By Alain Godard, Jean-Jacques Lagasquie, Yannick Lageat, Y. Gunnell

The basement areas represent greater than two-thirds of outcropping bedrock fabric throughout our planet's continents. up to now 30 years French geomorphologists have contributed drastically to the characterization of a few of the legislation and styles of landform evolution in shields and crystaliine parts with altering bioclimatic environments. This quantity displays the quest for a greater figuring out of landscapes and landforms in igneous and metamorphic terrains at various latitudes. in addition, it covers a large box of research accrued on 4 continents and addresses the problem at a variety of spatial and timescales. it truly is a fantastic quantity not just for post-graduate geomorphology scholars but additionally for geoscience students enthusiastic about igneous petrology, quaternary geology, actual geography, soil technology and land use planning.

Evidence suggests, in several cases of low- as well as high-elevation passive margins, that deformation of the basement by updoming may take effect some considerable time after the continental margin was fragmented into asymmetric half-grabens by faulting. North Atlantic margins exhibit many examples of this (Godard 1982a),and the morphological simplicity of the Labrador passive margin uplift is particularly demonstrative in this respect (Andre 1983).

The key to an und erstanding of the denudation ch ronologies for each massif and , ultimately, for the entire Europ ean platform, resides in correctly constraining the tecton ic processes, and styles and inten sities of crustal uplift th at have been at play. The writings of Birotcontains the seeds of much of the research that was subsequently carried out in these regions, ranging from high-elevation passive margin s such as the Scandian mountain belt and eastern Greenland (Peulvast 1985b, 1991), South Africa (Lageat 1982,1983,1987a), Madagascar (Petit 1971), northern Labrador (Andre 1982), western India (Gunnell 1996a), to low-elevation and more discontinuous margin s such as Wales (Battiau-Queney 1980, 1982, 1983, 1991b), south-west England (Coque-Delhuille 1987a), Ireland (Conde 1995) or Galicia (Vergnolle 1988).
