VOXI Fundamentals Training CourseThis course will provide you with the skills to model gravity and magnetic data in VOXI. The course will cover key aspects such as data preparation, forward modelling and inversion best practice, Magnetization Vector Inversion (MVI) and constraining inversions with geological data.

The course uses hands-on activities to demonstrate: key considerations for data preparation, testing acquisition hypotheses with forward modelling, auxiliary parameters for inversion setup, best practices for inversion modelling, and finally exploring the inversion solution space. Participants will have the opportunity to create models during and after the workshop using VOXI Earth Modelling.
