This book deals with magnetic anomaly maps and their properties. These properties are essential to modeling the elimination of the uncertainty problem of buried archaeological structure locations and depths. To this end, several models are presented and their quantitative properties are studied. Numerical simulations have been created, confirming theoretical results that were obtained.
A collection of 35 largely technical lectures from the Sandbjerg Conference held in 1999, examine metallurgical evidence from Scandinavia and Northern Europe as well as reporting on developments in scientific analytical techniques. Divided into five sections, papers discuss particular types of iron production and settlement; regional studies; metallographic investigations of artefacts and sites; metallographic regional studies; Geophysical prospecting and archaeomagnetic dating. The majority of articles relate to Scandinavia but there are reports on iron-smelting and specific finds and sites in Italy, Germany, England, Greece, France, Ukraine and Wales.
This combination of textbook and reference manual provides a comprehensive account of gravity and magnetic methods for exploring the subsurface using surface, marine, airborne and satellite measurements. It describes key current topics and techniques, physical properties of rocks and other Earth materials, and digital data analysis methods used to process and interpret anomalies for subsurface information. Each chapter starts with an overview and concludes by listing key concepts to consolidate new learning. An accompanying website presents problem sets and interactive computer-based exercises, providing hands-on experience of processing, modeling and interpreting data. A comprehensive online suite of full-color case histories illustrates the practical utility of modern gravity and magnetic surveys. This is an ideal text for advanced undergraduate and graduate courses and reference text for research academics and professional geophysicists. It is a valuable resource for all those interested in petroleum, engineering, mineral, environmental, geological and archeological exploration of the lithosphere.
The subjects of the papers that make up the volume vary from the preparation of national maps to examples of the many uses of regional maps. The anomalities that are discussed range in areal dimension from hundreds of kilometers to tons of meters. The majority of the papers illustrate the utility of the maps in mapping structures and lithologic variations wirhin the continenetal crust, the configuration of the crystalline basements rocks, zones of crustal weakness, distribution of extrusive and intrusive igneous rocks and the geometry of sedimentary basins. Most cases are drawn from the United States and Canada, but examples from Europe, Africa, South America and Asia are included.
The Hidden Link Between Earth's Magnetic Field and Climate offers a new framework of understanding and interpretation for both well-known and less known relations between different geophysical and meteorological variables which can improve the quality of climate modeling. The book reviews the most current research on both current and paleo data to introduce a causal chain of interactions between the geomagnetic field, energetic particles which bombard the Earth's atmosphere, ozone and humidity near the tropopause, and surface temperature. The impacts of these complicated interactions is not uniformly distributed over the globe, thus contributing to our understanding of regional differences in climatic changes and the asymmetrical ozone distribution over the globe. - Covers the newly discovered autocatalytic cycle for ozone production in the lower stratosphere, providing a better understanding of the heterogeneous distribution of ozone globally - Outlines a mechanism for the lower stratospheric ozone influence on the temperature and humidity of the upper troposphere - Provides a single resource on research in energetic particles' modulation by heterogeneous geomagnetic fields, mechanisms of the influence of particles on the atmospheric ozone, and the influence of ozone on climate
Complete publication of the Prehistoric, Sarmatian and Late Avar settlement at Gyoma 133 (Békés County Microregion). This is a full excavation report on work carried out between 1986 and 1988, the last season being in advance of development. The bulk of material is of Sarmatian (Roman) date and involves three occupation levels, the second involving extensive evidence of metallurgy. Particularly interesting are the results of animal bone study which allow a new picture of Sarmatian agriculture to be built up. The Sarmatians were great horsemen and the discovery of articulated remains of horses and dogs seem to indicate ritual treatment of these important animals.
