Gold metallogeny in Iran; implications for gold exploration and conceptual modelling

Geochemistry: Exploration, Environment, Analysis, 2023
Significant progress in the classification, definition and understanding of the main Au deposit types could significantly aid improvements in Au exploration. Because of the wide occurrence of Au in the central part of the Tethyan Eurasian Metallogenic Belt, Iranian structures composed of more than 17 zones (arcs and blocks) are considered as having one

Gold potential of the Pan African Trans-Sahara belt and prospect for further exploration

, 2020
The Trans-Sahara belt is one of the mobile belts formed during the Pan African orogeny that spans between ~870 and ~550 Ma. The Trans-Sahara belt was formed as result of the collision between the converging West African craton, Congo craton, and the ...

Simulations of gold exploration samples

Applied Earth Science, 2001
AbstractA computer program, GOLDSIM, is offered that determines the sampling distributions of samples taken from gold-bearing lots. The lot is split into size fractions that are weighed and assayed. It is then modelled in terms of the equivalent gold grains in the size fractions and these data are fed into GOLDSIM.
