Although joints can occur singly, they most frequently appear as joint sets and systems. A joint set is a family of parallel, evenly spaced joints that can be identified through mapping and analysis of their orientations, spacing, and physical properties. A joint system consists of two or more intersecting joint sets. [1] [2] [3]
The surface geology of Germany has evolved to its current configuration due to regional differences in the action and appearance of external and internal forces during the last c. 20 million years. Germany can be divided into three physiographic regions: the Central European Depression, the Central European Blocks and the Alps.
Historical geology or palaeogeology is a discipline that uses the principles and methods of geology to reconstruct the geological history of Earth. [1] Historical geology examines the vastness of geologic time, measured in billions of years, and investigates changes in the Earth , gradual and sudden, over this deep time .
Columnar jointing is a geological structure where sets of intersecting closely spaced fractures, referred to as joints, result in the formation of a regular array of polygonal prisms (basalt prisms), or columns. Columnar jointing occurs in many types of igneous rocks and forms as the rock cools and contracts.

This is a timeline of German history, comprising important legal and territorial changes and political events in Germany and its predecessor states. To read about the background to these events, see History of Germany. See also the list of German monarchs and list of chancellors of Germany and the list of years in Germany
For economic geology such as petroleum and mineral development, as well as research, modeling of structural geology is becoming increasingly important. 2D and 3D models of structural systems such as anticlines, synclines, fold and thrust belts, and other features can help better understand the evolution of a structure through time.
