Eigenvectors of the gravity gradient tensor caused by the simplified sedimentary basin models shown in Fig. 5. The maximum eigenvector and minimum eigenvector are indicated by red and blue, respectively. a Eigenvectors on the sedimentary basin formed by normal faults. When the sedimentary layer is in contact with the basement by normal fault, the dip of the maximum eigenvector follows the dip of the normal fault. b Eigenvectors on the sedimentary basin are formed by reverse faults. When the sedimentary layer is in contact with the basement by reverse fault, the dip of the minimum eigenvector follows the dip of the reverse fault
