- Abstract
A vast bibliography is available on the volcanic structures in Călimani-Gurghiu-Harghita, from which we could extract tectonic and geological information that can be corroborated with geophysical data. The geomagnetic field maps were built on the data contained in the measurement catalogues in the archives of the Geological Institute of Romania. The data contained in these catalogues is not uniformly distributed, and high-density measuring areas (in areas of interest on valleys and accessible areas) alternate with areas with a very poor coverage (in areas of low interest and areas with a hard-accessible relief), leading to the need for mediations and filters made before interpolation. The gravimetric maps built on the published data and the data available at the International Gravimetric Bureau were filtered according to mobile mediation procedures and trend surfaces of different degrees. This paper is a preliminary geophysical and geological study in the project "The realization of 3D geological / geophysical models for the characterization of some areas of economic and scientific interest in Romania".
