In recent months, I had the opportunity to work on a project analysing subsurface data from a rock sequence previously interpreted as the product of an estuarine depositional environment. The client sought subsurface maps to characterize the spatial distribution of various geobodies associated with sedimentary deposits typically found in modern estuaries. In other words, the goal was to reconstruc ...[Read More]
Most people would not relate Central Europe to a tropical environment today. During the Middle Jurassic (174-163 Ma ago), however, such conditions prevailed in most parts of the nowadays landmass that was almost completely covered by a shallow epicontinental sea (estimated 0-100 m water depth) except for several emerged areas and islands. During this time, the continent of Pangaea broke apart, as ...[Read More]
The area were most collapses occurred is a former alluvial outlet for the drainage of water and sediment from the upper parts of the Ahir Mountain When it comes to earthquakes, the nature of the Earth surface geology and its geometry is critical to understand the intensity and type of motion of the ground where we live. Of course, other factors matter when assessing the risk of damage in human-mad ...[Read More]
From sketches to first photos Knowledge of geology and, in particular of sedimentology, has successfully been transferred and shared for hundreds of years through sketches. Like a botanist or zoologist, a geologist is able to record data from the field with just a paper and a pencil in the form of drawings (see one of the earliest published sketches of an outcrop in Figure 1). Geological maps and ...[Read More]
