Special Issue Information

Dear Colleagues,

The shift to green technology enormously increases the global demand for critical commodities. This makes it necessary to improve nowadays mineral exploration techniques and strategies to both increase the success rate for finding new economic deposits and to exploit resources that were inaccessible in the past. To achieve this, many different types of geoscience data and information are combined in advanced multi-methodologically approaches to develop complex high-resolution exploration models in modern mineral exploration. Geophysical methods play a central role in such kind of exploration since they allow non-invasive systematic surveying, and often have a significant depth penetration. They provide insightful geological information as 2D and 3D physical models. Sometimes, geophysical anomalies are even directly sensitive to the target mineralization and can give information about the location, size, shape, and type of a deposit.

Most geophysical methods that have been successfully used in mineral exploration for a long time use the concept of inversion to reconstruct physical parameter distributions in the subsurface from the measured data. Geophysical inversion techniques are developing very fast for providing useful models for geological interpretations and in defining the targets for mineral exploration from various geophysical data. With an increasing capability of computing devices, 3D inversion of large geophysical datasets is possible now, which was a very difficult task few decades ago. Geophysical inversion methods and their use in mineral exploration stretch to a vast area of local (iterative and linearized inversion) and global optimization inversion (stochastic inversion) and consider even applications of machine learning—both directly in the inversion or indirectly in interpretation of the inverted data. Much effort has also been made to improve the resolution of inversion results and accordingly to make their models more reliable for geological interpretation by combining data either from different geophysical methods (joint inversions) or by integrating geophysical data with other geoscience data (e.g., constrained inversions).   

In this special issue, we are inviting papers that deal with geophysical inversion developments (e.g., improved resolution, meaningful geological constraints, joint inversion) to all types of geophysical methods (e.g., gravity, magnetic, electrical and electromagnetic methods, seismic methods and even remote sensing methods such as hyperspectral imaging) and surveys (e.g., airborne, ground, offshore and borehole) and their applications in defining the mineral exploration targets in case studies. This also includes contributions for inversion techniques applied for deep-seated and unconventional mineral deposits e.g., marine sulfides.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Minerals is an international peer-reviewed open access monthly journal published by MDPI.
