New data on geochemical features, fluid mode, age and potential ore content of granitoids of Isherim anticlinorium (North Ural)

open access: yesЛитосфера, 2018
Granitoids of Ishirim anticlinorium which is one of the major Precambrian structures of the North Urals, are poorly studied by modern geochemical and isotope-geochronological methods that led to the existence of different points of view on formation ...

DEVONIAN-CARBONIFEROUS MAGMATISM AND METALLOGENY IN THE SOUTH URAL ACCRETIONARY-COLLISIONAL SYSTEM

open access: yesГеодинамика и тектонофизика, 2021
The oceanic stage in the history of the South Urals completed in the Ordovician – Early Silurian. The Ordovician through Devonian events in the region included the formation of an island arc in the East Ural zone from the Middle Ordovician to Silurian ...

Deep-earth geodynamics and metallogenic peculiarities in the Kunashir-Urup chain of the Kuril Islands

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2019
The southern part of the Kuril island-arc system (from Kunashir to Urup islands) differs from the northern part (from Simushir to Paramushir islands) in its spatial arrangement relative to the subducting Pacific megaplate’s motion vector, greater number ...

Volcanogenic features of IOCG deposits of North Carajás, Brazil, and related constraining evidence

open access: yesJournal of the Geological Survey of Brazil
The magnetitic Cu-Au (IOCG) deposits of north Carajás, Amazonian Craton, Brazil, are hosted in the Neoarchean (2.76 Ga), dominantly basaltic-greywacke Itacaiúnas metavolcanic-sedimentary sequence that evolved in a continental rift setting.

Gold Metallogeny and Exploration

open access: yes, 1993
Within the last decade, the high and continuing demand for gold has prompted a global gold rush on a scale never before seen, not even in the heady days of Ballarat, California and the Yukon.

Metallogeny linked to mantle dynamics in the Sanjiang Tethys region as inferred from P-wave teleseismic tomographic study

open access: yes, 2017
The Sanjiang Tethys tectonic domain is one of the major metallogenic belts in China. The magmatism and metallogeny in this region have been variously attributed to break-off of the subducted slab, delamination of the lower crust or lithosphere, and ...

Geochemical Characteristics and Their Geological Significance of Zircon and Apatite From the Wunugetushan Porphyry Cu–Mo Deposit, Inner Mongolia, NE China

open access: yesActa Geologica Sinica - English Edition, Volume 100, Issue 3, Page 795-813, June 2026.
The key factors making the monzogranitic porphyry fertile for mineralization, including its high Cl, S, and H2O contents, high oxidation state, significant fluid exsolution, and multiple recharges of deep‐seated mafic magma, were all critical for the formation of the Wunugetushan porphyry Cu‐Mo deposit. ABSTRACT The Wunugetushan (Wushan) porphyry Cu–Mo
