The creation of 3D models is commonplace in many disciplines. Models are often built from a collection of tessellated surfaces. To apply numerical methods to such models it is often necessary to generate a mesh of space-filling elements that conforms to the model surfaces. While there are meshing algorithms that can do so, they place restrictive re...

The underdetermined geophysical inverse problem is inherently non-unique, requiring additional information to recover geologically interpretable solutions. This additional information commonly includes petrophysical and structural measurements. It can also involve 3D geological Earth models, e.g. ore deposit models commonly created during delineati...

To be reliable, Earth models used for mineral exploration, or other subsurface investigations, should be consistent with all available geological and geophysical information. Geophysical inversion provides the means to integrate geological data such as lithology and structure, physical property data such as measurements taken on rock samples, and g...

... Taking a homogeneous property of magnetic susceptibility or density contrast for each cell into account, forward formulations of potential field data can be calculated for any s-sided polygon like a triangle cell (Blakely 1995, pp. 184-209;Liu et al. 2015a;Lelièvre et al. 2015Lelièvre et al. , 2018Singh 2020;Galley et al. 2021). For simplification, the potential field observations are set in a data vector d obs , and a linear operator or a Jacobian matrix (F) can forward the physical properties to the data. ...
