The Origins of Mountains approaches mountains from facts about mountain landscapes rather than theory. The book illustrates that almost everywhere, mountains arose by vertical uplift of a former plain, and by a mixture of cracking and warping by earth movements, and erosion by rivers and glaciers, the present mountainous landscapes were created. It also gives evidence that this uplift only occured in the last few million years, a time scale which does not fit the plate tectonics theory.Another fascinating part of the evidence, shows that mountain uplift correlates very well with climatic change. Mountain building could have been responsible for the onset of the ice age. It certainly resulted in the creation of new environments. Fossil plants and animals are used in places to work out the time of mountain uplift, which in turn helps to explain biogeographical distributions.

Regolith is the layer of broken and unconsolidated rock and soil material that forms the surface of the land and covers the bedrock nearly everywhere. An understanding of its properties and structure is very important in topics such as groundwater supply, soil conservation and exploration efforts for economic materials. Regolith, Soils and Landforms is a manual for students, professionals and researchers concerned with the practical examination and analysis of earth surface materials in the field. The text describes many economic aspects of regolith studies, such as the formation of mineral deposits, the importance of weathering zones and how the chemistry of regolith affects human health. Presenting a new view of the geological history of the earth, it places emphasis on the formation and destruction of regolith materials and provides a challenge for established concepts in landscape evolution. It will be an essential text to a wide range of readership including students of Geology, Geomorphology, Geography, Agriculture and Engineering as well as professionals dealing with regolith in their own work.

This book presents extensive and new information on the geomorphology of cratonic areas of southern South America. It includes valuable data relating to recurrent controversies in general geomorphology beyond the boundaries of South America and reveals the great need to integrate many different aspects of geomorphology in regional studies. With the focus on ancient landscapes and especially on planation surfaces it addresses the question of what processes could form such huge features, and how they can be preserved for so long. Many of the papers include maps of planation surfaces or other geomorphic units. The volume brings together an up-to-date, state-of-the-art collection of information on South American geomorphology, and shows beyond doubt that geomorphology is on the same time scale as global tectonics, biological evolution and major climate change. Some of the papers describe ancient geomorphological features of areas that have never been studied or published before, while others describe regions which are totally unknown to the public. The scope of the book extends from tropical latitudes north of the Tropic of Capricorn, south to freezing Patagonia in the “roaring fifties”, more than 3,500 km from north to south. Including over one thousand citations from geological and geomorphological literature, this volume will serve as a starting point for a whole new phase of studies of the fascinating landscape history of southern South America.
