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: Gold deposits in metamorphic terranes include those of the Precambrian shields (approx 23,000-25,000 t Au), particularly the Late Archean greenstone belts and Paleoproterozoic fold belts, and of the late NeoproTERozoic and younger Cordilleran-style orogens (approximately 22,000t lode and 15,500 t placer Au), mainly along the margins of Gondwana, Laurentia, and the more recent circum-Pacific) as mentioned in this paper.

TL;DR: Gold-dominant intrusion-related deposits are a less coherent group of deposits, which are mainly Phanerozoic in age, and include a few world-class, but no unequivocal giant, examples as discussed by the authors.

TL;DR: In this paper, the authors used an ion microprobe (SHRIMP II) to analyze trondhjemitic magmatism at 2.90-2.95 Ga in the Kongling area of the Yangtze craton, south China, about 150 km south of the Permian-Triassic Qinling-Dabie-Sulu orogenic belt.
