This book brings together an overview of the recent geological history, active earth and biological processes and human settlement of New Zealand. Topics covered include the very active neotectonic and volcanic setting. Mountain geomorphic processes are examined and new ideas about landsliding are highlighted. The exceptional sedimentary archives of the Whanganui Basin are also presented. As one of two land masses that extend into the southern mid-latitudes, New Zealand is ideally located to investigate changes in Southern Ocean climate. Related to this, mountain glaciation in New Zealand is a focus in global climate change debates. New Zealand also has a unique biota due to its long isolation and is the last major land mass to be settled by people. Advances in DNA technologies have revolutionised our understanding of the histories and processes involved. The book provides a comprehensive review of existing work and highlights new ideas and major debates across all these fields.
The proceedings of the Eleventh International Basement Tectonics Conference is part of a major series of publications dealing with intraplate tectonics. The Eleventh Conference, held in Potsdam, Germany, presents aspects of the basement tectonics of Eastern and Western Europe; the first time they have been assembled in one meeting. Internationally recognised experts in a variety of fields review broad, key, integrative aspects of major fields which contribute to the understanding of the European basement and to geophysical methods of basement analysis. The book focuses mainly on the structure and history of the entire European continent. The recent political reorganisation of Europe has helped to promote several international programs aimed at understanding the deep basement of the European continental features. Accordingly, the majority of the papers included in this volume deal with different aspects on the structure and evolution of the European continent and its various orogenic belts and postorogenic features. Topics range from modelling of the thermal evolution of basement rocks, fabrics in deformed rocks, and geophysical features of basement units to intrusion and concomitant deformation of the basement. Similar aspects are addressed in further chapters focusing on other Phanerozoic cratons and are grouped around topics of current interest: the problem of extrapolation and correlation of geological and geophysical data from basement rocks, and the mechanisms of basement exhumation in the evolution of orogenic belts.
In diamond alluvial deposits, the information about the spatial distribution of stone size is of crucial importance for the quantitative characterisation of the different areas of the deposit. In fact, the value of the diamond reserves depends strongly on the distribution of stone sizes: between two areas with the same grade, the most valuable is the one with larger stones. The geological genesis of the mineralization, related with the transport and deposition of stones in trapsites, can create separated spatial areas, corresponding to different stone size. To characterise these distinct areas, the non smooth transitions between them should be accounted for, in the estimation of internal properties. An extended version of zonal control of geostatistical estimation (Soares et ai, 1995) proposed in this paper, aims to characterising the classes of size histogram for each geological unit, avoiding the smooth effect. For this purpose the morphology of each geological unit is obtained by using two distinct criteria: i) first, the points of each unit are classified according to the local and global probabilities of belonging to each unit (Soares, 1992); ii) in a second classification, the optimization technique of Simulated Annealing is used to rearrange the pre-classified points in order to impose, in the final morphological maps, the spatial variability of experimental samples (Goovaerts, 1994). A case study of a diamond alluvial deposit with two geological units with distinct stone size histograms is presented.
Focusing on issues of when and how Archean crust in the craton was formed, this PhD thesis book presents major research outcomes of field based metamorphic, geochemical and geochronological investigations on Meso-Neoarchean basement rocks from Shandong Province in the Eastern Block of the North China Craton. Based on major findings and new data, the author proposes that the formation and evolution of Archean crust was governed by mantle plumes, not by plate tectonics. As one of the oldest cratonic blocks in the world containing rocks as old as 3.85 billion years, the formation and evolution of North China Craton is still controversial. Therefore this book will be of value to anyone interested in the evolution of cratonic blocks and Precambrian geology.
Computational Subsurface Hydrology: Fluid Flows offers practicing engineers and scientists a theoretical background, numerical methods, and computer codes for the modeling of fluid flows in subsurface media. It will also serve as a text for senior and graduate courses on fluid flows in subsurface media in disciplines such as civil and environmental engineering, agricultural engineering, geosciences, soil sciences, and chemical engineering. Computational Subsurface Hydrology: Fluid Flows presents a systematic derivation of governing equations and boundary conditions of subsurface fluid flow. It discusses a variety of numerical methods, expounds detailed procedures for constructing finite element methods, and describes precise implementation of computer codes as they are applied to subsurface flows. Four computer codes to simulate vertically integrated horizontal flows (FEWA), saturated flows with moving phreatic surfaces in three dimensions (3DFEWA), variably saturated flows in two dimensions (FEMWATER), and variable flows in three dimensions (3DFEMWATER) are attached to this book. These four computer codes are designed for generic applications to both research and practical problems. They could be used to simulate most of the practical, real-world field problems. If you would like a copy of the diskettes containing the four, basic general purpose computer codes referred to in Computational Subsurface Hydrology: Fluid Flows, please email Gour-Tsyh Yeh at the following address : [email protected]
Progressive failure has been a classical problem in the field of geotechnical engineering and has attracted considerable attention in connection with slope stability and foundation problems. It is associated with strain localization or shear banding and is also related to damage in material structures. As knowledge of the progressive failure mechanism increases, it is now necessary to establish effective communications between researchers and engineers. The International Symposium on Deformation and Progressive Failure in Geomechanics provided an opportunity for discussing recent advances in this area. A total of 136 papers were contributed from 22 countries. As well as these, the symposium proceedings also contain 8 interim technical reports on the subject by the members of the Asian Technical Committee of the International Society for Soil Mechanics and Foundation Engineering and the Japanese Geotechnical Society National Committee on Progressive Failure in Geo-structures.
Landforms constitute boundary surfaces between different components of the earth system (atmosphere, hydrosphere, biosphere, pedosphere, lithosphere). At these locations most of the human activity on earth takes place. This central position evokes a bi-directional interaction with the other spheres of the earth system. S- tial landform structures strongly affect processes of other earth system components. At the same time, the land-surface is shaped by the in uence of these processes impacting geomorphologic processes and landform morphometry. These interactions are the focus in the Research Training Group 437 "Landform - a structured and variable boundary layer" at the University of Bonn in Germany. Funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) the Research Training Group is a multidisciplinary research programme for postgraduate studies. Disciplines involved in this programme include: biology, c- matology, computer sciences, geodynamics, geology, geomorphology, geophysics, hydrology, mathematics, meteorology, pedology, and remote sensing. These diff- ent disciplines offer various scienti c approaches, theories, methods and data for the study of landforms within their speci c paradigms. Over a period of ten years (1998-2008) more than 25 PhD projects have been completed. Dedicated to ongoing and completed research activities of the Research Training Group an international symposium titled "Landform - structure, evolution, process control" was held at the Department of Geography, University of Bonn, in 2007.
Cratons and Fold Belts of India, is a unique attempt at presenting geological characteristics and evolution of the fold belts and the cratonic areas of the Indian shield. The author has evaluated the different evolutionary models for each fold belt in light of all the currently available geological and geochronological informations that are clearly listed. Shortcomings, if any, of each model are stated and a viable geodynamic model is presented for each fold belt. The book is self-contained it includes an introduction to the processes of mountain building, especially plate tectonics theory with its application to the evolution of the Himalaya as an illustrative example so that the reader can better appreciate the novel approach to the evolution of Proterozoic fold belts. The author eschews a detailed account of the fold belts for a clear description of all the concepts that go into building models. It is primarily written for graduate students, teachers and for those geoscientists who aspire to know all about the Indian shield."
An overview of the advances made in the last decade and a half in this field. Based on an advanced graduate level course, the book represents fundamental insights into the structure of the physical theory of the large-scale dynamics of the oceans. The author has maintained throughout a blend of analytical and numerical results so as to achieve as deep a physical understanding of the dynamics of the large-scale circulations as possible. The results of the theories are compared with observations and the success or inadequacies of the theories are highlighted. Topics of particular interest are: theory of the wind-driven circulation, the thermocline, the equatorial circulation and the abyssal circulation. Much of the material - previously scattered throughout the literature - has been collated here for the first time.

The thesis of Anna Alexandra Vackiner focuses on the geometric architecture and tectonic evolution of the Permian series, combining seismic interpretation (3D block), field studies in an analogue basin (Panamint Valley in California), as well as 2D restoration of representative cross sections through time in order to illustrate the complex interaction between multiphase extension, inversion and salt diapirism. It will be of major interest for exploration geologists involved in tectonically complex areas. - Francois Roure, August 2012 This thesis improves the understanding and localization of the Upper Rotliegend II tight gas reservoir rock facies. It provides insights into the detailed Upper Rotliegend II palaeo-topography and local tectonically induced sediment thickness changes prior to a multi-phase tectonic overprinting. The research presented in this study further focuses on the tectonically induced synsedimentary facies distribution in transtensional continental settings on the basis of a comparison with a modern field analogue, which enables a detailed analysis of the reservoir rock's distribution and its properties. The study is rounded off with an analysis of the influence of the multiphase tectonic overprinting on the mature Upper Rotliegend II reservoir rocks.
The Second Volume of Equilibrium between Phases of Matter, when compared with the First Volume, by H.A.J. Oonk and M.T. Calvet, published in 2008, amounts to an extension of subjects, and a deepening of understanding. In the first three sections of the text an extension is given of the theory on isobaric binary systems. The fourth section gives an account of the thermodynamic analyses of four isobaric binary key systems, highlighting the power of empirical, (exo)thermodynamic correlations. The fifth section is devoted to the thermodynamic description of ternary systems. The last three sections concentrate on the properties of materials, and the phase behaviour of systems under the conditions of high temperature and high pressure conditions that prevail in the interior of the Earth. A new equation of state is the subject of the sixth section. In the seventh section a move is made to statistical thermodynamics and vibrational models; the description of the systems has changed from mathematical to physical. The last section is on the system MgO SiO2, looked upon from a geophysical point of view. Throughout the work high priority is given to the thermodynamic assessment of experimental data; numerous end-of-section exercises and their solutions are included. Along with the First Volume, the work is useful for materials scientists and geophysicists as a reference text. Audience Volume II is a lecture book for postgraduate students in chemistry, chemical engineering, geology and metallurgy. It is highly useful as a recommended text for teachers and researchers in all fields of materials science. "
The Workshop on Parameter Identification and Inverse Problems in Hydrology, Geology and Ecology, Karlsruhe, April 10-12, 1995, was organized to bring to gether an interdisciplinary group drawn from the areas of science, engineering and mathematics for the following purposes: - to promote, encourage and influence more understanding and cooperation in the community of parameter identifiers from various disciplines, - to forge unity in diversity by bringing together a variety of disciplines that attempt to understand the reconstruction of inner model parameters, un known nonlinear constitutive relations, heterogeneous structures inside of geological objects, sources or sinks from observational data, - to discuss modern regularization tools for handling improperly posed pro blems and strategies of incorporating a priori knowledge from the applied problem into the model and its treatment. These proceedings contain some of the results of the workshop, representing a bal anced selection of contributions from the various groups of participants. The reviewed invited and contributed articles are grouped according to the broad headings of hydrology, non-linear diffusion and soil physics, geophysical methods, mathematical analysis of inverse and ill-posed problems and parallel algorithms for inverse problems. Some of the issues adressed by the articles in these proceedings include the rela tion between least squares and direct formulations of inverse problems for partial differential equations, nonlinear regularization, identification of nonlinear consti tutive relations, fast parallel algorithms for large scale inverse problems, reduction of model structures, geostatistical inversion techniques."
This volume follows a Specialized Symposium on "Mantle denudation in slow spreading ridges and in ophiolites," held at the XII EUG Meeting in Strasbourg, spring 1993. During the meeting it was felt that the contribu tions to the Symposium justified a volume presenting its main scientific achievements. The present title of the volume shows that the center of inter est has slightly shifted with respect to the initial objective: in order to under stand the processes involved in accretion taking place at oceanic ridges, it is crucial to study the interaction between uppermost mantle and lower crust. The approach favored here is that of petrological and structural analysis of oceanic rocks in present-day oceanic ridges combined with similar studies in ophiolites. Rock specimen collected by submersibles or dredge hauls in oceanic ridge environments provide a "ground truth." However, except for areas such as the MARK (Mid-Atlantic Ridge ne ar Kane fracture zone) where, thanks to multiple submersible dives, the local geology is known with aprecision even better than in many onshore ophiolites, mutual rela tionships between uppermost mantle and lower crust are poorly known. In contrast, onshore ophiolites provide a necessary large-scale picture built up over many years of structural and petrological mapping."
This book presents an up-to-date analysis of ocean-atmosphere interaction. Well known experts examine diverse subjects such as ocean surface waves, air-sea exchange processes, ocean surface mixed layer, water-mass formation, as well as general circulation of the oceans, El Nino and Southern Oscillation (ENSO), and the deep-ocean circulation. Other areas described are basic dynamics, data analysis techniques, numerical modelling, and remote sensing. This book is primarily aimed at graduate and senior undergraduate courses in the area of ocean-atmosphere research.
This book provides a summary of geodynamic results from Iceland that presently are found in a great number of scientific articles, but have not been collected before in a book. The ever increasing number of scientists interested in geology and geophysics of Iceland should find the book a "must" to gain knowledge about previous work and the status of knowledge about Iceland.
