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: In this article, the authors proposed that there are three types of gold deposits in Eastern and Central Transbaikalia (Trans-Baikal province), namely: (i) high-sulphide intrusion-related deposits with some signs of porphyry deposits, (ii) low-sulo-phide epithermal Au-Ag deposits, and (iii) low sulphides epithermorphic Au−Ag deposits.

TL;DR: The Aguablanca Cu-Ni orthomagmatic ore deposit is hosted by mafic and ultramafic rocks of the Aguablancas stock, which is part of the larger, high-K calc-alkaline Santa Olalla plutonic complex.

TL;DR: Orogenic gold mineralisation in the Lachlan Orogen of southeastern Australia and in other Phanerozoic fold belts has generally been assumed to be confined entirely to quartz veins as mentioned in this paper.

TL;DR: The Vani manganese deposit is located in the rugged NW sector of Milos Island as discussed by the authors, and it occurs within the Vani volcano-sedimentary basin, which is underlain by dacitic domes and flows of Upper Pliocene age.

TL;DR: The only Archean terrane (ca. 3400 Ma) known to date in the Guiana Shield is the Imataca Complex in Venezuela as discussed by the authors, which dates between 2.25 and 2.08 Ga.

TL;DR: In this paper, a fossil wood cell texture with pitchblende and coffinite was found at a sandstone-hosted roll-type uranium deposit, Xinjiang, NW China.

TL;DR: The porphyry Cu±Mo deposits in the southern Siberian craton and Northern Mongolia including subduction-, collision-, and rift-related igneous series of early Paleozoic to Mesozoic age, are all characterized by varying crustal contribution to their parent magmas and the presence of explosive breccias as mentioned in this paper.

TL;DR: In addition to the world-class epithermal deposits in the Monte Amiata area (Southern Tuscany) as mentioned in this paper, mercury production from the Levigliani and Ripa deposits in Apuane Alps is recorded from the cinnabar with minor pyrite in quartz gangue.

TL;DR: A carbonate-hosted stratabounded siliceous crust type (SCT) mineralization (base metal sulphides, barite, fluorite) occurs over large areas of the Carnic Alps and Karawanken in the Eastern Alps as mentioned in this paper.

TL;DR: In this article, the authors used halogen element diffusion halos over the Chadong As-Ag-Au deposit to predict concealed orebodies at the depth range of 0-200 m.

TL;DR: The first occurrence of dolomite-hosted, disseminated gold mineralization at Barhi and Jhal, in a Late Archean-Early Proterozoic metavolcano-sedimentary belt (Mahakoshal fold belt) in central India is reported in this paper.
