Book Description
Four concrete pads 7.6 m x 7.6 m x 0.5 m thick were constructed in Thailandfor calibration of airborne gamma-ray spectrometers. They comprised a lowradioactivity background pad, a potassium pad, a uranium pad and a thoriumpad. The background pad was constructed of masonry sand and cement, theuranium and thorium pads with a small quantity of uranium and thorium oreadded to the same background matrix, and the potassium pad from feldspar andcement. The uranium ore, from Canada, was in radioactive equilibrium and alow emanator of radon. The thorium ore, a separated monazite beach sand, andthe feldspar were both obtained in Thailand. This report presents a detailed account of calibration pad construction.

Book Description
In 1978, an international consortium of scientists from Canada, Denmark, the United Kingdom, Iceland, the United States, and West Germany successfully completed a research deep drilling project in Iceland. These scientists formed the International Crustal Research Drilling Group to organize further deep drilling investigations and to compare the results with those from the Deep Sea and Ocean Drilling Projects. From 1982-85, five holes were drilled at three sites in Cyprus to study the Troodos ophiolite. The drilling was part of an integrated petrological, structural, and geophysical study of the ophiolite, involving both field mapping and diamond drilling. This report is the third of three on the project, discussing holes drilled through the pillow lava succession and giving descriptions of the cores along with other geological, geophysical, and geochemical data.

Book Description
Treatise on Geophysics, Second Edition, is a comprehensive and in-depth study of the physics of the Earth beyond what any geophysics text has provided previously. Thoroughly revised and updated, it provides fundamental and state-of-the-art discussion of all aspects of geophysics. A highlight of the second edition is a new volume on Near Surface Geophysics that discusses the role of geophysics in the exploitation and conservation of natural resources and the assessment of degradation of natural systems by pollution. Additional features include new material in the Planets and Moon, Mantle Dynamics, Core Dynamics, Crustal and Lithosphere Dynamics, Evolution of the Earth, and Geodesy volumes. New material is also presented on the uses of Earth gravity measurements. This title is essential for professionals, researchers, professors, and advanced undergraduate and graduate students in the fields of Geophysics and Earth system science. Comprehensive and detailed coverage of all aspects of geophysics Fundamental and state-of-the-art discussions of all research topics Integration of topics into a coherent whole

Book Description
The Geological Survey of Canada has been involved with the calibration of ground and airborne gamma-ray spectrometers since it constructed the first calibration facility for airborne spectrometers in 1968. Recent analysis of the calibration data obtained from the GSC facilities at Uplands airport, Ottawa, showed that the calibration constants were poorly known because of uncertainties in the radioelement concentrations of the pads. To improve the Canadian calibration facilities for both ground and airborne gamma-ray spectrometers, small sets of transportable pads 1 m x 1 m x 30 cm and weighing about 675 kg were constructed specially for calibrating portable spectrometers in the summer of 1988. Because of problems of radon leakage and inhomogeneities in the pads, a new set of uranium pads was constructed in the summer of 1989. This paper describes the design and construction of these small transportable pads and shows how they can be used for the calibration of both ground and airborne gamma-ray spectrometers.

Book Description
The present volume is the result of activities within the scientific programme "Response of the Earth System to Impact Processes" (IMP ACT) of the European Science Foundation (ESF). The ESF is an association of 67 national member organisations devoted to scientific research in 24 European countries. The IMPACT programme is aimed at understanding meteorite impact processes and their effects on the Earth System. Launched in 1998 for a duration of 5 years, the programme is now supported by 15 ESF membership countries. The programme of meteorite impact research and operates through deals with all aspects workshops, exchange programs, and short courses. The 4th IMPACT programme workshop "Meteorite Impacts in Precambrian Shields" took place on May 24-28, 2000, in Lappajarvi, western Finland. A total of 84 scientists from 19 countries from Europe, North America, and Africa participated in the workshop. During the workshop, 43 oral, 31 poster, and several video presentations were made. An exhibition of impactite rocks from Finnish craters and two excursions were organised. The excursion to impact melt rock outcrops of the Lappajarvi structure took place during the workshop. The Karikkoselka and Saaksjarvi impact structures in south-central Finland were visited during the post-meeting excursion.
