apparatus is generally not required for the making of My aim in this book is simple. It is to set out in a logical useful sedimentological experiments. Most of the equip way what I believe is the minimum that the senior undergraduate and beginning postgraduate student in ment needed for those I describe can be found in the kit the Earth sciences should nowadays know of general chen, bathroom or general laboratory , and the materials most often required - sand, clay and flow-marking physics, in order to be able to understand (rather than form merely a descriptive knowledge of) the smaller substances - are cheaply and widely available. As described, the experiments are for the most part purely scale mechanically formed features of detrital sedi ments. In a sense, this new book is a second edition of qualitative, but many can with only little modification my earlier Physical processes of sedimentation (1970), be made the subject of a rewarding quantitative exer which continues to attract readers and purchasers, inas cise. The reader is urged to tryout these experiments much as time has not caused me to change significantly and to think up additional ones. Experimentation the essence of my philosophy about the subject. Time should be as natural an activity and mode of enquiry for has, however, brought many welcome new practitioners a physical sedimentologist as the wielding of spade and hammer.
The climate of the Earth has undergone many changes and for those times when geologic data are widespread and abundant the Mesozoic appears to have been one of the warmest intervals. This was a time during which the single continent Pangea disintegrated into continental units similar to those of today, a time when there were no significant polar ice caps and sea level was generally much higher than at the present time, and a time when dinosaurs apparently dominated terrestrial faunas and the flowering plants evolved. Understanding this alien world, ancestral to ours, is intrinsically interesting, intellectually challenging, and offers opportunities for more effective targeting of sites where commercially important geological resources may be found. It also provides critical insights into the operation of coupled Earth systems (biospheric, atmospheric, hydrospheric and geospheric) under extreme 'greenhouse' conditions, and therefore may have relevance to possible future global change. Our intention in organizing this Discussion Meeting was to bring together those who gather and interpret geologic data with those who model global climates from first principles. The community of workers who study the Quaternary have made significant advances by integrating and comparing palaeodata and climate model experiments. Although we have focused not on the Quaternary 'icehouse' but on the Mesozoic 'hothouse' climate we are well aware that approaches used in the study of the Quaternary may have relevance to earlier times.
This short introduction aims to provide archaeologists of all backgrounds with a grounding in the principles, materials, and methods of geology. Each chapter ends with a short reading list, and many have selected case-histories in illustration of the points made. Included is a glossary of technical terms.
Chief Constable Piet Deventer, recently married and now a father, is thrown into turmoil by twin tragedies - a young woman is murdered at a music festival, only hours after Piet's own baby daughter is abducted. Forced to put aside his personal woes and focus on the murder, Piet finds himself in a seedy world of drugs and rock'n'roll. He meets Harriet, the dead woman's sister, who has a shocking confession - might the two crimes be connected after all. Racing against the clock, Piet must untangle the web that connects the dead woman, the festival and his daughter, before it's too late. Corruption runs deep in the second fast-paced mystery featuring Piet Deventer, from master of 1970s crime, J.R.L. Anderson.
