Structural geology of stratiform lead-zinc deposits: case histories.

The deposits discussed are Mount Isa, Sullivan (Kimberley, British Columbia), Tom (Yukon) and Cirque (British Columbia). All of these exist in low grade metamorphic rocks, and therefore exhibit features resulting from deformation and metamorphism while still retaining primary depositional/diagenetic characteristics. Detailed structural analysis of a particular deposit aims to evaluate its structural morphology; determine its structural evolution; investigate the effects of deformation on ore and grade distribution; determine structural control of ore distribution both within the deposit and in the host sediments; understand sulphide/host rock lithologies; understand the development of ore textures and fabrics; and remove the effects of deformation and metamorphism in order to erect and evaluate genetic models for synsedimentary/diagenetic features. The analysis of each deposit concludes with a list of further references.
