In 1976 Oriol Riba published his paper on “Syntectonic unconformities of the Alto Cardener, Spanish Pyrenees: a genetic interpretation”, and despite appearing as a niche topic at first glance, it was voted as one of the papers in our Must-Read series. A major reason for that is that the paper presents a general model for …[Read More]
It has been many months since the first lockdown, in some countries about a year, in other countries perhaps eight months. A continuing learning curve, with many ups and downs. Now the end is slowly appearing on the horizon, with promises of vaccines, and several countries making definite plans on when and how to vaccinate. …[Read More]
Long after the first attempts made by Wegener (1915), the theory of plate tectonics was progressively accepted by the Earth sciences community in the thrilling ‘60s thanks to observations from mid-ocean ridges (see TS-must-read blogpost of September 2, 2020; Dietz, 1961; Heezen and Tharp, 1965, Hess, 1962; Vine and Matthews, 1963). The question is then, …[Read More]
In his 1968 paper “Rises, Trenches, Great Faults, and Crustal Blocks”, Jason Morgan added the missing pieces of the plate tectonics: the representation of plates’ motion in terms of spherical surface, and plate rigidity. In the very first lines of the paper he describes his contribution as an “extension of the transform fault concept [of …[Read More]
San Francisco has been a natural gathering place for people across the millennia. It is not a coincidence that this city, situated at the entrance to the largest estuary on the U.S. West Coast, owes its dramatic setting to active geology on the North American plate margin. The first people of the San Francisco Peninsula, …[Read More]
Franciszka Szymakowska was born on the 5th of February in 1927 in Krakow. She was lovingly known as “Niusia” (Antoni 2007). About her early life, not much is known. Franciszka did her studies at the Faculty of Mathematics and Natural Sciences of the Jagiellonian University and graduated in 1952. During her studies, she started …[Read More]
This Mind Your Head blog post is a follow-up from Jean Holloway’s talk during the online short course on mental health that aired during the last EGU General Assembly, where she discussed overcoming anxiety. Anxiety is excessive worry or fear, and is a normal part of life, until it becomes frequent or debilitating. This post is written …[Read More]
Chi Jishang was born on the 25th of June 1917 in the Anlu County in the Province of Hubei, central China, but she moved to Beijing when she was four years old. Because her family was poor and she had three older siblings, her parents did not allow her and her younger sibling to go …[Read More]
An angular unconformity is an erosional surface that truncates older, tilted sedimentary layers and that is overlain by younger layers, oriented parallel to the unconformity. The discovery and interpretation of angular unconformities, like the famous Hutton’s unconformity at Siccar Point, Scotland, marked a paradigm shift in the geological theories of the 18th century. At that …[Read More]
