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 …[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, …[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 …[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 …[Read More]
There are not many scientific publications that tackle the issue of subjectivity in geological studies and its impact. In one of them, Baddeley et al. (2004), they state it clearly in some sentences: “the judgements of experts can be biased by their use of heuristics to guide the formation of their opinions” or “accepted or …[Read More]
When I graduated in the 80’s, a job in oil and gas was seen as a glamorous and exciting career for a geoscientist. Even some dramatic falls in the oil price could not dent the optimism within the industry, and oil cities like Calgary thrived. However, life for geologists working in our city has changed …[Read More]
It is always an interesting period when the time comes around for me to write my blog for the SSP page. My research is predominantly in numerical modelling, which would be interesting if I was modelling awesome natural phenomena, but I don’t. I general assess the sensitivities of the numerical models to different sorts of …[Read More]
