Physical sedimentology is essentially an observational science. It is important to not only look hard at and think about sedimentary rocks and modern sediments and processes in the field, but also to strengthen one's intuitions and resolve one's uncertainties by frequently experimenting in the laboratory. This book sets out in a logical way the basic information that a senior undergraduate and immediate postgraduate needs to know of general physics, in order to understand the smaller-scale detrital sediments. It includes a large number of laboratory experiments to illustrate the theories described. This book should be of interest to senior undergraduates, immediate postgraduates.
