asep + d method: identification of anomalous areas of the earth's lower crust

摘要

abstract asep + d method: identification of anomalous areas of the lower earth crust. A method for use in identifying anomalous areas of the lower crust of a region of the earth is provided, comprising providing information regarding the region's mohorovicic discontinuity geometry, the mohorovicic discontinuity representing a transition between the upper mantle and the crust. lower region, determining the geometry of an intracrustal layer of the region, the intracrustal layer representing a transition between the lower crust and the middle or upper crust of the region, using observed gravimetric data to determine the density distribution between the intracrustal layer and discontinuity. of mohorovicic, and comparing the density distribution determined with a reference density distribution or lower crust reference value, the comparison enabling the identification of anomalous areas of the lower crust of the region.
