GEOLOGICAL STRUCTURE OF EASTERN SUBPARPATHIANS IN MUNTENIA AS REFLECTED BY THE GRAVITY ANOMALY

Abstract

Based on a geographical material involving: the Bouguer anomaly map calculated for average densities, three simulations of the regional and local successive anomaly separated by square networks with sides of 1, 2 and 4 km, the structure of the gravity anomaly was analyzed namely: the distribution of the belts of the major gradient, the regional anomaly (morphology of the regional anomaly, separation degree of the regional anomaly, presence of a local anomaly with deep geological sources, gravimetric effects of maximum), the local anomaly (modification of the morphology and the intensity of the terms of the local anomaly, modification of the orientation systems of the great axes of the local terms, variation of the contours of the maximum and minimum zones with the investigation depth), the correction profiles transverse to the major geological structures of the area. The gravimetric elements analyzed allowed the simulations (the structural geological-gravimetric maps regarding the architecture of both of the crystalline basement and of the overlying sedimentary deposits). The tectonic data contained in this map give information about: the structure of the crystalline, the structure of sedimentary deposits, the causal relations between the structure of sedimentary deposits and the structure of the substratum.
