The thesis is a part of project "Gravity model of the Karlovy Vary granite pluton", The project is solved at the Faculty of Science, Charles University, Prague and it is supported by Grant Agency of the Czech Republic, grant 205/05/0156. The Karlovy Vary pluton is a part of larger body, The Krušné Hory Mts. pluton, which probably occurs beneath whole area of the Krušné Hory Mts. In the western part of these mountains The Karlovy Vary pluton forms a large outcrop of the granite body. The granites are source of a remarkable regional gravity low. Granites intruded in time interval of several milion years during and after a main deformation phases of the Variscan orogenesis. With regard to age, we recognize two main types and a lot of subtypes of granites. These types are different not only in their ages but also in geochemical composition. We studied if different types of granites are distinguishable also in petrophysical properties and in geophysical measurements in the field. Chosen methods were gravimetry and magnetometry. We measured a 3500 m long profile at the locality close to the Karlovy Vary town, where three types of the granites occur: Older Intrusive Complex (OIC), Younger Inrusive Complex (YIC) and transition type of the granite - microgranite (porhyric granite). Gravity measurements were...
