John G. Ramsay1 wrote his seminal textbook on the folding and fracturing of rocks in 1957, almost 20 years before I was born (and I don’t count myself as young!). So why did I co-convene a session at EGU in 2017 to celebrate the book? Because the book, in many ways, expresses the legacy that John has given to structural geology. He followed it with a series of books of the same ilk – Ramsay ...[Read More]

Only a few more days and the General Assembly of the EGU 2017 will start! Five exciting days with science and the opportunity to meet your colleagues and collaborators, both the old and the new. Earlier this week the outgoing TS President Susanne Buiter and the incoming TS President Claudio Rosenberg posted a blog with TS highlights, but what are the must-see for the Early Career Scientists? This ...[Read More]

Highlights at EGU 2017 from the division for Tectonics and Structural Geology

Susanne Buiter and Claudio Rosenberg April 18, 2017

Susanne Buiter (outgoing TS president, Geological Survey of Norway) and Claudio Rosenberg (incoming TS president, UPMC France) It is with great pleasure that we write this blog welcoming everyone to EGU’s upcoming General Assembly in Vienna, and especially to the many events organised by our division for Tectonics and Structural Geology! We are highlighting some of the week’s many events below, th ...[Read More]

Features from the field: Strike Slip Faults Classification

Mehmet Köküm April 17, 2017

A strike slip faults is a fault on which most of the movement is parallel to the fault strike (Bates and Jackson, 1987). The term ‘wrench fault’ is also popularized in some researchers. Sylvester (1988) suggest not using wrench fault term for defining strike slip fault as general term because wrench fault was defined by Anderson (1905) as deep seated, regional and vertical faults. Many major strik ...[Read More]

Minds over Methods: Reconstruction of salt tectonic features

What is the influence of salt tectonics on the evolution of sedimentary basins and how can we reconstruct such salt features? Michael Warsitzka, PhD student at the Friedrich Schiller University of Jena, explains which complementary methods he uses to better understand salt structures and their relation to sedimentary basins. Enjoy! Reconstruction of salt tectonic features from analogue mode ...[Read More]

How can we learn more about the Earth’s interior by going into space? This edition of Minds over Methods discusses using satellite data to study the Earth’s lithospere. Anita Thea Saraswati, PhD student at the University of Montpellier, explains how information on the gravity of the Earth is obtained by satellites and how she uses this information to get to know more about the lithospe ...[Read More]

Features from the field: Growth Faults

Mehmet Köküm January 30, 2017

Displacement rate along the fault is not same.

Growth faults are syndepositional or syn-sedimentary extensional faults. Growth faults develop when sediments are being deposited, are key elements in understanding deformation processes. Indeed, successively deposited sedimentary layers are involved in the different stages of the growth of the structure and produce a record of the deformation history. Their fault plane dips mostly toward the basi ...[Read More]

Have you ever thought of using gelatin in the lab to simulate the brittle-elastic properties of the Earth’s crust? Stefano Urbani, PhD student at the university Roma Tre (Italy), uses it for his analogue experiments, in which he studies the controlling factors on dike propagation in the Earth’s crust. Although we share this topic with our sister division ‘Geochemistry, Mineralogy ...[Read More]

Introducing the people behind the TS division

Elenora van Rijsingen December 2, 2016

This week we present the many volunteers behind the activities of the Tectonics and Structural Geology (TS) division. We can also be found on http://www.egu.eu/ts, Facebook and twitter. We are always happy to hear new ideas and feedback! Just drop a message on ts@egu.eu and don’t forget to stop by the division meeting during the General Assembly in April next year.

Publishing in Solid Earth: interview with Anna Rogowitz

TS team November 18, 2016

Following our previous blog about the EGU journal Solid Earth, we now would like to share some experiences of open access publishing in this journal with you. Therefore, we interviewed Anna Rogowitz, who recently published in Solid Earth, about her experiences. About Anna: Anna is an Assistant Professor in the Structural Processes Group at the Department of Geodynamics and Sedimentology (U ...[Read More]
