Author: Simon Blondel (OGS Trieste) Giant, halite-dominated salt accumulations are common on Earth. Throughout the human history, they have been mined for their salt that was used for animal nutrition, food conservation, de-icing etc. Compared to the other rocks, halite itself is quite a peculiar material characterized by: a low density;a low permeability;a high solubility … Continue reading From Fossil fuel exploration to underground storage and geothermal energy: Why do we care about Salt tectonics?
Authors: Hanneke Heida (ICTJA, CSIC - Barcelona), Fadl Raad (CNRS Montpellier) and Athina Tzevahirtzian (Universitá di Palermo). Last September our ESRs Hanneke Heida, Fadl Raad and Athina Tzevahirtzian had the opportunity to enjoy an Indian Summer investigating the fascinating Messinian outcrops of the island of Mallorca, in the Balearic archipelago. Hanneke, Athina, Fadl and Professor … Continue reading The rugged reefs of Mallorca: the key to the Messinian story in the Western Mediterranean?
Author: Gaia Travan (CNRS Lille, France) What makes the salt a unique geological material is its low viscosity value: at low temperature and considering geological times, salt moves as a Newtonian fluid. To have an idea of the viscosity contrast between salt and brittle rocks as carbonates, the difference in viscosity can be higher than … Continue reading Brief history of the salt tectonics studies
Author: Beatriz Martínez-Rius (Sorbonne Université, Paris) I bet that all of us have tried to imagine how the Mediterranean looked like 5 million years ago. We’ve tried to draw it, model it, animate it, and depict it through scientific representations of all sorts. When we talk about partial desiccation, reflooding, isolated basins… we are exercising … Continue reading Imagining the Mediterranean’s past: Why historians of science should take imaginaries into account?
Author: Simon Rowendaal (Universitat Hamburg, Germany) A personal reason for me to go into geology was my dream to become an astronaut. I was therefore very excited when in May 2019 the U.S. announced its plan to return to the Moon by 2024. When man will set foot on the lunar surface again, among them … Continue reading Why Geologists Become Astronauts
Author: Hanneke Heida (ICTJA - CSIC, Barcelona) One of the most challenging aspects of earth sciences is the linking of processes occurring on vastly different scales, from the local to the global, the microscopic to the solar system, the second to millions of years. Sometimes fascinating clues to a large and seemingly ungraspable phenomenon can … Continue reading Falling seas or Rising lands? The discovery of glacio-isostatic adjustment
Author: Francesca Bulian (Universidad de Salamanca, Spain) When mankind started populating Planet Earth, it was immediately encountered with extraordinary events that it could not fully explain or understand on its own such as great storms, lightning and thunder, earthquakes, volcanic eruptions, floods…. However, like we continue doing today, it is in our nature to seek … Continue reading Noah’s flood: did something similar happened in the Mediterranean 5.33 Million years ago?
