  • Geophysics 210 September 2008
    Geophysics 210 September 2008 Geophysics 210 - Physics of the Earth A1: What is geophysics Geophysics: Application of physics to understand the structure and working of the Earth. Geophysics can be divided into exploration geophysics and geodynamics. Exploration geophysics is the process of imaging what is inside the Earth. Direct sampling in the Earth with drilling can only reach depths around 10 km so indirect methods are needed. Often used to describe commercial exploration, but includes investigations to depths of the mantle and core. All geophysical methods can be divided into active and passive techniques. In an active technique, it is necessary to generate a signal (e.g. in seismic studies sound waves are generated with an explosion or an earthquake). In a passive technique a naturally occurring signal is detected (e.g. the pull of gravity of a buried object). Geodynamics is the study of how the Earth works, and considers questions such as: -what drives plate motion? -what triggers earthquakes? -how is the Earth’s magnetic field generated? -how do continent-continent collisions build mountains? This field depends heavily on information derived from geophysical imaging. Advances in computer power now allow simulations of these processes in ever increasing detail and realism. A2 : Basic structure of the Earth • Radially symmetric to first order. • Crust – mainly silicate minerals, enriched in lighter elements (Na, Al) • Mantle – silicate minerals with more heavy elements (Fe and Mg) magnesium. Divided into upper and lower mantle (dashed line) • Outer core - liquid iron that convects rapidly. • Inner core – Lump of solid iron roughly the size of the moon • Crust and mantle are defined in terms of their distinct chemical compositions.

  • OIL and NATURAL GAS Within the General Field of the Earth Sciences
    118 EXPLORATION GEOPHYSICS - OIL AND NATURAL GAS Last year the Canadian Association of Physicists prepared a comprehensive review on the status and future of physics in Canada for the Science Secretariat of the Privy Council. The subject was treated in twelve parts, one of which related to the “Physics of the Earth” under the convenorship of Professor R. D. Russell, University of British Columbia. Professor Russell invited the C.S.E.G. Executive to submit a brief on the significance of geophysics from the viewpoint of society members. The report below was undertaken by the CSEG. Research Committee CompriS. ing the following members: Mr. C. H. Achesan, Chairman Mr. Hinds Agnew Mr. R. Jerry Brad Mr. R. Clawson Mr. E. T. Cook Mr. G. F. Coote Mr. R. J. Copeland Dr. J. A. Mair Mr. P. J. Savage INTRODUCTION Within the general field of the earth sciences, lies the subfield of “Ex- ploration Geophysics.” This study concerns itself with the application of the tools and methods of physics to explore the first few miles of the earth’s crust. It attempts to identify rock types and delineate their gross structure. The ability to do this has proved to be invaluable in the exploration for oil and gas, and in the mining and construction industries. It is an essential field of endeavour for the development of Canada’s natural resources. As it makes use of the tools and methods of physics, students trained in this discipline are essential to its further development. The research carried out by government and universities has been, and will prove to be, a valuable asset to exploration geophysics, the most recent examples being provided by advances in Communication Theory and Laser Research.
