally occurring minerals—inorganic solids that have a characteristic chemical composition and specific crystal structure—have been found on Earth. They are formed of simple molecules or individual elements arranged in repeating chains, sheets, or three-dimensional arrays. Minerals are typically formed when molten rock , or magma, cools, or by separating out of mineral-rich water, such as that in underground caverns. In general, mineral particles are small, having formed within confined areas such as lava flows or between grains of sediments. Large crystals found in geodes and other rocks are relatively rare. Rocks themselves are made of clusters or mixtures of minerals, and minerals and rocks affect landform development and form natural resources such as gold, tin, iron, marble, and granite. Silicates—including quartz, mica, olivine, and precious minerals such as emeralds—are the most common class of minerals, as well as the major components of most rocks.
It seems that you're in Germany. We have a dedicated site for Germany. Authors: Okrusch , Martin, Frimmel , Hartwig. This book presents a translation and update of the classic German textbook of Mineralogy and Petrology that has been published for decades. It provides an introduction to mineralogy, petrology, and geochemistry, discussing the principles of mineralogy, including crystallography, chemical bonding, and physical properties, and the genesis of minerals in a didactic and understandable way.
Chapter 2: Earth Materials
In this edition of Introduction to the Rock-Forming Minerals, most of the commonly occurring minerals of igneous, metamorphic and sedimentary rocks are discussed in terms of structure, chemistry, optical and other physical properties, distinguishing features and paragenesis. Important correlations between these aspects of mineralogy are emphasized wherever possible. The content of each section has been updated where needed in the light of published research over the 21 years between editions.
Geology can also include the study of the solid features of any terrestrial planet or natural satellite such as Mars or the Moon. Modern geology significantly overlaps all other Earth sciences, including hydrology and the atmospheric sciences , and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks.

Minerals are t he basic building blocks of rocks, which means rocks are made up of different combinations of minerals or just one mineral in some cases. Figure 2. Figures 2.
