Dear Colleagues,

We would like draw your attention to the following special session on the role of transtension on rupturing continental lithosphere (T09) at the Fall AGU Meeting in December, 2011.  This session is sponsored by the Tectonic (T) section and is cosponsored by Geodesy (G), Geomagnetism and Paleomagnetism (GP), Ocean Sciences (OS), Seismology (S), Volcanology, Geochemistry, and Petrology (V).

Preliminary invited speaker will be:
Joann Stock
Paul Mann
Zvi Ben-Avrham
Jolante Van Wijk


Session T09: Breaking by Shearing: the Role of Transtension in Rupturing Continental Lithosphere

Description: Rupturing continental lithosphere is a primary player in plate tectonics and a key to understanding continental lithosphere evolution. In general, it is assumed that magmatism is the leading mechanism for the rupture of continental lithosphere, but shear can also play a major role. For example, deformation in transtensional regimes can provide the necessary shear weakening for localization of deformation and rupture of continental lithosphere. In this session we look for contributions from observations and modeling to evaluate the role of shear in oceanic basin initiation both in the past (e.g. the role of Falkland Fracture Zone in opening of South Atlantic) and in recent time (e.g. Gulf of California).
