About one cause of abnormal variations of gravity

The article presents the results of measurements of tidal variations in the building of the Institute of Geology and Petroleum Technology of Kazan Federal University from September 2012 - March 2013, demonstrating the presence of a new type of sources of variations of the gravitational field that need to be considered when conducting high-precision field monitoring for the purposes of oil and gas geology, as well as providing results of the calculation of the parameter K, and showing its change over time
