The study begins with a synthetic presentation of geological and geophysical data at this time. The geological data come from the detailed geological mapping superimposed over the previously elaborated geological maps (at scales 1: 200000 and 1: 50000). The data on the deep structure come from the magnetotelluric and seismic sections interpreted. Of course, the documentation obtained from previous referenced publications and the specialized sites brought an extra knowledge.
We performed a multiparametric correlative analysis of various geophysical parameters (Bouguer anomaly, Free Air anomaly, magnetic anomalies, electrical resistivity anomalies, etc.) as well as geodetic surfaces (geoid, quasigeoid, reference ellipsoid and topographic surface). Algorithms and programs used for filtering, smoothing and interpolating data were represented by mobile average with various rectangular windows, calculation of analytical expressions of trend polynomial surfaces, calculation of correlation coefficients with mobile windows and spectral analysis. From a methodological point of view, starting from the programs developed for the trend surfaces with different degrees, they allowed us to determine by an analytical expression a geophysical parameter (dependent variable) according to two independent variables (latitude and longitude). The residual values (those relevant for the surface structures) represent the difference between the measured real values and the calculated values of the trend surfaces. We also used the successive filtering of geophysical parameters, starting with the elimination of the planar trend, then the second-degree surfaces and finally the highest degree trend surface. The results obtained in this way, for geophysical parameters, we were able to correlate them with the surface geological elements as well as with the depth ones and the tectonic elements. |
