Abstract
A joint mapping of two type of data - geophysical gravity data in terms of Total Horizontal Gradient (THG) and geological data for the distribution of known metal ore deposits, occurrences and mineralization in Bulgaria, is presented in a regional scale. For the purpose the whole territory of Bulgaria is divided in 1270 areal elements E of size 10×10 km. The number V1 of metal ore objects, and the length V2 (km) of gravity lineaments (THG, mGal/km), that appear in every single element E, are used as input data. Thus, a space index of coincidence, Qi = [(V1+V2)/√(V1 2+V2 2+C)]i, can be calculated in the areal elements Ei, i=1,2, …, N. The space distribution of this index gives us the integrated geological-geophysical information which can be used for revealing of different characteristics such as common origin, similar tectonic environment, etc.
