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

Вестник 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 ...

Metallogeny of subduction zones [PDF]

Vestnik MGTU, 2017
The paper deals with the multistage mechanism of the Earth's crust enrichment in ore elements in underthrust zones. The processes of metamorphism and the formation of hydrothermal solutions at pulling of the watered oceanic lithospheric plate into the ...

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

Journal 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.

Metallogeny of Greenland

Ore Geology Reviews, 2016
Abstract Greenland is the largest island on Earth, with 80% of its area covered by a thick ice sheet. The coastal areas are underlain by variable rocks ranging from Eoarchean to the most recent ages. Greenland has a mineral exploration tradition since its colonization in the 18th century, and mining of cryolite started in 1854.

Event Deposits Recorded Over the Past 800 kyr in IODP Hole U1433A (South China Sea): Implications of a Revised Methodology for Chronology and Paleoclimate Reconstruction

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Instantaneous event deposits such as turbidites, debrites, and slumps are common and frequently occur in marginal seas. These instantaneous deposits represent seconds to days in duration, and can therefore significantly impact age‐depth models and interpretation of paleoclimate history based on thick sedimentary sequences recovered in deep ...

What Earth Erases: Weathering Diversity of Mineral Phases Formed in a Highly Reduced Environment Hosted in Aubrites

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Meteorites serve as an exceptional source of insight into our planet and the Solar System. Most meteorite fragments were recovered hundreds to thousands of years after their fall, and therefore exhibit varying degrees of terrestrial weathering, which has altered or completely removed weather‐sensitive mineral phases.
