DECOMPOSITION OF THREE-DIMENSIONAL MAGNETOTELLURIC DATA- By Xavier Garcia and Alan G. Jones
Decomposition of magnetotelluric data into a local galvanic 3D distortion matrix
and a regional 2D Earth caused a quantum leap in our understanding of complex data and
our ability to handle those data. The Groom-Bailey method is the most widely adopted tensor
decomposition approach, and rightly so given its physical basis and its separation of distortion
parameters into determinable and indeterminable parts.
