TS Must-Read – Lister and Snoke (1984) S-C Mylonites

Following the impact of the global plate kinematics revolution, researchers in the 70s and 80s made significant efforts to compare records of deformed rocks in outcrops to large-scale deformation and kinematics. By publishing “S-C Mylonites” 1984, Gordon A. Lister and Arthur W. Snoke gave a step forward for the TS community. The paper contributed to transitioning from a strain-dominated framework ...[Read More]

Josefa Cuevas de Sansores (24-02-1920 – 2010) – Mexico’s first woman geological engineer

Josefa Cuevas Sansores was born on the 24th of March, 1920 to Andrea Aguilar Argüello. Andrea was a professor herself and graduated in 1929 specializing in ‘Instrucción Primaria Inferior y Superior’. She used the knowledge she had gained during her studies to found several kindergartens in Yucatán, one still carrying her name). Josefa had three older sisters, two of which became school teachers, w ...[Read More]

Mind your Head: An introduction to Workplace Bullying in Academia

Mind your Head: An introduction to Workplace Bullying in Academia

Understanding workplace aggression is a complex matter, and many questions arise when trying to tackle the issue. For instance, which acts and behaviours classify as workplace aggression, and when does something become workplace bullying or mobbing? How can you recognize if you or a co-worker/friend are the target of workplace aggression? How can you protect yourself and/or support others? What ca ...[Read More]

TS Must-Read – Davis et al. (1983) Mechanics of Fold-and-Thrust Belts and Accretionary Wedges

The establishment of plate tectonics in the 1960s triggered a reappraisal of the development of mountain belts and facilitated the physics-based understanding of mountain building processes. Many models for mountain building were, however, mostly conceptual, and there was no appropriate theory that described the first-order mechanics of mountain belts. In 1983, this gap was – at least partially – ...[Read More]

TS Must-Read – Tapponnier et al. (1982) Propagating extrusion tectonics in Asia: New insights from simple experiments with plasticine

In “Propagating extrusion tectonics in Asia: New insights from simple experiments with plasticine”,  Tapponnier and co-authors (1982) describe one of the most famous analogue experiments in the history of Earth Sciences. The experiment was performed in the laboratories of Rennes (France), at the beginning of the ‘80s. The article aims to shed light onto the large-scale effects caused by the India- ...[Read More]

TS Must-Read – Boyer & Elliot (1982) Thrust systems

The now-classic paper of Boyer & Elliott (1982) presented a novel and general geometric framework to study thrust systems. The framework describes thrust surfaces by lines of contact between thrusts, or branch lines, and lines of thrust termination, or tip lines, and examines how they join into imbricate fans or duplexes. The framework allows accurate and succinct descriptions of the geometry ...[Read More]

Janet Vida Watson (1 September 1923 – 29 March 1985): The woman who could translate the story of Precambrian rocks into a crystal-clear message

On a late summer day in September 1923, Janet Vida Watson was born. With a father working in palaeontology and a mother who did research in embryology until her marriage, Janet grew up with science all around her. She went to South Hampstead High School, known for its science teaching and continued her education in General Science at Reading University. She graduated in biology and geology in 1943 ...[Read More]

Features from the Field: Shear Zones and Mylonites

Features from the Field: Shear Zones and Mylonites

The San Andreas Fault in California, the Alpine Fault in New Zealand, or the Main Frontal Thrust in the Himalayas are some of the most famous and largest fault zones that accommodate the relative displacement between two adjacent crustal blocks. Such faults, however, represent only the shallower expression of something much bigger: a crustal shear zone. In the first 10 kilometers or so of the crus ...[Read More]

TS Must-Read – Ramsay (1980) Shear zone geometry: a review

TS Must-Read – Ramsay (1980) Shear zone geometry: a review

Ramsay’s 1980 important contribution is a practical and theoretical handbook about shear zones, where the reader can find a detailed classification of shear zones, their description, and mathematical explanation. A definition of the concept of shear zones opens the article, followed by the shear zones classification into three types, namely brittle (e.g., Fig. 1a), brittle-ductile (e.g., Fig ...[Read More]

TS Must-Read – Brace and Kohlstedt (1980) Limits on Lithospheric Stress Imposed by Laboratory Experiments

In 1980 Brace and Kohlstedt published a short paper that constrains the strength of continental lithosphere by extrapolating laboratory measurements of rock strength to geological conditions. Their approach follows earlier work by Goetze and Evans (1979) and relies on two key considerations. First, the brittle strength is given by the frictional strength of rocks following Byerlee’s law (Bye ...[Read More]
