Palaeoweathering, Palaeosurfaces and Related Continental Deposits


Book Description

The study of palaeoweathering provides vital clues about pastcontinental environments, the correlation of sedimentary depositsand processes such as the rate and timing of uplift and erosion. This volume (based partly on research presented at IGCP 317Palaeoweathering Records and Palaeosurfaces) contains contributionsthat use both geochemical and physical approaches to the study ofpalaeoweathering problems. The former are particularly relevant toour understanding of past climates and climate change; the latterhave applications in the understanding of mass balance betweenrates of erosion and deposition. Palaeoweathering, Palaeosurfaces and Related ContinentalDeposits illustrates the multidisciplinary nature of the subject,the diversity of techniques and, above all, the vital contributionthe subject makes to the reconstruction of ancient continentalenvironments. This book will be of great value to sedimentologists,soil scientists and geomorphologists.

Climatic Change and Variability in Southern Africa


Book Description

This book examines the history and mechanisms of climatic change in the southern hemisphere, with emphasis on southern Africa. The crucial question, one which affects the lives of millions, is what determines whether there will be rain or drought. Professor Tyson examines this problem first in the context of geologic history. He then discusses present-day circulation and the manner in which the atmosphere modulates wet and dry spells. He proposes a circulation model to account for paleoclimatic changes over the subcontinent during the last 25 millenia. The material presented here represents research accumulated over a period of 17 years. Nothing similar exists for any country in the southern hemisphere.
