Granulites and Granulites – History

‘Granulites and Granulites’ (G&G) has been running in its current form since 2006. The conference was a natural progression to a major symposium of the same name, which formed part of a GAC/MAC/CGU Meeting in Ottawa, Canada, in 1986. The first G&G meeting, organized by a joint US–Brazilian team led by Mike Brown, was held at the University of Brasilia, Brazil, 10–12 July. The meeting was preceded by a fieldtrip to examine high-pressure granulites in Andrelandia, Minas Gerais, and followed by a trip looking at ultrahigh-temperature granulites of the Barro Alto and Anapolis-Itaucu Complexes, Goias.

The second G&G, ‘Granulites, partial melting and rheology of orogenic lower crust’, was held from 13–15 July 2009 in the Hrubá Skála Chateau, Czech Republic, and was organized by a diverse international team led by Karel Schulmann. The meeting was preceded by an excursion to examine granulites of the Saxony granulite massif, Erzgebirge and Egger complex, and the South Bohemian granulite massifs. The post-conference field excursion was to the St. Leonhard granulite massif, the Gföhl unit and the associated rocks at the eastern margin of the Bohemian massif.

The third iteration of G&G series was held on 16–19 January, 2013, at the National Geophysical Research Institute, Hyderabad, India, and organised by a joint Indian–Australian team led by Ian Fitzsimons. A pre-conference fieldtrip examined UHT rocks of the Eastern Ghats Province. The trip that followed the meeting looked at rocks of the Southern Granulite Terrane, the home of charnockite.

Most recently, G&G returned south of the equator, to Windhoek, Namibia from 26–29 July, 2015. The meeting, organized by Johann Diener and Dick White, was preceded by a trip to examine the Mesoproterozoic Aus granulite terrain in southern Namibia, to demonstrate processes of melt production, residence, accumulation and extraction from low-pressure granulites. The post-conference trip was to the Central Zone of the Damara Belt, focussing on melt transfer networks through near-solidus rocks and fluid-fluxed melting in upper amphibolite facies rocks.
