Annotation:

The paper gives a brief lithological characteristic and description of the patterns of the structure of the productive Osinskiy horizon of the Nepsko-Botuoba anteclise. According to the results of studies of rock radioactivity (gamma-ray, spectrometry), zones of increased natural radioactivity of the carbonate deposits of the Osinskiy horizon were identified and possible causes of its occurrence were formulated. According to the results of comprehensive laboratory studies, factors of endogenous and exogenous influence on the formation of zones of abnormal radioactivity values were identified.
