Hi Jan, You may well have seen the flyer for this meeting doing the rounds - i've been drafted in to try and get the Northern Hemisphere on board as the take-up from the USA/Canada/Europe has not been good despite a very good Aussie/S. African input to the meeting. I am now helping to run it and it is now a TSG meeting too. Any interest ? Bob OROGENESIS IN THE OUTBACK A look at cyclicity in orogenic belts July 12-16th 1999 Central Australia Organised by The Geological Society of Asutralia Specialist Group in Geochemistry, Mineralogy and Petrology The Northern Territory Geological Survey The Northern Territory Division of the geological Society of Australia IGCP-368 "Proterozoic Events in East Gondwana" and The Tectonic Studies Group (UK) The aim of this conference is to look at how the pre-existing geological character of orogenic belts can influence subsequent metamorphic and tectonic events. The conference would also look at issues such as what drives reactivation and remobilisation of terranes from small scale examples such as fault reactivation to larger scale examples such as the construction and destruction of mountain belts, as well as looking at why some terranes undergo a complex multi-stage geological evolution while others record very simple geological histories. Other issues to be addressed include the role of magmatism and fluids in the reactivation of terranes. Contributions will cover both a wide range of processes (metamorphic, structural, geochemical, geochronological, tectonic and geophysical) at different scales as well as a wide range of geological settings. The conference has been attracting a lot of interest from a number of countries and expressions of interest for this conference are now due. Forms can be submitted electronically via the conference home page located at http://www.earth.monash.edu.au/sggmp/sggmp.html. Full registeration and camera ready abstracts are due on the 1st of MARCH, 1999. Some of the proposed presentations include: Rejuvenation of the Continental Lithosphere: the convective thinning mechanism Cyclic P-T-age evolution of metamorphism in granulite regions Some observations on thermobarometry, reaction textures and polymetamorphism in UHT granulites Pan Gondwana metamorphism fluid flux and charnochitization: lower crustal signatures of terminal tectonic events in an orogenic belt Crustal growth, Metamorphism & Deformation in the Strangways Metamorphic Complex: a summary of recent U-Pb and Sm-Nd geochronology Brittle fracture patterns and reactivation in basement and cover rock sequences Tectonic Episodicity: The Result of non-linear feedback during continuous geological processes ? Reactivation of the Kaapvaal craton at greenschist-granulite grades: response to the Bushveld intrusion; numerical modelling of fluid flux and heat flow (with implications for mineralisation) Repeated Subduction events in the Alps Thermogravitational deformation during the emplacement of the Bushveld Complex, South Africa Proterozoic time-integrated history of fluid flow in the Reynolds Range The textural and rheological evolution of long-lived fault zones in orogenic belts Intraplate Orogeny and Lithospheric stability: implications for the Alice Springs Orogeny, central Australia The cordierite window on fluid-melt processes in high-grade metamorphism Diapirism in the Bushveld Complex contact aureole, South Africa Thermobarometry/geochronology of the Scandinavian Caledonides Pre and Post conference fieldtrips willl run to the northern and eastern Arunta Inlier respectively at a cost of AUD$600 each. Registration costs for the conference are $380 (SGGMP member academic), $400 (Non SGGMP member academic), $260 (SGGMP member student), $280 (Non SGGMP member student) - all prices in Australian dollars.
