... Australia ( Belousov et al., 2016 ) and the Geological Survey of South Australia (D. Gregory, unpub. report, 2015), where pyrite from a large number of ore deposits in both states was analyzed. Additional data from various ore deposits have been analyzed subsequently, leading to the current database...

It is thus proposed here to describe the evolution of the Tasmanides in terms of tectonic cycles, in the South American sense, to encompass depositional/magmatic as well as contractional deformational histories of rock packages developed along...

Excluding the “supergiant” (>2,500 tonne Au) Witwatersrand deposits of South Africa, Archean cratons contain some of the world's largest gold deposits...

... and 8,500 t Au, respectively. Most of the sig nificant gold deposits (>100 t Au) are concentrated in a few narrow, highly endowed gold belts along which the deposits cluster into camps, commonly spaced every 30 to 50 km. Gold deposits of both cratons show similar tonnages and grades, and their size...

...). The subsidence of the South Mayo Trough floor and the change in tectonic setting of the volcanism we would equate with the sudden uplift of Connemara during the D3 and D4 events (Yardley 1976) which led to the deposition of the Derry Bay Formation. This implies that the Grampian metamorphic peak in Connemara...

... and Robertson, 2012 ). This is the case at the Lancefield Au deposit, where stacked weathered profiles in each sedimentary unit (Permian, Tertiary, Quaternary) allowed transfer of Au, As, Cu, and Zn across the weathered profiles (paleosols) as they evolved. Although regolith anomalies are weak, especially...

The onset of basinal deposition was Late Cambrian, and sedimentation was apparently continuous thereafter until at least late Early Devonian ( Lenz 1972 , 1982 ; Norford 1996 ). The trough...
