Abstract Orogenic gold deposits provide a significant source of the world’s gold and form along faults over a wide range of crustal depths spanning sub-greenschist to granulite grade faces, but the source depths of the gold remains poorly understoo

Controlled-source audio magnetotellurics (CSAMT) is a grounded electromagnetic imaging technique used primarily in the mining industry and is closely related to the marine controlled-source electromagnetic method (mCSEM) which is more familiar to the

Orogenic gold deposits provide a significant source of the world’s gold and form along faults over a wide range of crustal depths spanning sub-greenschist to granulite grade faces, but the source depths of the gold remains poorly understood. In thi

A subsurface volume that can be reliably interpreted in terms of geologically relevant attributes is a desirable objective for products from geophysics inversion workflows. Geophysics data contain uncertainties, however, and the solution of the inver

We have quantified the use of finite electric dipole lengths from the point measurement assumptions typical in 3D MT inversion modeling. Electric fields are measured across dipoles of typically 50 ...

Ground Magnetotelluric (MT) data acquired today are typically broadband, covering 0.001 to >1000 Hz with inter-site spacing typically at 500 to 1000 m. Airborne Z-axis tipper data (ZTEM) are sampled at higher spatial density but usually band-limited

Summary Controlled source, grounded electrode EM surveys have a long and successful history in mineral exploration geophysics, where the most commonly deployed configuration is CSAMT, which uses single, fixed, kilometre-long transmitter dipoles (e.g.

Summary Following from our recent work on joint inversion of MT, gravity, and MEQ data from the Darajat field ( Soyer et al, 2018 ), here we illustrate the pros and cons of quantitative integration of MT and gravity data through 3D joint inversion mo

Summary We have implemented 3D faults as discontinuity surfaces, of finite extent, in the regularization step of our non-linear inversion engine (RLM-3D), for both single domain and cross-gradient joint inversion cases, and applied this for geotherma
