Center of Mass Estimation of Simple Shaped Magnetic Bodies Using Eigenvectors of Computed Magnetic Gradient Tensor
Computed Magnetic Gradient Tensor (CMGT) includes the first derivatives of three components of magnetic field of a body. At the eigenvector analysis of Gravity Gradient Tensors (GGT) for a line of poles and point pole, the eigenvectors of the largest eigenvalues (first eigenvectors) point precisely toward the Center of Mass (COM) of a body. However, due to the nature of the magnetic field, it i...
متن کاملLocation and dimensionality estimation of geological bodies using eigenvectors of "Computed Gravity Gradient Tensor"
One of the methodologies employed in gravimetry exploration is eigenvector analysis of Gravity Gradient Tensor (GGT) which yields a solution including an estimation of a causative body’s Center of Mass (COM), dimensionality and strike direction. The eigenvectors of GGT give very rewarding clues about COM and strike direction. Additionally, the relationships between its components provide a quan...

15 صفحه اولEstimation of Source Location Using Curvature Analysis
A quadratic surface can be fitted to potential-field data within 3×3 windows, which allow us to calculate curvature attributes from its coefficients. Phillips (2007) derived an equation depending on the most negative curvature to obtain the depth and structural index of isolated sources from peak values of special functions. They divided the special functions into two categories: Model-specific...
متن کاملcomparison of different methods for the estimation of depth, location and source-type of magnetic and gravity fields
the main goal of interpretation of potential fields (gravity and magnetic) data is determination of the buried source parameters including the depth, horizontal position, the structural index and the physical properties, which is magnetic susceptibility in the magnetic cases and density for gravity fields. for a large number of data it is so expensive modelling the data by using the inversion a...
