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.

A detailed study of the masonry defences of one England’s most important Roman sites. Erected in c. 270 AD, the masonry walls of the Roman town of Silchester (Calleva Atrebatum; Hampshire, S. England) are part of the third system in a series of defensive works. They stand today to a height of almost 5m and are composed of up to seven lifts or stages, each consisting of a flint core and facing (now almost completely robbed away), capped by a string-course of large blocks and slabs that stretches across the full width (c. 3m) of the walls, formed of a wide variety of rock-types foreign to the district.

This short introduction aims to provide archaeologists of all backgrounds with a grounding in the principles, materials, and methods of geology. Sections include coverage of main rock-forming minerals and classes of rocks. Geological maps and structures are introduced, and the elements of geological stratigraphy and dating are explained and related to archaeological experience. Fluvial and coastal environments are important archaeological landscapes and their formation processes, sediments and topography are outlined. Stone for building, implement-making, tool-making, and making mortar are all discussed, followed by an introduction to clays and ceramics. A final chapter introduces metallurgical landscapes: metalliferous ores, mining and smelting, and metal-making industries. 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. Table of Contents 1.

This book, first published in 1985, is a dramatic revision of Dr. Allen's earlier book. Completely restructured, more comprehensive and more concerned with fundamental physical principles. It is intended for the senior undergraduate and beginning postgraduate student in Earth Science. It covers general physic in order to understand the small scale mechanically formed features of detrital sediments. "The coverage is very thorough and the ideas are presented in a lively text written in an interrogative style which constantly poses questions to the reader and suggests lines of enquiry. The text is widely illustrated. Highlights include the exceptionally thorough introduction to the basic physical principles of sedimentation and the lively and varied accounts of flow in meandering channels and turbulence." Terra Cognita "I was unable to read more than a few pages without encountering some new and stimulating idea. Does not resemble any other sedimentology textbook. The great strength of this book, as of much of Allen's other work, is in applying physical reasoning and simplified mathematical modelling to sedimentologic problems. Allen here reminds me of Bagnold: Both have performed highly original and seminal analyses." Sedimentology
