Title: Recent Trends in Geological-Geophysical Exploration and Methods of Improving Use of Geophysical Data

Author(s): R. Clare Coffin (2)

Abstract:

Since 1942 the use of gravimetric methods has increased in the United States approximately 200 per cent, seismic methods 50 per cent, core drilling 100 per cent, and the magnetic investigations 70 per cent. The impact upon geological thinking because of this continued increase of geophysical effort is discussed. Full advantage offered by these methods and combinations of methods is not being made. A better use of the low-cost methods is pointed out. With the tremendous increase in the use of the gravity method there has not been a corresponding improvement in the proper understanding of its possible use and its limitations. The gravity method is discussed in some detail. A tremendous improvement in our geological thinking and a better use of geophysical data are possible y an education of "district" or "grass-root" geologists in geophysical concepts and a freer use of this information. A trend in this direction is noted, but the need of an accelerated move in this trend is emphasized.
