Ore Geology Reviews 

TL;DR: The orogenic gold deposits were formed during compressional to transpressional deformation processes at convergent plate margins in accretionary and collisional orogens as discussed by the authors, with gold deposition from 15-20 km to the near surface environment.

TL;DR: Orogenic gold deposits have formed over more than 3 billion years of Earth's history, episodically during the MiddleArchean to younger Precambrian, and continuously throughout the Phanerozoic as discussed by the authors.

TL;DR: The results of applying the above algorithms to epithermal Au prospectivity mapping of the Rodalquilar district, Spain, indicate that the RF outperformed the other MLA algorithms (ANNs, RTs and SVMs), showing higher stability and robustness with varying training parameters and better success rates and ROC analysis results.

TL;DR: In this paper, the authors used Landsat thematic mapper (TM) satellite images to identify two assemblages of hydrothermal alteration minerals; iron minerals; clays plus alunite.

TL;DR: In this paper, the authors compare the grades and tonnages of nodules and crusts in those two areas with the global terrestrial reserves and resources, and compare the two largest existing land-based REE mines, Bayan Obo in China and Mountain Pass in the USA.
