Tectonic models for accretion of the Central Asian Orogenic Belt
TL;DR: The Central Asian Orogenic Belt ( c. 1000-250 Ma) formed by accretion of island arcs, ophiolites, oceanic islands, seamounts, accretionary wedges, and oceanic plateaux and microcontinents in a manner comparable with that of circum-Pacific Mesozoic-Cenozoic orogens is studied in this article.

Paleozoic accretionary and collisional tectonics of the Eastern Tianshan (China): Implications for the continental growth of Central Asia
TL;DR: In this article, the authors deal with the various tectonic units in the Chinese Eastern Tianshan orogenic collage in the Central Asian Orogenic Belt, and discuss the Paleozoic geological history of the several periods of accretion and collision of archipelago systems lying between the Tarim and southern Angaran continental margins.
Journal ArticleDOI
Gold Deposits in Metamorphic Belts: Overview of Current Understanding,Outstanding Problems, Future Research, and Exploration Significance
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.

The golden transformation of the Cretaceous plate subduction in the West Pacific
TL;DR: In this paper, a large-scale orogenic lode gold (Au) mineralization occurred contemporaneously with an abrupt change of ~ 80° in the drifting direction of the subducting Pacific plate, concurrent with the formation of the Ontong Java Plateau.
Journal ArticleDOI
Orogenic gold: Common or evolving fluid and metal sources through time
TL;DR: In this paper, the authors show that gold deposits of all ages, from Paleo-archean to Tertiary, show consistency in chemical composition, with high concentrations of CH 4 and/or N 2, common estimates of 0.01-0.36% H 2 S, a near neutral pH of 5.5, and salinities of 3-7.5.

Geochemistry of Hydrothermal Ore Deposits
TL;DR: In this paper, Skinner et al. discuss the relationship between hydrous alteration and its relationship to hydrous fluid composition in the formation of sulfide-sulfide ores.

Orogenic gold deposits : A proposed classification in the context of their crustal distribution and relationship to other gold deposit types
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.

ARC Assembly and Continental Collision in the Neoproterozoic East African Orogen: Implications for the Consolidation of Gondwanaland
TL;DR: The most important, rapid, and enigmatic changes in our Earth's environment and biota occurred during the Neoproterozoic Era (1000-540 million years ago; Ma).
