The basement areas represent greater than two-thirds of outcropping bedrock fabric throughout our planet's continents. in the past 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 realizing of landscapes and landforms in igneous and metamorphic terrains at various latitudes. in addition, it covers a large box of research collected on 4 continents and addresses the problem at a variety of spatial and timescales. it really is a terrific quantity not just for post-graduate geomorphology scholars but additionally for geoscience students enthusiastic about igneous petrology, quaternary geology, actual geography, soil technological know-how and land use planning.

15 . Preservation of planation surfaces in formerly glaciated regions : an example from the Forez Mountains, Massif Central, France (after Etlicher 1986). In spite of its southerly location, the Forez massif (c. 45° of latitude) was partly covered by a small ice cap in the Quaternary. Far from destroying the pre-existing topography, the stagnant plateau ice contributed to the preservation of the Cenozoic land surface.

The more conspicuous and elevated basement massifs of Europe are mountainous regions that have been subjected to more intense, medium-wavelength up doming and intense faulting than most shields in the Arctic and the Tropics. , Permo-Carboniferous) graben sediment fills, while preserving the discordant Mesozoic cover (Saint-Die basin: Vosges; Brive basin: eastern Perigord); • bedrock fault scarps (south-eastern border of the Massif Central). More exceptionally,there are instances of low-elevation planation surfaces truncating both the warped (Limousin) or faulted (Rouergue) basement and its peripheral Mesozoic sediment cover in the form of a pediment-like continuum: this configuration is particularly striking in the Rhone corridor between Lyonand Avignon,where the aggregate throw of existing faults exceeds 1500 m.
