Field Geophysics (Geological Field Guide) - Tapa blanda

Sinopsis

Field Geophysics Second Edition John Milsom University College, London This handbook has been fully revised and updated to cover the advances that have been made in small scale geophysical surveying since the publication of the first edition in 1989. The techniques described are generally those that can be applied by teams of 1-4 people, using instruments which can, if necessary, be backpacked into the survey area. Additional coverage has been given to the use of electromagnetic methods in conductivity mapping and to the special requirements of investigations in archaeological and land-fill sites for very dense coverage and for different modes of data presentation. A new chapter has been added describing the applications of ground radar. Field techniques and equipment are discussed with particular emphasis on practical limitations, common problems and pitfalls (including those introduced by the increasing use of microprocessors in instrument control systems). Examples, tables and checklists are provided, together with numerous graphs illustrating the ways in which instrument responses and physical properties change with field parameters. The book is designed for anyone using small scale geophysics in the field. It is suitable for undergraduate and postgraduate students of geology and geophysics, as well as for professional geophysicists, geologists, hydrogeologists and archaeologists. The practical information it contains has been derived from the author's many years of experience as a consultant geophysicist.
