Geophysical investigations in the territory of Bolgar state historical and architectural museum-reserve in 2014

The results of geophysical investigations which was carried out in 2014 in the territory of Bolgar State Historical and Architectural Museum-Reserve are reviewed in the article. Territory of Bolgar State Historical and Architectural Museum-Reserve is part of the UNESCO protected sites. The set of works included wide range of geophysical investigations: magnetometry, gravimetry, electrical prospecting and georadar. The main goal of investigations was detecting and localization of archaeological objects remnant (houses, mausoleums, kilns, etc.). Magnetometry was the basic method during carrying out the works. Magnetic measurements are used in the practice of archaeological investigations very widely due to the high informativeness and productiveness of this method. The major search objects are the brick bases and building walls, accumulation of fired ceramic, the remnants of furnace construction for various purposes. Georadar survey, gravity and electrical prospecting were used for localization of nonmagnetic objects. It is identified a line of objects differing in its properties and purpose as a result of research. There are furnaces, mausoleum bases, remains of domestic buildings. Methodology for conducting of field experiments has been refined and optimized in the process of carrying out of geophysical investigations.
