Unfolding contents menu
The Unfolding option is used in the grade estimation and variography of deformed strata bound deposits. This can be applied to deposits where mineralisation is controlled by a structural surface that can be modelled. The Projection Model option to create a projection model by specifying two surfaces, either as grids or triangulations. The Bend Model option to locate samples near a point in space and to establish the relative position of the samples to that point as well as to each other. The Create LVA Model option to create a.tetra file for use in grade estimation, similarly to other options in Block > Unfolding.
The Create Anisotropy Model option to locate samples near a point in space and to establish the relative position of the samples to that point as well as to each other. The relative positions are not the standard Euclidean coordinates but are instead based on distances between the surfaces that define a seam or ore body.
