CORRELATION BETWEEN GRAVITY AND MAGNETIC FIELDS ON THE TERRITORYOF BULGARIA
Abstract
Correlation studies have been made between the gravitational field (Bouguer anomalies - G) and the magnetic field (common vector (T) and the vertical component dZ) for the territory of Bulgaria. The map data is in digital format, which makes it easier to calculate. The correlation itself is estimated from -1 to 0 and from 0 to +1, which means that a positive correlation is possible in the case of increased values of both parameters and vice versa - decreasing values are associated with reduced values. This forms a positive correlation. A negative correlation is observed when both parameters have minimum values. Zero correlation means - NO correlation (both parameters are min-max or max-min). The calculations from the maps give a clear picture of the positive and negative correlations and the ability to calculate areas with significant positive and / or negative correlations The results might be used for the interpretation of the studied potential fields in case of structural, regional and / or local changes in the gravity and magnetic fields, and their respective sources.
