Abstract : Maps of mean free air anomalies of the entire earth by data of I. D. Zhongolovich, W. A. Heiskanen and W. M. Kaula are presented. These anomalies which are a substitute for the isostatic anomalies are evidently connected with the heterogeneities in the mantle, which encompass vast territories. Noted is the confinement of the strongest anomalies to regions of increased tectonic activity. The translation discusses the gravitational field of the earth in regard to density heterogeneities, free air anomalies and mean air anomalies. There is a comparison of maps of free air anomalies for the entire earth, constructed by different authors and by various methods. Certain conclusions were reached on the basis of different factual data. These conclusions are also presented. (Author)
