文摘
- •
The paper correlates deformational events at Venetia Mine with the surrounding Central Zone of the Limpopo Belt.
- •
A robust mapping dataset and downhole orientated drillcore provide rare insight into ductile deformation and sheath folding in the Central Zone.
- •
An implicit 3D model accurately reproduces the 3D geometry of upper-amphibolite to granulite facies, complexly deformed country rocks.
