Book Description
This book is a collection of papers concerned with the processes and products of magma-sediment mingling and the origin of peperite. Three papers are concerned with physical modelling of magma-wet sediment interaction, whereas the majority of the papers describe a wide variety of peperite compositional and textural types, and discuss controls on their formation. The first paper reviews the current understanding of peperite generation, and serves as an extended introduction to the volume. Peperite is a common rock type generated in many volcanic and sub-volcanic environments. Its study is important for several reasons. Correct identification of peperite is critical in palaeoenvironmental reconstruction and relative chronology, as its presence can demonstrate contemporaneity of volcanism and sedimentation. Peperite may also record a snapshot of the processes that occur prior to hydromagmatic explosions, and which are otherwise not preserved in the resulting deposit. Its study can therefore provide information on the factors and mechanisms that influence the likelihood of such hazardous explosions. Peperite also indicates the presence of syn-volcanic sills that may be important sources of heat and/or fluids for co-eval hydrothermal systems.

Book Description
This title includes guides for field trips held in conjunction with the 2003 GSA Annual Meeting in Seattle. Topics covered include Glacial Lake Missoula and the Clark Fork Ice Dam; the Sauk Sequence in Utah; the geology of wine in Washington state; the Columbia River basalt and Yakima Fold Belt; Alpine glaciation of the North Cascades; and recent geoarchaeological discoveries in central Washington. Quaternary geology of Seattle, engineering geology in the central Columbia Valley, and the tephrostratigraphy and paleogeography of southern Puget Sound are also covered.

Book Description
There are continual rounds of annual conferences, special sessions and other symposia that provide ample opportunity for researchers to convene and discuss igneous processes. However, the origin of laccoliths and sills continue to inspire and confound geologists. In one sense, this is surprising. After all, don't we know all we need to know about these rocks by now? As testified by the diverse range of topics covered in this volume, the answer is clearly 'no'. This book contains contributions on physical geology, igneous petrology, volcanology, structural geology, crustal mechanics and geophysics that cover the entire gambit of geological processes associated with the shallow emplacement of magma. High-level intrusions in sedimentary basins can also act as hydrocarbon reservoirs and as sources for thermal maturation. In drawing together a diversity of perspectives on the emplacement of sills, laccoliths and dykes we hope to advance further our understanding of their behaviour.

Book Description
European geologists, many from former Soviet bloc countries, present 14 studies they delivered at an October 2002 workshop in Freiberg, Germany on the physical geology of sub-volcanic systems. The subject has not been so thoroughly examined since 1970, they say, and could be of interest to igneous petrologists, volcanologists, structural geologists

Book Description
This volume is an excellently written and beautifully illustrated textbook compiled by a multidisciplinary group of experts examining the production, transport and deposition of volcaniclasts (tephra and epiclasts) as well as their economic geology.

Book Description
One of our aims in the book is to provide geologists with a sound basis for making their own well founded interpretations. For that reason we cover not only concepts about processes, and the nature of the products, but also methods and approaches that may be useful in analysing both modern and ancient successions. Most importantly, we treat the diversity of products in volcanic terrains as facies, and we use the method of facies analysis and interpretation as a means of constructing facies models for different volcanic settings. These models will, we hope, be useful as norms for comparison for workers in ancient terrains. The idea for this book came into being between 1981 and 1982 when J. V. W. came to Monash University to take up a Monash Postdoctoral Fellowship. During this period a short course on facies analysis in modern and ancient successions was put together, integrating J.V.W.'s extensive volcanological experience in numerous modern volcanic terrains with R.A.F.C.'s extensive sedimentological and volcanological experience in older volcanic and associated sedimentary successions in the Palaeozoic and Precambrian of Australia. The enthusiastic response from the participants to the first short course, taught in May 1982, and to subsequent annual re-runs, encouraged us to develop the short course notes into this book. The idea for both the short course and the book arose because we felt that there was no single source available that comprehensively attempted to address the problems of analysing, interpreting and understanding the complexity of processes, products and stratigraphy in volcanic terrains.
