PART 1. A REGIONAL ANALYSIS OF CRUSTAL STRUCTURE IN NORTH AMERICA. PART 2. A STUDY OF THE PROBLEMS ASSOCIATED WITH THE PREDICTION OF GRAVITY IN EUROPE.

Abstract

The report is contained in two parts. Part I is an analysis of present gravity prediction procedures in the light of geophysical data concerning the crust and upper mantle. The assumptions on which these procedures are based (areas in isostatic equilibrium, relationship between Bouguer values and elevation, secondary control of Bouguer values, effects of near surface changes in geology) and their effects are discussed. Part II analyses the problems of predicting gravity in Europe. The geophysical factors related to these problems (a continental block bounded by deep water, intense tectonic deformation, acid and basic intrusives, lack of seismic measurements, glacial loading) are reviewed and the results tabulated.
