EFFECT OF THE DETERMINATION OF THE BULK DENSITY ERROR OF REDUCING LAYER ON THE VALUE OF BOUGUER'S ANOMALY

Summary

Correct values of gravimetric anomalies depend on many factors. One of these factors is the possibility of precise determination of the bulk density of reducing layer. The problem of the effect of the bulk density error (m_σ) on the value of Bouguer's anomaly has been thoroughly analyzed in this article. The nomogram for determining the value of the error of anomaly depending on the error of the bulk density of reducing layer and the height (above sea-level) of the observation point (Fig. 1 and 2) has been elaborated on the basis of the results yielded from the carried-out analysis. To characterize the value of the error of anomaly one might give the figures as the examples and also take an appropriate attitude toward gravimetric maps in Bouguer's reduction being made in Poland.
