“…Notably, the mineralised zone does not correspond to any obvious geological feature, trending at a low angle to most of the surface geological structures. Lisitsin et al (2014) concluded that the metallogenic zone is controlled by a major deep crustal domain boundary, independently inferred on the basis of coincident changes in the geochronology and geochemistry of Carboniferous to Permian felsic magmatic rocks and regional metamorphic grades, supported by crustal seismic data (Korsch et al, 2012). The inferred deep crustal domain boundary, represented by the boundary between the Herberton and Tate Igneous subprovinces , has the strongest spatial association with known significant gold deposits compared to any other geological feature recognised in the region (Fig.…”
