   Announcement for the Conference


  • Deadline for ABSTRACT Submission: April 15
  • Deadline for REGISTRATION: May 1



 TRIGGER ("Trans-disciplinary Research on Iranian Geology, Geodynamics, Earthquakes and Resources") is an International Scientific Coordination Network meant to pursue and develop the collaboration between Iran and France in the field of geology/geodynamics, earthquakes (and hazard assessment) and mineral resources.

This network rests on collaborations already well established at the start of the millenium (such as between the Geol. Survey of Iran, NCC, IIEES,… and the universities of Paris, Montpellier, Strasbourg, Grenoble...) but with a broader scope and more participants, both on the Iranian and french sides. It is actively supported by the CNRS (the national research center of France) through the Institut des Sciences de l'Univers (INSU; "GDRI" programme). Participation of scientists other european countries is also foreseen.

The present-day institutional partners of TRIGGER include:

   UPMC (Univ. P.M. Curie), Paris — Coord: Philippe Agard, Professor

   Ecole Observatoire des Sciences de la Terre, Univ. Strasbourg

   Laboratoire Géosciences, Univ. Montpellier

   Laboratoire ISTerre, Univ. Grenoble

   Laboratoire Géoressources, Univ. Nancy

   CEREGE Aix-Marseille

For the Iranian side:

   Geological Survey of Iran (GSI) — Coord: Jafar Omrani, Senior Researcher

   Research Institute for Earth Sciences (RIES)

   National Cartographic Center (NCC, Tehran)

   Institute of Advanced Studies in Basic Science (IASBS, Zanjan)

   International Institute of Earthquake Engineering and Seismology (IIEES, Tehran)

   Universities of Tehran and University of Birjand

   Research Institute for Applied Sciences (RIAS)



Description of the Scientific Theme

The scientific scope of the Network, promoting trans-disciplinary research on Iranian Geology, Geodynamics, Earthquakes and Resources is threefold and comprises:


            1. Geodynamics:

The Iranian mountain belts and plateau range amongst some of the most geologically active regions of the world, whilst offering unrivaled outcropping conditions. This unique combination allows studying short- and long-term deformation processes, magmatic processes and the origin of mineral deposits, as well as large-scale plate tectonic dynamics (Iran notably provides a continuous geological record of convergence and closure of the Neotethyan realm). The multidisciplinary approach of the network ( field to models, present to past) is meant to tackle such processes as present-day deformation at large- and small scale, deformation partitionning the Neogene to present, tectonic inheritance and subduction processes, nature and emplacement mechanisms of ophiolites, basin formation (and fluid migration), and magmatic evolution, particularly over the last 50 My which largely contributed to the mineral wealth of Iran.


            2. Seismic (and gravitational) hazard:

Iran is one of the most seismically active intracontinental domains in the world, with earthquakes nesting in mountain belts as well as along the numerous major strike-slip faults that cut across the country. The vulnerability of major citites such as Tehran and other large cities (Tabriz, Mashad, Ispahan,…) is a major challenge for risk assessment. Research efforts of the network combine space geodesy, seismic instrumentation and paleoseismology (including the analysis of geomorphic features and surface datings), using both permanent instrumental arrays in Iran and temporary arrays to construct a very large database with dense (instrumental and paleosismological) time series. Local and regional studies are devoted to estimating seismic and gravitational hazard in a probabilistic way.


            3. Mineral resources:

In addition to oil and gas reserves, Iran hosts a wealth of metal resources (notably copper, iron and zinc), a large part of which is tightly linked to Tertiary magmatism in Central Iran and adjacent belts, or to ophiolites. Chromium, platinum group metals, rare earth elements (but also iron or gold) abund across the country. Some resources are also associated with Mississippi Valley Type deposits (F, Ba, Pb, Zn). Research efforts of the network are devoted to refine (or establish) the petrological and tectonic model for ore genesis, with implications for future mining operations and economic development.


Scientific domains covered by the Network:

Geodynamics (structural geology, petrology, geochemistry, geochronology, stratigraphy, space geodesy, seismic imaging, seismology, paleoseismology, fully-coupled thermo-mechanical numerical modelling); Natural hazards (seismic, gravitational); Mineral resources (ore mineralogy, fluid composition and speciation).
