Abstract

During its formation, Tungus syneclise basits, according to the physical and geological laws of formation, generated in bodies (sills, dikes, etc.) petromagnetic taxa (PMT) which are characterized by the certain statistical values of density and magnetic parameters. According to the nature of their distribution, PMT are subdivided on petromagnetic groups (PMG) and petromagnetic heterogeneities (PMHs). In its turn, PMT is composed of petromagnetic complexes (PMC), conforming to the magmatic phases of the basits intrusion. PMT allows more securely zoning of the Yakut diamondiferous province closed by the trap areas in order to develop a methodology of prospecting for primary diamond deposits, as well as isolating structural and tubular types of anomalies over kimberlite pipes based on gravity-magnetic exploration materials.
