Scientific objectives:

This working group, would like to focus on five questions that are likely of large interest to the Earth sciences community:
- How do large and mega- transform domains react to both far- and near-field stress changes?
- How do transforms interact with the underlying mantle. What are the effects of temperature, rheology and composition?
- What is the interplay between transform dynamics and magmatism?
- Which relationship exist between oceanic transform faults and their counterparts on continental margins?
- Are oceanic transform faults sites of intense fluid-rock interaction and biogeochemical exchange?

EGU 2019 Session: Oceanic and continental transform faults: towards a multi-disciplinary approach

Oceanic and continental transform faults: towards a multi-disciplinary approach
Convener: João C. Duarte
Co-Conveners: Daniele Brunelli, Barry Hanan, Marcia Maia, Mathieu Rodriguez

This session is promoted by the Oceanic Transform Faults working group of InterRidge and aims to present recent results on studies of these large features, especially on the rheology, deformation patterns, rupture processes, fluid circulation and physical properties of transform faults. We welcome observational studies on strike-slip and transform faults, both continental and oceanic, on fracture zones and on transform continental margins

Final Report from the Workshop of The InterRidge Working Group "Oceanic Transform Faults"

Forty-two international scientists participated in the two and a half day (22 to 24 May 2018) workshop held at the campus of the Institut Universitaire Européen de la Mer (IUEM), Plouzané, France. The meeting began with a series of keynote talks and poster presentations covering different subjects such as global characterization of transform faults and their relation to mid-oceanic ridges and different approaches to understand, discover, and model processes active at transforms and fracture zones.

Brief report from IR OTF Workshop

The first workshop of the InterRidge Working Group on Oceanic Transforms took place from 22nd to 24th May in Brest/Plouzané (France). The workshop was attended by 40 international scientists from 7 specialities. Five attendants were supported by InterRidge travel bursaries: 3 from USA, 1 from China and 1 from Germany.

Final program of the IR OTF Workshop

Dear Participants and Speakers,

Please find enclosed a final program of the workshop.

All talks are in the first day but two on Wednesday morning.

Looking forward to meet you all in Brest, we wish a very fruitful workshop and nice time

InterRidge Workshop on Oceanic Transform Faults

Forty-nine scientists have registered to the InterRidge Workshop on Oceanic Transform Faults held from 22nd to 24th May 2018 in Brest/Plouzané (France). The lists of participants and of keynote speakers are on-line, please visit the workshop website to find the most important information.<--break->

First WG OTF Workshop, IUEM, Plouzané, France, 22-24 May 2018

The workshop will be held at IUEM from 22 to 24 May 2018. The institute is located at the city of Plouzané, near Brest, on the western coast of France near the entry of the Brest bay. From the Pointe du Diable (Devil’s Point) the view on the cliffs of the Brittany west coast is breathtaking! Especially in May, when the weather is often sunny and (relatively) warm.
