PURPOSE OF MEETING
Precambrian high-grade mobile belts (PMB) are major crustal structures preserved in ancient cratons or along their margins. Well-known PMBs are widely distributed all over the world, including Lapland-Belomorian (Fennoscandian Shield); Limpopo, Ubendian, Namaqua–Natal, Mozambique (African Shield); Southern Granulite Terrane, Eastern Ghats (Indian Shield); Trans North China Orogen, Khondalite belt (North China craton); Stanovoy (Aldan Shield); Musgrave Range (Australian Shield); Grenville, Kapuskasing uplift (North American Shield); Itabuna-Salvador-Curaca, Brasilia, Ribeira, Dom Feliciano (Brasilian Shield); and Enderby Land, Rayner (Antarctic Shield). The distinctive features of PMB’s are large-scale, multiphase HP-UHP and HT-UHT metamorphic processes, and intense and multiple deformation. The deep crustal and lithospheric structure of PMBs differs from that of Archaean cratons in both thickness and internal architecture. At the same time, protoliths of some PMBs comprise rock associations similar to the volcano-sedimentary assemblages of greenstone belts and TTGs characteristic of Archaean cratons. PMBs should be distinguished from lower-grade Precambrian orogenic belts such as the Svecofennian (Fennoscandian Shield), Ketilidian and Trans-Hudson (North American Shield), which formed similar to modern accretionary orogens.
In spite of a great progress in the study of PMBs, there are some major unsolved problems the most significant of which will be discussed at the conference:
English. Questions and discussions will be simultaneously translated into Russian
15 December 2013 - 20 February 2014: Accepting applications for attendance (with title of presentation). 1 May, 2014: Deadline for submission of abstracts. 15 May, 2014: Circulation of Conference Programme. 12-15 June, 2014: Pre-conference field trip. 16 June, 2014: First day of registration of attendees. 17-19 June, 2014: Conference. 19-23 June: Post-conference field trip.
Citizens of most countries will require an entry visa to visit Russia. The Institute of Geology, KarRC, RAS, will provide participants with all papers required for visa application. It takes about two weeks in Petrozavodsk to obtain some of the official papers required for visa applications. Therefore, please request these papers from the Organizing Committee at least one month prior to your visit.
