Curved Slopes,raction of three broad sets of controls, one set being structural, the second being lithological, and the third being erosional. The difficulty is increased by the variation of the curved forms; these range from domes and smooth “slick rock” slopes, through alcoves, arches, and natural bridges, to h

Chemical Weathering and Cavernous Weathering,stant to weathering according to Goldich’s scale; estimates of relative chemical erosion rates for major rock types (Meybeck 1987) place sandstones with mica schists and granites (rates relative to granite 1–1.3), below volcanics and shales (1.5–2.5) and most metamorphics (5), and well below carbona

Erosional Forms,he dominant process of shattering is still debated, it seems that disintegration due to frost action is very important in highly porous and fractured rocks, like sandstone, under cold climates (see Chap. 6). The breakdown of rock by fatigue, induced by high frequency cycles of solar heating, also ha

Conclusion,y, and to add to them our own field observations. In this sense our efforts can be seen as a sequel to to the foundations laid in Mainguet’s admirable monograph. Providing a much broader geographical range of examples was, therefore, the obvious task to be tackled, and we have attempted to do this b

Book 1992 geochemical and dynamic points of view. The worldwide examples include classic areas of sandstone research such as the Colorado Plateau, Saxony, France and England, but also emphasize the sandstone lands of the southern hemisphere. The authors give evidence for climatic influences on sandstone land
