A new method for 3-D magnetic data inversion with physical bound

Inversion of magnetic data is an important step towards interpretation of the practical data. Smooth inversion is a common technique for the inversion of data. Physical bound constraint can improve the solution to the magnetic inverse problem. However, how to introduce the bound constraint into the inversion procedure is important. Imposing bound constraint makes the magnetic data inversion a n...

ESINVM 3 D : A 3 D resistivity inversion package

We have developed an open source 3D, MATLAB based, resistivity inversion package. The forward solution to the governing partial differential equation is efficiently computed using a second-order finite volume discretization coupled with a preconditioned, biconjugate, stabilized gradient algorithm. Using the analytical solution to a potential field in a homogeneous half space, we evaluate the ac...

3-D magnetic inversion with data compression and image focusing

We deve lop a met hod of 3-D magne tic anomaly inver­ sion based on traditional Tikhonov regulariza tion the­ ory. We use a minimu m support stabi lizing functional to gene rate a sharp , focused inverse image. An iterative in­ version process is const ructed in the space of weighted model parameters that accelerates the converge nce and robustness of the met hod. The weighting functions are se...

Full 3-D inversion of electromagnetic data on PC

Ž . Ž . Three-dimensional 3-D electromagnetic EM inversion might be believed to require high-performance computers. Ž . However, with the rapid progress of recent computer technology, running 3-D inversions on personal computers PC is becoming a rational choice. This paper describes an attempt to carry out full 3-D inversions of synthetic frequency-domain EM data on a PC. In the inversion, a st...

Approximate resistivity and susceptibility mapping from airborne electromagnetic and magnetic data, a case study for a geologically plausible porphyry copper unit in Iran

This paper describes the application of approximate methods to invert airborne magnetic data as well as helicopter-borne frequency domain electromagnetic data in order to retrieve a joint model of magnetic susceptibility and electrical resistivity. The study area located in Semnan province of Iran consists of an arc-shaped porphyry andesite covered by sedimentary units which may have potential ...
