Thus, joints are important to the economic and safe development of petroleum, hydrothermal, and groundwater resources and the subject of intensive research relative to these resources. Regional and local joint systems exert a strong control on how ore-forming hydrothermal fluids (consisting largely of H 2 O , CO 2 , and NaCl — which formed ...
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.
Columnar jointing in Giant's Causeway in Northern Ireland Columnar jointing in the Alcantara Gorge, Sicily. 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.

Early 2013, the BGR employed a total of 795 employees. The BGR, the State Authority for Mining, Energy and Geology and the Leibniz Institute for Applied Geophysics form the Geozentrum Hanover. All three institutions have a common management and infrastructure, and complement each other through their interdisciplinary expertise.
Structural geology is the study of the three-dimensional distribution of rock units with respect to their deformational histories. The primary goal of structural geology is to use measurements of present-day rock geometries to uncover information about the history of deformation ( strain ) in the rocks, and ultimately, to understand the stress ...
