Distribution of magnetic disturbing objects of nepsk vault (central part of nepsk - botuobinsk anteklise)

The study deals with Nepsk vault, Katagansky region, Irkutsk distirict. The work is aimed at development of the technique of automated interpretation of aeromagnetic data under complex magnetic fields of Nepsk-Botuobinsk anteklise; studying main features of distribution of magnetic disturbing objects in central part of NBA. A technique of automated interpretation of aeromagnetic data is developed. An estimate of distribution of trap intrusions by depths is given. Mathematical support of automated interpretation of aeromagnetic data is implemented. An estimate of evolution of non-uniform zones of trap magmatism is given and geological-geophysical cuts of areas promising for search of oil and gas are constructed based thereof. The developments are implemented at RGA Irkutsk-geophysica. The effectiveness of development consists in an increase of geological information capacity of aeromagnetic survey and a complex of geologo-geophysical methodsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
