Book Description
This review of the geology of a classic area in the west of Ireland includes chapters on Dalradian stratigraphy and structure, syn-deformational magmatism, metamorphism, geochronology, and relationships with younger intrusions and cover rocks. It is accompanied by five colour-printed plates including a geological map of Connemara and geological cross sections and maps of Styne Head and Errismore, and gives accounts of other located exposures.

Book Description
This book contains a comprehensive field guide, including detailed itineraries and supporting data, to the Geology of Western Ireland, a classic site for world geology. It facilitates study into the rock record of the Neoproterozoic ‘birth’ to the Devonian ‘death’ of the Iapetus Ocean along the Laurentian (North American) margin. The enormous variety of lithologies and processes available for study in this spectacularly exposed region include: fluviatile to deep-sea sediments; layered ultramafic intrusions to reverse zoned granite batholiths; zeolite to eclogite facies metamorphic assemblages; continental rifting; subduction processes; island arc evolution; arc-continent collision; Andean margin development; and continent-continent collision. An introduction to the geology, that includes information relevant to the planning and execution of field trips in the region, is followed by nine chapters each providing the necessary background, field itineraries, exercises and points for debate, covering: the Laurentian basement and Neoproterozoic cover of North Mayo, Sligo, the Ox Mountains and Connemara; the metamorphic nappes and syn-orogenic intrusions of the Ordovician Grampian Orogeny; the Cambro-Ordovician subduction-accretion complex of Clew Bay; the obducted Ordovician fore-arc basin of South Mayo; the post-subduction flip late-Ordovician of South Connemara; the Silurian successor basins deformed during the final closure of the Iapetus Ocean; the late to post-orogenic Devonian sediments; the Devonian Granite batholiths ; and the post-orogenic Carboniferous cratonic sediments. Two final chapters summarise: the current tectonic interpretation of this region; areas for future research; and the extensive sources of geochemical and geophysical data.

Book Description
The Caledonides are a major orogenic belt that stretches from the Arctic, through Scandinavia, East Greenland, Britain and Ireland into the Atlantic coast of North America. Following the break-up of Rodinia, the Caledonides formed in the Palaeozoic by the drifting of various continents and their eventual aggregation in the Silurian and Devonian. The orogen subsequently fragmented during the opening of the Atlantic Ocean. This volume brings together 25 papers presenting the results of modern research that investigates the orogenic processes and the provenance of specific components of the belt. The contributions reflect different lines of research, linking traditional field studies with modern analytical techniques. In addition three overview papers summarize the main features of the belts in Scandinavia, Svalbard, East Greenland, Britain and Ireland, highlighting the advances made since the last major synthesis of the Scandinavian Caledonides 30 years ago, and discussing important open questions.

Book Description
Brings together a series of papers which explore various aspects of the deformation of continental lithosphere, covering different tectonic settings from the Palaeozoic to the present day. These include terrane accretion and juxtaposition, the exhumation of high-pressure terrains, and mechanisms of crustal extension and rifting.

Book Description
Heritage stones are building and ornamental stones that have special significance in human culture. The papers in this volume discuss a wide variety of such materials, including stones from Europe, Asia, North and South America, Africa and Australia. Igneous (basalt, porphyry, granite), sedimentary (sandstone, limestone) and metamorphic (marble, quartzite, gneiss, soapstone, slate) stones are featured. These have been utilized over long periods of time for a wide range of uses contributing to the historic fabric of the built environment. Many of these stones are of international significance, and so are potential Global Heritage Stone Resources, that is stones that have the requisite qualities for international recognition by the Heritage Stones Subcommission of the International Union of Geological Sciences. The papers bring together diverse information on these stones ranging from their geological setting and quarry locations to mechanical properties, current availability, and uses over time. As such the papers can serve as an entry into the literature on these important stones.

Book Description
Arc-continent collision has been one of the important tectonic processes in the formation of mountain belts throughout geological time, and it continues to be so today along tectonically active plate boundaries such as those in the SW Pacific or the Caribbean. Arc-continent collision is thought to have been one of the most important process involved in the growth of the continental crust over geological time, and may also play an important role in its recycling back into the mantle via subduction. Understanding the geological processes that take place during arc-continent collision is therefore of importance for our understanding of how collisional orogens evolve and how the continental crust grows or is destroyed. Furthermore, zones of arc-continent collision are producers of much of the worlds primary economic wealth in the form of minerals, so understanding the processes that take place during these tectonic events is of importance in modeling how this mineral wealth is formed and preserved. This book brings together seventeen papers that are dedicated to the investigation of the tectonic processes that take place during arc-continent collision. It is divided into four sections that deal firstly with the main players involved in any arc-continent collision; the continental margin, the subduction zone, and finally the volcanic arc and its mineral deposits. The second section presents eight examples of arc-continent collisions that range from being currently active through to Palaeoproterozoic in age. The third section contains two papers, one that deals with the obduction of large-slab ophiolites and a second that presents a wide range of physical models of arc-continent collision. The fourth section brings everything that comes before together into a discussion of the processes of arc-continent collision.
