ASEP+D METHOD: IDENTIFYING ANOMALOUS AREAS OF THE EARTH'S LOWER CRUST |
摘要 |
There is provided a method for use in identifying anomalous areas of the lower crust of a region of the earth, comprising providing information relating to the geometry of the Moho for the region, the Moho representing a transition between the upper mantle and the lower crust for the region, determining the geometry of an intra-crustal layer for the region, the intra-crustal layer representing a transition between the lower crust and the middle or upper crust for the region, using observed gravity data to determine a density distribution between the intra-crustal layer and the Moho, and comparing the determined density distribution to a reference density distribution or reference value for the lower crust, the comparison enabling the identification of anomalous areas of the lower crust for the region. |
