The Canyonlands National Park, Utah, is famous for its beautiful landscape and spectacular landforms. For many geoscientists it is also well-known as a sandstone reservoir analogue and as a tourist you’ll often run into groups of geologists on field trips. It’s a matter of debate how and how fast the beautiful grabens in the Needles Fault zone formed – these are large arcuate canyons several tens of kilometres in length, paralleling the Colorado River. In a new paper we present results from remote sensing, mapping, and georadar (GPR). Our aim was to better understand the coupling between deformation, erosion and deposition in such an active system. Based on our findings we developed a model of graben formation and describe the geometry of the dilatant faults at depth. We argue that either the grabens are older than previously assumed or that sedimentation rates were much higher in the Pleistocene.
Some weeks ago we advertised the NSF-sponsored workshop on Future Directions in Tectonics. Yesterday, Kevin Mahan announced that the workshop will be postponed. Read the message he circulated: Continue reading “Meeting postponed: NSF workshop on Future Directions in Tectonics”
The workshop “Tectonic and geodynamic evolution of Eastern Iran” will be held in both Tehran (2 Nov) and Birjand (3-6 Nov). It will comprise 3 days of field excursion around Birjand showcasing the variety of Sistan’s geological highlights (from ophiolites, deformation events, sedimentary basins to ore-mineralizations), that will be open to ~60 people. Continue reading “Workshop ‘Tectonic and geodynamic evolution of Eastern Iran’, 2-6 November, 2015”
Future research in tectonics and structural geology is the focus of an NSF-sponsored workshop to be held in Madison, Wisconsin on July 22-24, 2015 – aimed to assemble a diverse range of earth scientists to identify pertinent and promising areas of new research, recognize and prioritize infrastructure needs that are necessary to making scientific progress, and articulate the societal relevance of research in tectonics and structural
geology in the 21st Century. The vision articulated at the workshop will be captured in a white paper, the first of its kind since 2004, that will inform our science community, funding agencies, elected officials, and the general public.
Our colleague Manuel Díaz-Azpiroz from Seville and his colleeagues will be guest editor of a special issue on “Tectonics of Oblique Plate Boundary Settings”, which is going to be published in Tectonophysics.
Everyone who is interested to participate may submit a manuscript. The Special Issue aims on contributions about different aspects of the study of convergent and divergent, ancient and active oblique plate boundary systems, including analytical, numerical and analogue modelling methods, as well as field-based analyses of natural cases. Innovative approaches that exploit new analysis techniques (3D geophysical modelling, space geodesy-based kinematics, etc.) or methods combining structural geology with geophysics, petrology, geomorphology or stratigraphy are also welcomed. Through this thematic volume of Tectonophysics, the progress in the understanding of the kinematics and dynamics of oblique plate boundaries will be addressed and innovative and/or multidisciplinary research methods that provide new insights into the 3D deformation inherently linked to these systems will be promoted.
The GeoFrankfurt conference took place a few days ago. Due to the large amount of work presented on Eastern Mediterranean Tectonics, a special issue on this topic will be published in the International Journal of Earth Sciences (former Geologische Rundschau). Paris Xypolias allowed me to circulate the call for papers: Continue reading “Call for papers: Special Issue of the International Journal of Earth Science on Eastern Mediterranean Tectonics”
The second day of the meeting revealed very nice and interesting talks of the Korean geologists and paleoseismologists, which was an excellent preparation for the upcoming post-meeting field trips on the following days. Talker of the day was Dr Tom Rockwell, he gave three talks and lectures, however one as replacement for Bill Lettis, who wasn´t able to come to Korea. Before dinner a traditional Korean drum and percussion show opened our ears and eyes for this beautiful and sometimes mysterious country. This closing dinner outside Busan was very special, in a kind of museum with a terracotta choir of a million voices, and….

A new book on paleoseismology, archaeoseismology and earthquakes on the Iranian Plateau has been published in the Developments in Earth Surface Processes series. Volume 17 is dedicated to Earthquakes and Coseismic Surface Faulting on the Iranian Plateau A Historical, Social and Physical Approach, and it is authored by Manuel Berberian. The book not only covers physical processes related to earthquakes in Iran like coseismic offsets, archaeoseismological effects, and geomorphological evidence, but its first part is all about Earthquake Hazard Warning in Oral Tradition and Literature on the Iranian Plateau. The volume comes with a foreword by Robert Yeats and Roger Bilham. Table of contents:
Good news for students interested in a PhD on tectonics in New Zealand: John Townend announced that several scholarships are available. Deadline for application is 1 July 2014.
PhD students are sought to work on several seismological and geophysical topics within the Institute of Geophysics, School of Geography, Environment, and Earth Sciences, Victoria University of Wellington (VUW). The geophysics group at Victoria University of Wellington has an established track record of research in seismology, tectonics, crustal geophysics, and structural geology. In the most recent Performance-Based Research Fund (PBRF) evaluation, Victoria University of Wellington was ranked first in New Zealand for research excellence and was also ranked first in New Zealand in Earth Sciences.

The new open access journal Frontiers in Earth Sciences recently appeared. Its first published article in the Structural Geology and Tectonics section is an overview piece by Chief Editor Agust Gudmundsson about Great challenges in structural geology and tectonics. The article provides a nice round-up of some basic questions in tectonics that are still not well enough understood and which definitely need to be addressed in the (near) future. It starts from questions which sound easy to be answered (How many tectonic plates are there?), but actually aren’t.
