The paper provides the results of geomagnetic servey of Vulcanolog and Kocebu guyots (Magellan seamounts) in the Pacific. Only the volcanic rocks that compose the guyots' core may cause the magnetic field anomalies recorded above the guyots. The tomographic interpretation of the anomalous magnetic field ΔTa helped distinguishing the feeding magmatic channels in the guyots' edifices.

Keywords: Magellan seamounts, guyots, Vulkanolog, Koceby, geomagnetic survey, tomography.
