The papers in this Supplement volume were presented at a special session on Weathering and Soils at the 4th International Geomorphology Conference, Bologna, Italy, 28 August to 3 September 1997. They represent a range of topics in current research concerned with weathering and soils, and their relationships with geomorphology. Carnicelli (1999) provides a summary of the symposium.
Ben Brahim & Thiry and Bukowska-Jania & Pulina point out the importance of solution. These authors consider silica and carbonates in soils and sediments, and their relationships to the development of landforms. Chemical denudation is clearly important in many landscapes, but is often difficult to demonstrate and assess.
Driscoll & Arocena discuss soil profiles in British Columbia, and note their relationships to landforms and parent materials.
Weathering rates and processes form an important part of geomorphology. Papers by Hachinohe et al., Oguchi & Matsukura, and Waragai consider various aspects of weathering processes and rates. Hachinohe et al. demonstrate that weathering rates appear to slow with time, while the other two papers show that details of rock characteristics on the one hand and micro climate on the other, have an important influence of the nature and rates of weathering.
Finally, the paper by Tele Vieira demonstrates that a variety of modern processes act together to produce landform and regolith features in the modern landscape, while Migon presents evidence that shows the influence of tectonics and geomorphic stability on the survival of residual weathering mantles.
