Gravity Field Determination in Croatia — Status Report

The first serious works on the determination of the Earth’s gravity field in Croatia began at the Faculty of Geodesy, University of Zagreb, nearly twenty years ago and they have been extremely intensified in the last few years. Detailed review of all efforts and preparations can be found in (Colic et al., 1993a). This poster presents the short survey of those investigations with the most interesting achievements. The final results for Croatian gravity field parameters, including the combination of different kinds of data - gravity anomalies, vertical deflections, satellite altimetry, topography, ... - are planned to be made public in the year 1995.

Similarities of and differences between three mountain belts at the border of the pannonian basin due to the behaviour of the mohorovičić discontinuity

SummaryThe Dinarides, the Eastern Alps and the Western Carpathians being situated at the borders of the Pannonian basin, are of very similar origin. Therefore, the results obtained in the investigation of correlations between Earth gravity field parameters (absolute geoid undulations, gravity anomalies), the surface topography and the shape of the Mohorovičić discontinuity, were compared. It was found that these three regions have the same basic characteristics, but also their own specific features. While the similarities follow clearly from these investigations, the found differences might partly be a consequence of non-uniformity and unmatched quality of data sets used for the three regions.

Kindredness of Three Mountain Belts at the Border of the Pannonian Basin — Deduced from the Behavior of the Mohorovičić Discontinuity

The Dinarides, the Western Carpathians and the Eastern Alps, situated at the borders of the Pannonian basin, are of a very similar origin. Therefore, a comparison of the results obtained in the investigation of relationships between geoid undulations, gravity anomalies, the surface topography and the Mohorovicic discontinuity shape, was effected. It came out that these three regions have mainly same basic characteristics, but also own specific features.

Comparing Various Solutions for the Mohorovičić Discontinuity Shape in the Dinaric-Pannonian Region

Strong linear relationships between gravity anomalies, absolute geoid undulations, topographic heights and Mohorovicic discontinuity depths have been detected on the Dinaric—Pannonian territory almost a decade ago. The prediction of Moho depths using the existing seismic data and these relationships has been gradually improved. This paper enlightens the present state of the art.
