New Terrestrial Native Iron Discovered on Earth's Surface

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Native iron is a major common mineral in lunar samples and meteorites but rarely occurs on Earth's surface, as its stability requires highly reducing conditions with very low oxygen fugacity. To date, native iron has mainly been found in basalts, ophiolites, and deep hydrothermal systems.

Arc Heat Flow and Magmatic Heat Budgets

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract We evaluate hydrothermal heat loss from 11 volcanic‐arc segments (∼6,000 km of arc length, ∼10% of the global total), motivated by the observation that much magmatic heat ultimately crosses the land surface as heated aqueous fluid. Heat loss takes place by volcanic eruption, geothermal heat conduction to the surface, fumarolic (vapor ...

Climate and Volcanic Activity Modulate Area–Distance Effects on Plant Diversity Along the Temperate–Subarctic Island Volcanic Arc

Journal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aims To evaluate how equilibrium (ETIB) and niche‐based (NTIB) island‐biogeography frameworks jointly explain taxonomic and phylogenetic diversity in a temperate–subarctic, volcanically active archipelago. Location Kuril Islands, northwestern Pacific (44°–50° N). Time Period Present. Taxon Vascular plants.

INTEGRATED GEOLOGIC-GEOPHYSICAL INVESTIGATION OF THE RATMANOV SUBMARINE VOLCANIC MASSIF (KURILE ISLAND ARC) [PDF]

Bulletin of Kamchatka Regional Association «Educational-Scientific Center». Earth Sciences, 2020
The article presents the results of integrated geologic-geophysical investigation of the Ratmanov submarine volcanic massif, located in the Kurile Island Arc, 15 km southeast of the Chirinkotan island. There is a small submarine volcano on the northwestern slope of the massif with a relative height of 400–450 m, dredging of which raised andesites and a

Cold Seep Communities in the Sea of Japan Are Species‐Poor and Dominated by a New Species of Provannid Snail

Journal of Zoological Systematics and Evolutionary Research, Volume 2026, Issue 1, 2026.
The Sea of Japan is a semi‐enclosed marginal sea in the northwestern Pacific whose bathyal communities exhibit a depauperate species diversity due to anoxic events during the last glacial maximum. Cold seeps associated with chemosynthetic ecosystems were discovered in this region over three decades ago, yet their fauna have not been characterised. Here,

Melt Architecture Under East Asian Volcanoes Revealed by Anisotropic Tomography

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Cenozoic volcanic rocks in East Asia are widespread across subduction zones, oceanic plates, and continental interiors. The generation of these volcanic materials is closely associated with partial melting of the upper mantle and the stagnation of the Pacific slab in the mantle transition zone.

Volcanic-glacial interactions: GIS applications to the assessment of lahar hazards (case study of Kamchatka)

Лëд и снег, 2015
On the Kamchatka peninsula, lahars or volcanogenic mudflows arise as a result of intensive snow melting caused by incandescent material ejected by volcanoes onto the surface.

Biological surveys reveal unexpectedly high faunal diversity at Nankai Trough methane seeps

Ecosphere, Volume 16, Issue 11, November 2025.
Abstract Cold seeps are chemosynthesis‐based ecosystems powered by microbial primary production that support diverse and specialized faunal assemblages in the deep sea. Despite Nankai Trough in Japan being a geologically active margin hosting numerous seeps, much of the faunal diversity remains undocumented.
