Book Description
Presents information from the primary abiotic forces defining the system, and from the present hydrology, biogeochemistry and physics of major sites of organic carbon production of the McMurdo Dry Valleys. Additionally, research on the physical, chemical, and biological properties of the dry valley soils is included. The role of environmental management in long-term ecological studies is also addressed. The accompanying CDROM provides details and scale to visualize the McMurdo Dry Valleys from an ecosystem perspective.

Book Description
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 88. This volume focuses on the volcanic, fluid, sedimentary, and tectonic processes occurring in the trencharc-backarc systems of the western Pacific—a natural regional focus for studies of these themes. The results of ocean drilling and associated site surveys in the western Pacific have brought fundamental changes to our understanding of volcanism, crustal deformation, fluid circulation, and sedimentation in active margins and marginal basins. Our goal here is to synthesize the results of ocean drilling in a multi-disciplinary manner, including a comparison of the findings from drilling legs having similar themes, and to emphasize the significance of these results to the broader geoscience community.

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.

Book Description
This volume contains a collection of papers presented as distinguished guest lectures at the International Conference on ``The Origin of Arcs'' held at the University of Urbino in September 1986, under the joint sponsorship of the European Union of Geosciences and the Italian Geological Society. The workshop on island and mountain arcs has been organized with the aim of increasing our understanding of the intrinsic nature of orogenic and post-orogenic processes, on the basis of empiric factual data, rather than particular theoretic models. Quite often a trivial piece of field data appears to bear much more weight than many fascinating hypotheses put forward by the human mind. This seems to be much more valid in geology, where a special method is necessitated by the particular nature of the geological phenomena and the time concept. Every general law deduced should be rooted in the study of the earth's development in geological time. It is the editor's opinion that there must first be an inductive picture by means of geological methods and then it must be interpreted by geophysicists in the light of physical laws. The geological method must serve, besides, to test the historical credibility of geophysical theories. It is clear that these two methods, the geological-historical one and the geophysical one, must be complementary and the one must not substitute the other. Since the problem of the structure and origin of arcs is open to several solutions, different factors being still unexplained, all correctly deduced opinions are considered by the editor. The contributors to this pre-conference volume have been asked to present essential geological results, as concrete as possible, on some basic problems, such as: Are the island and mountain arcs primary or induced features? How have these orogenic festoons developed into their similar regular shapes? What are the relationships between "primary" active arcs and "secondary" mountain arcs? What is the dominant deformational factor in the bulging of the arc? What is the real nature and tectonic significance of the Benioff zone? These papers have been grouped into five more or less natural sections, of which three are defined on the basis of geography. But of course several range broadly and the classification serves only to channel the discussion in a practical way.

Book Description
This book consists of a collection of papers presented at the NATO Advanced Research Workshop (ARW) on "Crust/mantle Recycl ing at Convergence Zones," held in Antalya, Turkey, between May 25 to 29, 1987. The workshop was attended by 36 earth scientists from ten countries and 28 papers were presented. Crust/mantle recycling is one of the most fundamental processes in the Earth. The study and understanding of this process requires the consideration of the Earth as a whole system including the atmosphere, the hydrosphere and the core, as well as the crust and the mantle; effective interdisciplinary collaboration is therefore essential to our progress. The Antalya ARW gave us the opportunity to assemble key specialists from relevant branches of the earth sciences and to address our state of knowledge. This ARW proved to be very useful in attaining an interdisciplinary, mutual understanding among specialists from diverse fields such as isotope and trace element geochemistry, mineral physics, theoretical geophysics, seismology, experimental petrology, and structural geology.
