Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2013 May 19. Visit to the Ries impact crater in Germany. You may have seen the recent news about the near-Earth flyby of a 2.7 km asteroid.
Fortunately the rock missed collision with the Earth, and continued its journey around the Solar System. However, in the past Earth has not been so lucky. Journal of Structural Geology - Shear zone geometry: A review. Section II: Kinematics and mechanics J.G.
Ramsay Geologisches Institut, ETH, CH-8092 Zürich, Switzerland. Journal of Structural Geology. Digital Geology: Earthquakes. Structural Geology by the Deformation numbers. Structural geologists seek to understand how rocks have changed shape, in order to better understand wider processes such as how mountains are formed.
Sometimes they use a terminology called ‘Deformation-numbers’ which I will now explain via a series of pretty pictures. Structural geologists spend their day measuring the orientations of things. These can be planar things, like sedimentary bedding, fault planes, cleavage planes and other metamorphic fabrics; or linear things like fold axes or mineral stretching lineations.
