Regolith Geology and Geomorphology
Providing fundamental discussion of regolith properties andchemistry, this book considers many landscape situations andfeatures, whilst linking process to position, geochemistry andtime. Presenting information from an Australian perspective itprovides new insights into the subject, which are developed awayfrom the yoke of traditional Northern Hemisphere ideas andconcepts.
* Presents a new approach to the problems of understanding regolithgeology and landscapes
* Presents the general aspects and principles of regolith
* Chapters present views on landscapes and their evolution, thenature of minerals, the behaviour of water at a landscape level andthe exploration of water behaviour at various scales in regolithmaterials
* Investigates methods of conveying information about regolith viamaps and in GIS packages
